The present invention relates to a method for manufacturing a battery.

2. Description of the Related Art In recent years, the production of batteries has been rapidly increasing with the development of portable electronic devices, and the demand for backup batteries has been steadily increasing due to the spread of personal computers and word processors. As batteries used in these applications, the demand for rechargeable and long-life rechargeable batteries is rapidly increasing, and lithium is used as an electromotive substance, and carbon or lithium capable of absorbing lithium by intercalation is used. Attention has been paid to lithium secondary batteries using chalcogen compounds.

However, lithium has an extremely high activity with respect to water, and has problems such as ignition due to liquid leakage or inactivation of lithium due to invasion of air or moisture, and the sealing thereof is required to have a high degree of sealing. . As means for reducing such troubles, the electrolyte filled between the positive electrode and the negative electrode is made non-fluidized by using a gelling agent or the like to prevent liquid leakage. As a result, the housing for covering the battery element does not require rigidity for maintaining its shape, and a flexible film can be used, thereby reducing the size of the secondary battery and increasing the degree of freedom in shape. In addition, a thin secondary battery using a non-fluid electrolyte has attracted attention because of its advantages such as suppression of generation of dentite, which is a major problem as a lithium battery.

However, in order to form a secondary battery having a high capacity and good rate characteristics, it is necessary to laminate a large number of flat and thin positive and negative electrode materials. For example, as shown in FIG. 1, the positive electrode material 1 or the negative electrode material 2 is laminated on the surface of the current collector 5 to form a flat electrode material, and as shown in FIG. Attempts have been made to laminate a plurality of sheets via the fluid electrolyte layer 3 to form a large-capacity battery. In such a case, the cathode material 1 cut to a predetermined size, the spacer 3 impregnated with a non-fluid electrolyte sheet or a non-fluid electrolyte, and the negative electrode material 2 need to be superposed at correct positions.

[0005] In particular, as shown in Fig. 4, when manufacturing a laminated body having different sizes and shapes of the positive electrode material 1 and the negative electrode material 2, they cannot be handled in a long shape, and the positive electrode material and the negative electrode material are made into sheets. After cutting into leaves, a process of transporting and stacking each leaf is required. However, thin sheets cut into small pieces are displaced during conveyance, and it is difficult to stack them accurately. The position can be corrected by providing a position detection device and a correction device in the laminating mechanism within a small range of displacement, but if the displacement is large, or if it is dropped from the transport mechanism during transport. Has a problem that the correction device cannot cope with it. Therefore, development of a mechanism for transporting a thin sheet without displacement is desired.

The thickness is appropriately selected, but is preferably 1 to 30 μm. If the thickness is too small, the mechanical strength becomes weak, which causes a problem in production. If it is too thick, the capacity of the battery as a whole decreases.

As the positive electrode material forming the positive electrode material, either an inorganic compound or an organic compound can be used as long as it can occlude and release lithium ions. Examples of the inorganic compound include a transition metal oxide, a composite oxide of lithium and a transition metal, and a chalcogen compound such as a transition metal sulfide.

Further, a mixture of the above-mentioned polymers and the like, a modified product, a derivative, a random copolymer, an alternating copolymer, a graft copolymer, a block copolymer and the like can also be used.

The electrode may contain additives, such as conductive materials and reinforcing materials, which exhibit various functions, powders, fillers, and the like, if necessary. As a method of forming the positive electrode material and the negative electrode material on the current collector, for example, a powdery electrode material is mixed with a solvent together with a binder, a ball mill, a sand mill,
A method in which a dispersion paint is formed by a twin-screw kneader or the like and applied to a current collector and dried is suitably performed. In this case, the type of the solvent used is not particularly limited as long as it is inert to the electrode material and can dissolve the binder.
For example, any of commonly used inorganic and organic solvents such as N-methylpyrrolidone can be used.

Further, the electrode material layer can be formed by a method in which the electrode material is mixed with a binder, heated and softened by heating, and then pressed or sprayed onto the current collector. Further, it can be formed by firing the electrode material alone on the current collector.

Examples thereof include sulfur compounds such as sulfolane and nitriles such as acetonitrile.

A gel electrolyte can be used for the non-fluid electrolyte layer 3. The gel electrolyte is mainly composed of an electrolyte containing a supporting electrolyte and a solvent, and contains a polymer for gelation, and the electrolyte is held in a polymer network, so that the fluidity as a whole is significantly reduced. Things. Characteristics such as ionic conductivity are similar to those of a normal electrolytic solution, but fluidity, volatility, etc. are significantly suppressed, and safety is enhanced.

In order to form a gel electrolyte layer, there can be mentioned a method of using an electrolyte material containing a monomer (polymerizable gelling agent) and polymerizing the same to form a polymer. Polymers capable of performing such a reaction include those produced by polycondensation of polyester, polyamide, polycarbonate, polyimide, etc., those produced by polyaddition such as polyurethane, polyurea, etc., and acrylics such as polymethyl methacrylate. Derivative polymers and polyvinyl acetates such as polyvinyl acetate and polyvinyl chloride are also produced by addition polymerization, etc., but the polymerization is easy to control and the high polymerization produced by addition polymerization does not generate by-products during polymerization. It is desirable to use molecules. In particular, a method of polymerizing a monomer having a reactive unsaturated group is preferable because of its high productivity.

Examples of such a monomer having a reactive unsaturated group include acrylic acid, methyl acrylate, ethyl acrylate, ethoxyethyl acrylate, methoxyethyl acrylate, ethoxyethoxyethyl acrylate, polyethylene glycol monoacrylate, and ethoxyethyl methacrylate. , Methoxyethyl methacrylate, ethoxyethoxyethyl methacrylate, and the like. As a method of polymerizing these monomers, there is a method using heat, ultraviolet rays, an electron beam or the like, but a method using ultraviolet rays or heat is effective from the viewpoint of high productivity.
In this case, in order to make the reaction proceed effectively, a polymerization initiator that reacts with ultraviolet light may be added to the electrolytic solution. In addition, at the time of thermal polymerization, a polymerization initiator may be added to control the reaction.

In order to form a gel electrolyte layer, a method of using an electrolyte material containing a polymer which can be gelled by cooling and cooling the polymer to room temperature can also be adopted. In this case, as the polymer that can be used, any polymer can be used as long as it forms a gel with respect to an electrolytic solution and is stable as a battery material.

Can be used. Specifically, a microporous film, a nonwoven fabric, a woven fabric, or the like formed using a synthetic resin such as polyolefin can be used.

The secondary battery manufactured by the apparatus of the present invention is obtained by cutting a thin plate-shaped positive electrode material 1 and a negative electrode material 2 into predetermined shapes and dimensions, forming small leaf bodies, and then laminating. Further, between the positive electrode material 1 and the negative electrode material 2 depending on the purpose,
A non-fluid electrolyte sheet, a spacer, a spacer impregnated with a non-fluid electrolyte or a precursor thereof, and the like are interposed. In the present invention, in addition to the positive electrode material 1 and the negative electrode material 2, spacers used in conjunction therewith, including thin sheets such as non-fluid electrolyte sheets, etc., are referred to as electrode materials. Alternatively, a laminate of two or more is referred to as an electrode material.

The battery element 4 composed of the positive electrode material 1, the negative electrode material 2, and the non-fluid electrolyte layer 3 can have a structure suitable for the purpose. For example, as shown in FIG. 1, a positive electrode material composition is laminated on a current collector 5 to obtain a plate-shaped positive electrode material 1. The negative electrode material 2 is formed into a plate shape by the same method, and the positive electrode material 1 and the negative electrode material 2 formed into a plate shape are alternately laminated via a non-fluid electrolyte layer 3 as shown in FIG. Forming a cell,
A large capacity battery can be obtained by laminating this so that the positive electrode side faces the positive electrode side and the negative electrode side faces the negative electrode side. When electrode materials are formed on both surfaces of the current collector 5, the positive electrode material 1 and the negative electrode material 2 can be alternately laminated via the non-fluid electrolyte 3.

When the electrode material is quadrangular, a tab 5a protruding from the positive electrode material 1 is formed on one side of one side of the electrode material as shown in FIG. A tab 5b is formed on the opposite side of the same side to form a protruding tab 5a.
The tabs 5b and the tabs 5b are vertically connected to form a positive electrode and a negative electrode current lead-out terminal, whereby a large-capacity battery element 4 can be obtained. It is desirable that the size of the positive electrode material 1 and that of the negative electrode material 2 be changed as shown in FIG. In general, the spacer is stacked on the positive electrode material 1 or the negative electrode material 2 from the viewpoint of handling, and is handled in a state of being stacked on the positive electrode material 1 or the negative electrode material 2.

The positive electrode material 1 and the negative electrode material 2 are laminated after the electrolytic solution is applied. The electrolytic solution is applied by adding a precursor of a non-fluid electrolytic solution to at least one of the positive electrode material 1 and the negative electrode material 2 and laminating the electrode material and, if necessary, interposing a spacer between them to form a precursor. Is preferable. Examples of the precursor include an electrolyte containing the monomer and an electrolyte containing a polymer that can be gelled by cooling.

The system for stacking the cathode material and the spacer is not limited and can be arbitrarily configured according to the purpose. As shown in FIG.

Reference numeral 12 denotes a feeding mechanism for feeding the stacked battery elements 4 to the next step.

Thus, in the present invention, the transport of the electrode material to be laminated is performed using a comb-shaped electrode material support. As an example, as shown in FIG.
, And an electrode material support rod 17a, 17b, 17c,... Which holds the electrode material S. Are provided in parallel, and one end thereof is connected by a connecting rod 18. Also, a plurality of electrode material support rods 19a, 19b, 19c are arranged in parallel on the second electrode material support member 16, and are connected to the first electrode material support member 15 on the side opposite to the mounting position of the connection rod 18. A rod 20 is provided to support electrode members 19a, 19b, 19
c are connected.

The electrode support rod 1 of the first electrode support 15
The interval between 7a, 17b and 17c is the second electrode material support 1
6 is larger than the width of the electrode material supporting rods 19a, 19b and 19c, and the electrode material supporting rods 1
9a, 19b, 19c is the first electrode material support 1
5 is larger than the width of the electrode material supporting rods 17a, 17b, 17c. Therefore, as shown in FIG. 9, the first electrode material support 15 and the second electrode material support 16 can bite each other, and can pass each other up and down.

The upper surfaces of the electrode material support rods 17a, 17b, and 17c of the first electrode material support 15 and the upper surfaces of the electrode material support rods 19a, 19b, and 19c of the second electrode material support 16 are small. A hole 21 is formed and connected to a pump (not shown) so as to suck air, so that when the electrode material S is placed on the electrode material supporting rods 17 and 19,
It is desirable to suck and hold this. By holding by suction, a thin sheet-shaped body can be stably conveyed without causing a positional shift. Particularly, an electrode material impregnated with an electrolytic solution is subjected to steps such as application, drying, and consolidation. Although it is easy for curl to occur and lamination becomes difficult, this can be maintained flat and laminated accurately.

The thus configured electrode material support 15,
As shown in FIG. 9, reference numerals 16 are alternately arranged in the transport direction of the electrode material S, and each of the electrode material supports 15, 16 is configured to be able to move up and down, advance and retreat. When the electrode material S is transported using such a transport device, the following method is used. In the first method, as shown in FIG. 10, after the first electrode material support 15 on which the electrode material S is placed rises to the point a, it moves forward in the transport direction and is located at the point b. Next, when the first electrode material support 15 descends and is located at the point c, the electrode material S is transferred to the second electrode material support 16. Subsequently, the second electrode material support 16 moves up, moves forward, descends, and retreats, and the electrode material S is conveyed by repeating these steps sequentially.

The apparatus of the present invention conveys the electrode material by such an operation. Therefore, ascending upward from below the electrode material support holding the electrode material means relatively rising, and as the electrode material support holding the electrode material descends, the adjacent electrode material support rises. Is included. As a second method, it can be performed by the operation of FIG. That is, the first electrode material support 15
Instead, the second electrode material support 16 descends to the point a, then retreats to the opposite side in the transport direction, is located at the point b, and then rises and moves to the point c, thereby displacing the electrode material S. After being received on the upper surface of the second electrode material support 16, it proceeds to point d and returns to point e. Then, the second electrode material support 1
The electrode material support 15 (not shown) in front of 6 performs the same operation, so that the electrode material S can be transported forward.

When changing the traveling direction at the point p shown in FIG. 6, it can be performed by the following mechanism.
That is, as shown in FIG. 12, a first transport path 25 for feeding the electrode material S and a second transport path 26 for transporting the electrode material S while changing the traveling direction are provided, and the end of the first transport path is provided. T and the starting end R of the second transport path 26 are respectively connected to the first electrode material holder 1.
5 so that the second transport path 26 is located at an inner corner of the corner formed by the first transport path 25 and the second transport path 26 so as to face the second transport path 25.
Are provided.

The second electrode material support 16 is rotatably supported by a rotating shaft 27.
By turning, 6 can be engaged with both the first electrode material holder 15 of the first transport path and the first electrode material holder 15 of the second transport path. When the traveling direction of the electrode material S is changed by such a mechanism, when the electrode material S is fed to the end of the first transport path 25, the second electrode material support 16 holds the electrode material S. 1 electrode material support 1
5 (corresponding to the position b in FIG. 12), and the electrode material S is received by the second electrode material support 16,
Next, it rises above the first electrode material support 15.

The second electrode material support member 16 which has received and raised the electrode material S is rotated clockwise by 90 ° in the figure to rotate the first electrode material support member 16 at the start end of the second transport path 26. After descending after being located above the support 15 and descending below the first electrode material support 15 to pass the electrode material S to the first electrode material support 15 at the beginning of the second transport path, The second electrode material support 16 rotates 90 degrees counterclockwise, moves below the first electrode material support 15 at the end of the first transport path, and stops. The thus transported negative electrode material 2, separator 3, and positive electrode material 1 are stacked to form a battery element 4, and the formed battery element 4 is fed to the next step such as polymerization of a polymerizable gelling agent. A secondary battery is formed. It is needless to say that the stacked battery elements 4 can be fed by using the transport device of the present invention.
