内が収り、出しべく（壜るとめう問題もあった。For example, conventional materials for battery cases that house batteries (e.g., Japanese Utility Model Application Publication No. 160465/1983) include thermoplastic resins such as ABS (acrylonitrile styrene butadiene-substrate), PS (bo-1-nostyrene), PC (polycarbonate) etc. were used. A used here
For resins such as BS%PS, each heat resistant temperature (UL temperature index: Underwriters Labora
The maximum continuous operating temperature specified by the United States is 60 to 80°C, which is lower than the maximum battery operating temperature.
The quality of the case, which is originally intended to protect the battery, is insufficient. In addition, even PC, which is generally known as engineering plastic, has a temperature of 120°C, which is difficult to say from a safety standpoint.Furthermore, in the temperature-rising solder bath test, which is a very severe battery case safety test, conventional synthetic Resin materials cannot at all play the role of protecting the stored battery. Furthermore, when a battery using an organic electrolyte is used under abnormal conditions such as a short circuit or high temperature, the safety valve is activated and the organic electrolyte inside the battery leaks and adheres to the battery case housing the battery. Here, the battery case is ABS, PS, PC-

It exhibits the properties of not melting even at a temperature of 1000, having heat resistance, and being insoluble and stable even in organic electrolytes, and when used in a battery case, it can impart the above properties to the battery case. In particular, when organic flame retardants or inorganic flame retardants are added to resins, they (1) capture free radicals and suppress the chain reaction of decomposition of thermosetting resins that progresses through a radical mechanism (2) ) Preventing the diffusion of oxygen or air to the surface of combustible gases and polymers (blocking effect) (3) Using thermosetting resins with an action mechanism that generates inert gas that dilutes flammable pyrolysis gases. The increase in flame retardancy of the battery case can be measured.
