Definitions
- 0001 is an inexpensive and excellent high temperature qualitative electrical device, and an electrical device that uses it and is safe even at high temperature. It is widely used as a source of equipment such as cellphones and notebooks because of its high electricity and electricity consumption, which is represented by 002-tium secondary batteries and skis. It is important to maintain safety as the electric power consumption of the equipment further increases with the performance of the equipment.
- a poin-based polymer with a temperature of 2 to 3 degrees is used as the electrode between the positive electrode and the negative electrode.
- the synthetic resin of the battery is blocked at a temperature below the (normal heat generation) level of the battery, which increases the resistance of the battery and improves the battery integrity in the event of a fault.
- a melting point (P) may be applied in order to secure the “yat-down” effect.
- patent 3 uses an adhesive cloth
- patent 4 uses the cloth as a base
- patent 5 uses a PP (PP) cloth
- patent 6 uses a polyester cloth.
- the technique concerning the data using is disclosed.
- Patent 78 discloses a technique based on a cloth and having a composition containing a fusible poe. With this configuration, the porosity does not contract to a high temperature, and the porosity melts at temperatures above the pooh point, exhibiting a yak property.
- the porosity is soft in the above-configured battery, for example, a commonly used positive electrode using an inorganic oxide as the active material of a lithium battery is used in combination with a battery. Then, since the inorganic acid is very hard, when the positive electrode and the negative electrode are pressed against each other via the electrode, the organic acid of the positive electrode may penetrate through the electrode and come into contact with the negative electrode. There is a problem in securing reliability.
- Patent 9 in order to prevent the above-mentioned connection, It has been proposed to construct a data-containing composition. However, in this type of configuration, there is a problem in maintaining safety because it is not provided with a shut down function. Further, in the example shown in Patent 9, simple granular particles are used as the inorganic filler, but according to these discussions, this nundrite is easy to generate when thianmundrite is formed, which is composed of granular fine particles. There is a high possibility that it will penetrate into the interior, and it is not possible to secure sufficient reliability for the internal damage caused by dendrites.
- the example shown in Patent 9 does not use the inder for connecting the inorganic filler, while the example shown in the Patent uses the inorganic inder.
- this structure without bending it, when it is manufactured by winding it around a positive electrode and a negative electrode, it is usually composed of an inorganic filler. It is easy for cracks to occur, which can cause short circuits.
- problems such as the entanglement due to the deviation of the setter are remarkable.
- This patent discloses a structure in which a yatdown layer made of a cloth and a polite made of an inorganic filler is provided to ensure the yatdown function. According to this composition, the heat resistance of the setter can be secured and the yat down function can be imparted, but it is composed of the basic cloth and the inorganic filler.

- the second layer related to Ming Ta is to secure the yat down function. If the layer contains resin, when the temperature of the electron incorporating the bright metal reaches or exceeds the point, the melts and suppresses the electric reaction of the layer. , Cause down. On the other hand, if the above-mentioned layer contains resin, due to the increase in the number of the electrons incorporating the bright metal, will absorb the inside of the electron, and , By reducing the effective electrolysis present in the part of the , Yat down occurs. In addition, in the case of Mita, if the layer contained is, it does not cause the shutdown due to the curing of the setter, but the resin formed on the side of the setter forms a film and inhibits the conduction of ions.
- down may occur. It is likely that this kind of shutdown is likely to occur if there is a data layer containing on the data surface and the ratio on the data surface is high. In this case, it can be expected that the degree of downtime will be faster than that of the set.
- the second layer related to Mita has the function of setter, and mainly the function of preventing the contact by contact with the positive and negative electrodes, and the frequency is above 5 C. Therefore, the function is secured. That is, in the case where an electric element is normally used by the two-layer structure, when the positive electrode and the negative electrode are pressed through the setter to form an electrode, the positive electrode material penetrates the electrode and contacts the negative electrode. It is possible to prevent the growth of In addition, when the temperature of the electrochemical cell becomes high, the two layers can suppress the contraction of the setter and maintain its shape. It is also possible to prevent tangles due to touch. In addition,
- the term "on 5 C” as used herein means that at least 5 C and the like are not found.
- the degree of frequency is not particularly limited.
- at least one of the ta and bilayers contains a child. Since at least one of the second and second layers contains a child, the path of the positive electrode in the set, that is, the size of the positive electrode in the second layer increases. Therefore, even if dendrites are generated, it is difficult for the dendrites to reach the positive electrode from the negative electrode, and the reliability of the internal contacts caused by the dendrites can be improved.
- the two-layer when the two-layer contains children, this child can also serve as an irritant at a temperature of 5 C or higher, and a part of the illus included in the two-layer can be composed of children.

- the property of increasing with temperature rise (below, there is a case where is heated more than the time when appears, is absorbed by the inside of the electrochemical cell and becomes large.
- the flowable electrolysis decreases and the electrons are left in a loose state, which causes the breakdown of the electrons and ensures the integrity of the electrochemical cells.
- the swelling further promotes the above and further suppresses the response of the electrons, so that it is possible to further improve the integrity after the shut down.
- 003 begins to exhibit thermal expansion, preferably above 75C. This is because by setting the degree of thermal expansion to 75 C or above, it is possible to set the value to significantly increase and the resistance of the battery rises (that is, loose shut down) to about 8 OC or above. . On the other hand, the higher the limit of thermal expansion, the higher the settling down of the setter, so in order to set the settling down to 3C below, start to show Is preferred and below C is more preferred. If the degree of thermal conductivity is too high, it may not be possible to sufficiently suppress the response of the battery quality, and the effect of improving the integrity of the electron may not be secured sufficiently.If the degree of thermal expansion is too low, it is usually The sq m in the child (approx. 7 C) can be too low.
- the electrolysis which is absorbed by 003 (25C) is defined by () which represents

In addition, in the following (3) to (9), it is assumed that the amount outside the electrolysis at 25 C to 2 C can be ignored.

Physically, and It is preferable that the diameter is .about.2 4. If the diameter of the resin is too small, the size of the particles becomes smaller, and the ion spacing may become longer, resulting in a decrease in the properties of the electrons. On the other hand, if the particle size is too large, the thickness of the electrode layer becomes large, which is not preferable because it leads to a decrease in the electron density.
