いる。Organic electrolyte batteries, which use light metals such as lithium and magnesium as negative electrode active materials, carbon fluoride, copper sulfide silver chromate, manganese dioxide, etc. as positive electrode active materials, and use a non-aqueous organic electrolyte, are batteries with high energy density. Among them, demand for lithium batteries is rapidly increasing due to the remarkable spread of small and portable electronic devices.

要となっている。BACKGROUND ART With the spread of electronic devices, the environments and conditions in which they are used are becoming more diverse, and batteries that can be used even in special environments are becoming necessary. High-temperature environments are one of them, and as more and more electronic devices are used near engines, motors, or heat sources, there is a need for highly reliable batteries for use in these devices.

するなど様々か障害を起し、信頼性に欠けるものであっ
た。Conventional organic electrolyte batteries have a wider operating temperature range than other aqueous batteries, but due to the boiling point of the organic solvent used, the upper temperature range is generally 60 to 80°C. For this reason, when conventional batteries are used at temperatures above this temperature limit, the internal pressure of the battery increases, leading to deterioration in battery performance such as leakage. In addition, they suffered from various failures such as batteries exploding, making them unreliable.
また、使用温度範囲内ではあっても、高い温度側での長
期保存や長期使用は電池性能を劣化させるため、そのよ
うな使用にはあまシ適していなかった。Furthermore, even if the temperature is within the operating temperature range, long-term storage or long-term use at high temperatures degrades battery performance, so it is not suitable for such uses.

ぎるため、大規模碌発電システムを要し、特殊用途以外
に広く実用化されるに至ってい力い。A series of solid electrolyte batteries that use dispersion salt as an electrolyte have been developed as batteries for use at high temperatures, but these can only be used at high temperatures, and the operating temperature is too high, making it difficult to use them for large-scale power generation. system, and it has not been widely put into practical use other than for special purposes.
本発明の目的は、かかる従来の有機電解液および電解質
の欠点に対処する非水電解液を提供することにある。It is an object of the present invention to provide a nonaqueous electrolyte that addresses the drawbacks of such conventional organic electrolytes and electrolytes.

して適用可能であることを見出した。Silicone compounds such as silicone oil and silicone varnish are typical of these polymer compounds, and are known to have excellent heat resistance, chemical resistance, insulation properties, and the like. Therefore, the inventors attempted to apply a liquid polymer compound having siloxane as a main chain or main component as a solvent for battery electrolyte. There are various requirements for a battery electrolyte to be used as a solvent, but in particular it must be able to dissolve the electrolyte well and have high ion mobility in order to generate ion-conducting carriers. Therefore, no matter how good the heat resistance, chemical resistance, and insulation properties are, if the solubility in the electrolyte is low or the ion mobility is low, high ionic conductivity cannot be obtained and the electrolyte solvent cannot be used. It will not be suitable. The inventors discovered that this polymer compound can be electrolyzed by changing its molecular weight, terminal groups, and functional groups to appropriate amounts, or by forming a copolymer with other polymer compounds. It has been found that it can be used as a solvent for liquids.
