  However, according to the conventional seawater battery, a large amount of seawater is required as an electrolyte, and since it is necessary to immerse the positive electrode and the negative electrode in the seawater stored inside, it is difficult to handle and handle, and can be easily carried, Could not be activated. Moreover, long-term storage was difficult.

  Accordingly, an object of the present invention is to provide an application battery that is easy to carry and operate and an emergency power supply apparatus using the application battery.

  Another object of the present invention is to provide an application battery that can be stored for a long period of time and can be used as an emergency power supply, and an emergency power supply apparatus using the application battery.

  Still another object of the present invention is to provide an application battery having very excellent voltage and current characteristics during initial and long-term use, and an emergency power supply apparatus using the application battery.

  According to the present invention, there is provided an application battery that includes a housing and a plurality of cells provided in the housing, and operates by pouring water into the housing during use, and each of the plurality of cells has a positive electrode. A carbonized cloth to be configured; a positive electrode lead electrode electrically connected to the carbonized cloth; a salt-containing cloth provided in close contact with the carbonized cloth; and a water absorption provided in close contact with the salt-containing cloth. A metal sheet formed of a material having a higher ionization tendency than that of the positive electrode, and a negative electrode lead electrode electrically connected to the metal sheet. And a shrinkable cover member that crimps the carbonized cloth, the positive electrode lead electrode, the salt-containing cloth, the paper sheet, the metal plate, and the negative electrode lead electrode to each other. The salt-containing cloth impregnates a multi-layer woven cotton cloth with salt. Application made up of cloth Pond is provided.

  In a state where the applied battery is not operated, liquid such as fresh water, salt water, seawater or the like is not introduced into the housing, and therefore, the inside is in a state where no liquid exists, so that it is very easy to carry and store. In addition, since a reaction hardly occurs unless a liquid is injected, long-term storage is possible. When operating the application battery, when a small amount of liquid such as tap water is injected into the housing, the liquid slightly accumulated at the bottom of the housing is transferred to the paper sheet having water absorption, and the entire salt-containing cloth is wetted. The salt contained in the cloth is eluted in the liquid, so that the salt-containing cloth and the paper sheet function as an electrolyte medium between the positive electrode and the negative electrode. As a result, a discharge reaction due to hydrogen ions occurs in the vicinity of the negative electrode. On the other hand, in the positive electrode of the carbonized cloth, electrons do not react with hydrogen ions, and electrons try to move from the negative electrode to the positive electrode, generating an electromotive force. In this way, the salt-containing cloth is provided in close contact with the carbonized cloth, the paper sheet having water absorption is provided in close contact with the salt-containing cloth, and the metal formed on the paper sheet with a material having a high ionization tendency. Since the plates are provided in close contact with each other, a small amount of liquid can be operated as a battery only by contacting a paper sheet. Further, since the carbonized cloth, the positive electrode lead electrode, the salt-containing cloth, the paper sheet, the metal plate, and the negative electrode lead electrode are pressure-bonded to each other by the shrinkable cover member, the distance between the negative electrode and the positive electrode can be kept substantially constant. . Furthermore, the attachment of the shrink cover member enables the electrical connection between the carbonized cloth and the positive electrode lead electrode and the electrical connection between the metal plate and the negative electrode lead electrode, and this connection operation can be performed only by attaching the shrink cover member. Since it can be carried out reliably, the work process becomes very easy and the manufacturing cost is also low. In particular, according to the present invention, as the salt-containing cloth, a single cloth having a multi-layered woven cotton cloth having two or more layers containing salt is used, so that the initial voltage and the initial current are significantly increased. In addition, the decrease in voltage and current after elapse of time is very small.

  The carbonized cloth is a carbonized cloth of a woven cloth, a knitted cloth, a woven or knitted cloth or a nonwoven cloth obtained by heating carbonization of a raw fiber body made of a woven fabric, a knitted cloth, a woven or knitted cloth or a nonwoven fabric made of cellulosic fibers.

More preferably, it is provided.

  It is also preferable that the metal plate is a flat plate made of a magnesium material.

  Each of the plurality of cells includes a positive electrode lead wire electrically connected to the positive electrode lead electrode and a negative electrode lead wire electrically connected to the negative electrode lead electrode, and the positive electrode lead wire and the negative electrode lead wire are connected in series. It is also preferable that a pair of external lead wires are configured by being connected in parallel. By connecting a plurality of cells in series and / or in parallel, an applied battery having a desired voltage and current capacity can be obtained.

  The housing is configured in a rectangular parallelepiped shape, and at least one side surface thereof is fitted with at least one convex protrusion and / or concave protrusion provided on at least one side surface of the other housing, and these housings are connected to each other. It is also preferable to have at least one concave protrusion and / or convex protrusion. Since a plurality of housings can be freely combined and integrated, an applied battery having a desired voltage and current capacity can be obtained as a whole.

  It is also preferable to further include a water injection pipe having a tip protruding from the housing and an external lead-out lead wire outlet formed in the housing.

  Further, according to the present invention, a plurality of the above-described applied batteries are arranged in parallel, and a plurality of water is disposed in which the tips of the plurality of water injection pipes of the plurality of applied batteries are respectively engaged in the plurality of discharge ports. There is provided an emergency power supply device including a tank and a pressing member that simultaneously presses down a plurality of water tanks and allows a closing film formed in advance in a plurality of discharge ports to be broken by a tip of a water injection pipe.

  Since the liquid from the plurality of water tanks can be simultaneously injected into the plurality of applied batteries simply by pressing down the pressing member, the emergency power supply device can be easily and quickly operated in an emergency.

  It is preferable to further include a push-down preventing member that can be removed and prevents the plurality of water tanks from being pushed down. By providing such a push-down preventing member, it is possible to prevent inconvenience that the emergency power supply device is erroneously operated.

  According to the present invention, a salt-containing cloth is provided in close contact with the carbonized cloth, a paper sheet having water absorption is provided in close contact with the salt-containing cloth, and the paper sheet is formed of a material having a high ionization tendency. In addition, since the metal plate is provided in close contact, the battery can be operated only by a small amount of liquid coming into contact with the paper sheet. Further, since the carbonized cloth, the positive electrode lead electrode, the salt-containing cloth, the paper sheet, the metal plate, and the negative electrode lead electrode are pressure-bonded to each other by the shrinkable cover member, the distance between the negative electrode and the positive electrode can be kept substantially constant. . Furthermore, the attachment of the shrink cover member enables the electrical connection between the carbonized cloth and the positive electrode lead electrode and the electrical connection between the metal plate and the negative electrode lead electrode, and this connection operation can be performed only by attaching the shrink cover member. Since it can be carried out reliably, the work process becomes very easy and the manufacturing cost is also low. As the salt-containing cloth, a single cloth having two or more layers of woven cotton cloth containing salt is used, so that the initial voltage and the initial current are significantly increased. In addition, the decrease in voltage and current after elapse of time is very small.

  A carbonized cloth 14 constituting a positive electrode is laminated in close contact with the positive electrode support plate 11 to which the positive electrode lead electrode 12 is fixed. More specifically, as shown in FIG. 2 (B), the carbonized cloth 14 is closely attached to the positive electrode support plate 11 and is wound around the vertical direction thereof. The carbonized cloth 14 used in this embodiment is a woven cloth, a knitted cloth, a woven or knitted cloth or a non-woven cloth made of cellulosic fiber yarns, and a woven cloth, a knitted cloth formed by heating carbonization thereof, A woven or knitted fabric or non-woven fabric, provided by Shin Nippon Tex Co., Ltd. This carbonized cloth 14 is not woven from rigid carbon fibers, but the cellulose fiber yarn itself, which is the starting material before carbonization firing, is soft and has a free direction. It has a very good electrical conductivity, dielectric properties, thermal conductivity and compressive strength not only in the plane direction but also in the thickness direction because it is sufficiently blended in the thickness direction. .

  A salt-containing cloth 15 is laminated in close contact with the carbonized cloth 14 constituting the positive electrode. More specifically, as shown in FIG. 2 (C), the salt-containing cloth 15 is closely attached to the carbonized cloth 14 and is wound around the vertical direction thereof. In this embodiment, the salt-containing cloth 15 is configured by impregnating a degreased cloth with saturated saline and drying, and when it is wet, the salt is eluted and functions as an electrolyte medium. In particular, in the present embodiment, the salt-containing cloth 15 is composed of a single cloth containing two or more layers of woven cotton cloth containing salt, as will be described later.

  A paper sheet 16 having water absorbability is closely adhered to the salt-containing cloth 15. More specifically, as shown in FIG. 2 (D), the paper sheet 16 is closely attached to the salt-containing cloth 15 and is wound around its lateral direction. This paper sheet 16 is a paper sheet made of natural pulp having a density of 1% or less, and the liquid that has been poured and slightly accumulated at the bottom of the housing is sucked up by capillary action to wet the entire salt-containing cloth 15, and the cloth The salt-containing cloth 15 and the paper sheet 16 function as an electrolyte medium between the positive electrode and the negative electrode, as will be described later.

  On the paper sheet 16, a metal plate 17 made of a magnesium material constituting the negative electrode is closely adhered and laminated. More specifically, as shown in FIG. 2 (E), a pair of tabular metal plates 17 made of magnesium material are stacked in close contact with each other on both sides of a paper sheet 16.

  As the metal plate 17, various materials such as aluminum and lithium can be applied in addition to magnesium as long as the material has a higher ionization tendency than the carbonized cloth 14 as the positive electrode. Moreover, the shape is not limited to a flat plate. Furthermore, only one sheet of the paper sheet 16 may be adhered and laminated.

  A negative electrode lead electrode 18 is attached to each metal plate 17. In the present embodiment, as the negative electrode extraction electrode 18, for example, a rivet made of a conductive material such as copper is inserted into the metal plate 17 and fixed. As shown in FIG. 2E, one end of a negative electrode lead wire 19 is electrically connected to each negative electrode lead electrode 18 by soldering.

  Although not shown in FIG. 2 (E), the positive electrode support plate 11, the positive electrode extraction electrode 12, the carbonized cloth 14, the salt-containing cloth 15, the paper sheet 16, the pair of metal plates 17 and the negative electrode extraction electrode described above. The laminated body which laminated | stacked 18 mutually is temporarily fixed with a tape. Thereafter, the temporarily-bonded laminate is inserted into the heat-shrinkable tube and heated to shrink the heat-shrinkable tube.

  As a result, as shown in FIG. 2 (F), the cell 10 is obtained in which the entire temporary fixing laminate is firmly crimped and fixed inside by the shrinkable cover member 20. The shrinkable cover member 20 firmly presses and fixes the positive electrode support plate 11, the positive electrode extraction electrode 12, the carbonized cloth 14, the salt-containing cloth 15, the paper sheet 16, the pair of metal plates 17 and the negative electrode extraction electrode 18 to each other. The distance between the negative electrode and the positive electrode can be kept substantially constant. Further, since the carbonized cloth 14 and the positive electrode lead-out electrode 12 can be electrically connected by the attachment of the shrinkable cover member 20, and the connecting operation can be reliably carried out only by attaching the shrinkable cover member 20, the work process. Is very easy and the manufacturing cost is low.

  FIG. 4 shows the relationship between the electrode area and voltage and current in such a cell 10, and FIG. 5 shows the relationship between the number of extraction electrodes attached to, for example, the negative electrode, voltage and current in the cell 10. As shown in FIG. 4, even if the electrode area is changed, the voltage characteristic and the current characteristic do not change, but when the number of extraction electrodes attached to the negative electrode or the positive electrode is changed, the current characteristic changes greatly.

  One applied battery of the present embodiment is configured by connecting a plurality of the cells 10 described above and accommodating them in a housing. FIG. 5 shows the appearance of this applied battery. The housing 50 is formed by molding a plastic material into a rectangular parallelepiped shape, and includes a box 51 having an upper surface opened and a lid 52 for closing the upper surface. Yes.

  One side surface 51a of the box 51 is provided with a projection 53a having a concave cross section and a projection 54a having a convex cross section, and the side surface 51b on the opposite side is provided with a projection 53b having a concave cross section and a convex shape. Projection 54b. The concave protrusion 53a and the convex protrusion 54a or the concave protrusion 53b and the convex protrusion 54b are configured to be fitted to the convex protrusion and the concave protrusion in another housing, respectively. By performing such fitting, a plurality of housings can be connected to each other to form a plurality of applied battery arrays.

  The lid body 52 has a through hole 52 a into which the water injection pipe 55 is inserted and a through hole 52 b through which the positive lead wire 56 a and the negative lead wire 56 b are inserted. The through hole 52 a passes through the water injection pipe 55. The gap is later sealed with an adhesive or the like, and the through hole 52b is sealed with an adhesive or the like after passing through the positive lead wire 56a and the negative lead wire 56b. In this embodiment, the water injection pipe 55 has a projecting tip that is inclined and opened, and has a sharp tip.

  By closing the opening of the box 51 with the lid 52 and sealing with an adhesive, the housing 50 becomes watertight except for the water injection pipe 55. In addition, although the dimension of the housing 50 is suitably selected according to the dimension and the number of the cells 10 accommodated therein, in the present embodiment, for example, the length is set to 85 mm, width 25 mm, and height 60 mm. The shape of the housing is not limited to a rectangular parallelepiped shape, and may be a cylindrical shape, a cone shape, a spherical shape, or any other shape.

  FIG. 6 shows a plurality of cells accommodated in the housing 50 and the connection state, and FIG. 7 illustrates the connection state of FIG. 6 with a wiring diagram. A plurality (eight in this case) of cells 10 are arranged so as to overlap each other, and the positive electrode lead wire and the negative electrode lead wire of each cell are connected and soldered so as to be connected in parallel and / or in series. The connection state of the positive electrode lead wire and the negative electrode lead wire of each cell is not limited to this example, and various connection states can be applied as necessary. The number of cells 10 accommodated therein and the connection form are appropriately set according to the required voltage and current capacity. In the case of the connections shown in FIGS. 6 and 7, an output of 1.4 V × 4 = 5.6 V, 1160 mA can be obtained from one applied battery.

  As described above, in the present embodiment, as the salt-containing cloth 15, one cloth uses a multi-layer woven cotton cloth containing two or more layers containing salt, so that a very good voltage and current can be obtained. Characteristics can be obtained. This point will be described in detail below.

  The inventor of the present application measured the initial voltage and current characteristics of a plurality of samples in which the salt-containing cloth 15 was composed of a one-layer woven cotton cloth, a two-layer woven cotton cloth, and a three-layer woven cotton cloth, and the time course characteristics thereof. Furthermore, the voltage and current characteristics with respect to the salt-containing concentration of a plurality of samples in which the salt-containing cloth 15 was composed of a one-layer woven cotton cloth, a two-layer woven cotton cloth, and a three-layer woven cotton cloth were measured. The actually measured voltage and current values are the terminal voltage and terminal current values of the sample. As is well known, this terminal voltage corresponds to a value obtained by adding an electromotive voltage and a voltage drop due to an internal resistance.

  The configuration of each sample is the same as the configuration of the cell 10 described above. That is, as the positive electrode, a woven fabric, a knitted fabric, a woven fabric, or a nonwoven fabric made of cellulosic fibers provided by Shin Nippon Tex Co., Ltd. is used as a raw material fiber body, and this is a woven fabric, a knitted fabric obtained by heating carbonization. A carbonized cloth 14 of cloth, woven / knitted cloth or non-woven cloth was used. The dimension of each positive electrode is 20 mm x 50 mm. As the negative electrode, a flat metal plate 17 made of a magnesium material was used. The dimension of each negative electrode is 20 mm x 50 mm. As the salt-containing cloth 15, absorbent cotton cloth of 1 layer weave, 2 layer weave and 3 layer weave was used. Each cotton cloth is used by being saturated with saturated saline.

  8 to 13 show the measurement results. FIG. 8 shows the relationship between the initial voltage and the salt-containing concentration, FIG. 9 shows the relationship between the initial current and the salt-containing concentration, and FIG. 10 shows the case where the salt-containing concentration is 10%. FIG. 11 shows the relationship between the voltage with respect to the standing time when the salt-containing concentration is 20%, FIG. 12 shows the relationship with the current with respect to the standing time when the salt-containing concentration is 10%, and FIG. The relationship of the electric current with respect to the leaving time when the concentration is 20% is shown.

  As can be seen from FIGS. 8 and 9, the initial voltage and the initial current are significantly higher when the two-layer woven cotton cloth is used as the cotton cloth constituting the salt-containing cloth 15 than when the one-layer woven cotton cloth is used. It is even higher when a three-layer woven cotton cloth is used. Further, as can be seen from FIGS. 10 to 13, as the cotton constituting the salt-containing cloth 15, the use of the two-layer woven cotton cloth causes both the decrease in voltage and current after the passage of time, rather than the use of the one-layer woven cotton cloth. Smaller and even smaller when using a three-layer woven cotton cloth. Therefore, the use of the two-layer woven cotton cloth provides better electrical characteristics than the use of the one-layer woven cotton cloth, and the use of the three-layer woven cotton cloth provides further excellent electrical characteristics. In other words, it is desirable to use a multi-layer woven cotton cloth as the cotton cloth constituting the salt-containing cloth 15. By using a multi-layer woven cotton cloth, it is presumed that the electrical characteristics are improved because more salt components are contained in each layer.

  Further, as can be seen from FIGS. 8 and 9, in the salt-containing cloth 15 using a multi-layer woven cotton cloth, a sufficiently large initial voltage and initial current can be obtained if the salt-containing concentration is 5% or more. In this measurement example, measurement was performed only up to the case where the salt-containing concentration was 25%. However, since the initial voltage saturates when the salt-containing concentration is 15% or more, good characteristics are obtained even if it exceeds 25%. It can be inferred that it will be obtained. In addition, since the initial current increases as the salt-containing concentration increases, it can be expected that good characteristics can be obtained even if it exceeds 25%. Furthermore, as can be seen from FIGS. 10 to 13, in the salt-containing cloth 15 using the multi-layer woven cotton cloth, the voltage and current characteristics after a lapse of time are better when the salt-containing concentration is 20% than when the salt-containing concentration is 10%. Has been obtained. Therefore, it is understood that in the salt-containing cloth 15 using the multi-layer woven cotton cloth, good voltage and current characteristics can be obtained if the salt-containing concentration is 5% or more.

  Furthermore, this inventor measured about the rise voltage and electric current characteristic of the sample which made the cotton cloth which comprises the salt containing cloth 15 contain salt, and the sample which does not contain salt, and its time passage characteristic. The actually measured voltage and current values are the terminal voltage and terminal current values of the sample.

  The configuration of each sample is the same as the configuration of the cell 10 described above. That is, as the positive electrode, a woven fabric, a knitted fabric, a woven fabric, or a nonwoven fabric made of cellulosic fibers provided by Shin Nippon Tex Co., Ltd. is used as a raw material fiber body, and this is a woven fabric, a knitted fabric obtained by heating carbonization. A carbonized cloth 14 of cloth, woven / knitted cloth or non-woven cloth was used. The dimension of each positive electrode is 20 mm x 50 mm. As the negative electrode, a flat metal plate 17 made of a magnesium material was used. The dimension of each negative electrode is 20 mm x 50 mm. As the cotton cloth, a two-layered absorbent cotton cloth was used. A sample in which salt is contained in a cotton cloth is used by injecting 3 cc of 20% saline, and a sample in which no salt is contained in the cotton cloth is used by injecting 3 cc of tap water.

  14 to 17 show the measurement results. FIG. 14 shows the relationship between the voltage with respect to the rise time, FIG. 15 shows the relationship with the current with respect to the rise time, FIG. 16 shows the relationship with the voltage with respect to the standing time, and FIG. The relationship of the current with respect to is shown respectively.

  As can be seen from FIGS. 14 and 15, as the cotton cloth, by using a cotton cloth containing salt like the salt-containing cloth 15, both the voltage and current are larger than when using a cotton cloth not containing salt, The rise is much faster. Moreover, as can be seen from FIGS. 16 and 17, by using a cotton cloth containing salt as the cotton cloth, the decrease in voltage and current after the passage of time is smaller than when using a cotton cloth not containing salt. . Therefore, superior electrical characteristics can be obtained using salt-containing cotton cloth rather than using salt-free cotton cloth.

  In the present embodiment, the carbonized cloth 14 is a woven fabric, a knitted fabric, a woven or knitted fabric or a non-woven fabric made of cellulosic fibers provided by Shin Nippon Tex Co., Ltd., and this is heated carbon. Since a woven fabric, a knitted fabric, a woven / knitted fabric or a non-woven fabric is used, very good voltage and current characteristics can be obtained. This point will be described in detail below.

  The inventor of the present application relates to the initial voltage and current characteristics of a plurality of samples in which the carbonized cloth 14 is composed of the special carbonized cloth of the present invention and commercially available general carbonized cloths A and B, and the time course thereof. The characteristics were measured. Further, the voltage and current characteristics with respect to the salt-containing concentration of a plurality of samples in which the carbonized cloth 14 was composed of the special carbonized cloth of the present invention and commercially available general carbonized cloths A and B were measured. The actually measured voltage and current values are the terminal voltage and terminal current values of the sample.

  The configuration of each sample is the same as the configuration of the cell 10 described above. That is, as the positive electrode, a woven fabric, a knitted fabric, a woven fabric, or a nonwoven fabric made of cellulosic fibers provided by Shin Nippon Tex Co., Ltd. is used as a raw material fiber body, and this is a woven fabric, a knitted fabric obtained by heating carbonization. A carbonized cloth 14 of cloth, woven / knitted cloth or non-woven cloth was used. The dimension of each positive electrode is 20 mm x 50 mm. As the negative electrode, a flat metal plate 17 made of a magnesium material was used. The dimension of each negative electrode is 20 mm x 50 mm. As the salt-containing cloth 15, a two-layered absorbent cotton cloth is used, which is impregnated with saturated saline.

  18 to 23 show the measurement results. FIG. 18 shows the relationship between the initial voltage and the salt-containing concentration, FIG. 19 shows the relationship between the salt-containing concentration and the initial current, and FIG. 20 shows the case where the salt-containing concentration is 10%. FIG. 21 shows the relationship between the voltage with respect to the standing time when the salt-containing concentration is 20%, FIG. 22 shows the relationship with the current with respect to the standing time when the salt-containing concentration is 10%, and FIG. The relationship of the electric current with respect to the leaving time when the concentration is 20% is shown.

  As can be seen from FIGS. 18 and 19, by using the special carbonized cloth of the present invention as the carbonized cloth 14, rather than using commercially available general carbonized cloths A and B, the initial voltage and the initial current are increased. Both are significantly higher. Further, as can be seen from FIG. 20 to FIG. 23, as the carbonized cloth 14, after using the special carbonized cloth of the present invention rather than using commercially available general carbonized cloths A and B, after a lapse of time. The decrease in voltage and current of both is small. Therefore, by using the special carbonized cloth of the present invention, very excellent electrical characteristics can be obtained.

  As described above in detail, according to the present embodiment, in a state where the applied battery is not operated, liquid such as fresh water, salt water, sea water, or the like is not injected into the housing 50 and there is no liquid, so it is portable. And storage is very easy. In addition, since a reaction hardly occurs unless a liquid is injected, long-term storage is possible. When the application battery is operated, when a small amount (for example, 30 cc) of liquid such as tap water is injected into the housing 50 through the water injection pipe 55, the liquid slightly accumulated at the bottom of the housing 50 has water absorption. The entire salt-containing cloth 15 is wetted along the paper sheet 16, and the salt contained in the salt-containing cloth 15 is eluted into the liquid, so that the carbonized cloth in which the salt-containing cloth 15 and the paper sheet 16 are positive electrodes. 14 and a pair of metal plates 17 as a negative electrode function as an electrolyte medium. As a result, a discharge reaction due to hydrogen ions occurs around the pair of metal plates 17. On the other hand, the carbonized cloth 14 does not react with hydrogen ions, and electrons are discharged from the pair of metal plates 17 that are the negative electrodes from the salt-containing cloth 15 and paper. An electromotive force is generated through an attempt to move to the carbonized cloth 14 as the positive electrode through the sheet 16. In this way, the salt-containing cloth 15 is provided in close contact with the carbonized cloth 14, and the paper sheet 16 having water absorption is provided in close contact with the salt-containing cloth 15, and the paper sheet 16 has a high ionization tendency. Since the pair of metal plates 17 formed in (1) are provided in close contact with each other, a small amount of liquid can be operated as a battery only by contacting the paper sheet 16. When the electromotive force of the battery decreases, the electromotive force is restored by adding about 5 cc of liquid and pouring water. In addition, since the salt-containing cloth 15 is a multi-layer woven cotton cloth having two or more layers containing salt, a very high initial voltage and initial current can be obtained. In addition, the decrease in voltage and current after a long period of time is very small. Furthermore, as in this embodiment, by using a special carbonized cloth as the carbonized cloth 14, both the initial voltage and the initial current can be significantly increased, and the voltage and current are reduced after a long time. Both can be greatly reduced.

  Further, the positive electrode support plate 11, the positive electrode extraction electrode 12, the carbonized cloth 14, the salt-containing cloth 15, the paper sheet 16, the pair of metal plates 17 and the negative electrode extraction electrode 18 are firmly bonded to each other by the shrinkable cover member 20. Therefore, the distance between the negative electrode and the positive electrode can be kept substantially constant. Furthermore, since the carbonized cloth 14 and the positive electrode lead-out electrode 12 can be electrically connected by the attachment of the shrinkable cover member 20, and the connecting operation can be reliably performed only by attaching the shrinkable cover member 20, the work process Is very easy and the manufacturing cost is low.
