It is configured as follows. The electrolyte is mainly a mixture of propylene carbonate and 1,2-dimethoxyethane dissolved with lithium perchlorate, and the insulating packing is made of polypropylene, which has good chemical resistance so that it will not be affected by the organic electrolyte.

キングの熱酸化劣化が加速される。A mixed composition of polypropylene and polyethylene, or a copolymer resin of polypropylene and polyethylene, etc., were molded and used. However, polypropylene has the following drawbacks. In other words, polypropylene has tertiary carbon atoms and is susceptible to thermal oxidative deterioration. When manganese dioxide or copper oxide is used as the positive electrode active material of an organic electrolyte battery, organic 2+ ions such as Mn or Cu ionized in the electrolyte
The valent heavy metal ions come into contact with the insulating packing, and the catalytic action of these heavy metal ions accelerates thermal oxidative deterioration of the polypropylene insulating packing.

。As a result, the sealing effect of the insulating packing is reduced, and the organic '1ULl'l'l' liquid leaks from the interface between the sealing plate or the battery case and the insulating packing. ■If the battery is stored in a humid atmosphere, water will seep into the stain pond through the interface between the sealing plate or battery case and insulating packing. Lithium, which is an active material for the negative electrode, reacts with water as shown in the formula below, and hydrogen gas is generated, causing the battery to swell, increasing the distance between the battery's electrodes, and increasing the internal resistance of the battery. be.
