Abstract

(57)【要約】 【課題】 リチウム二次電池のエネルギー量を高め、か つサイクル寿命を高める。 【解決手段】 正極活物質、負極材料、非水電解質から なる非水二次電池に於いて、該正極活物質は、リチウム を含有する遷移金属酸化物であり、該負極材料としてケ イ素原子を含む化合物、電解質として(a)有機ポリマ ー、(b)非プロトン性液体及び(c)アンモニウム塩または アルカリ金属塩またはアルカリ土類金属塩を含むゲル電 解質を用いることを特徴とする非水二次電池。
PROBLEM TO BE SOLVED: To improve the energy capacity and cycle lifetime of a lithium secondary battery. SOLUTION: This nonaqueous secondary battery is formed of a positive electrode active material, a negative electrode material, and a nonaqueous electrolyte. A transmit metal oxide containing lithium is used for the positive electrode active material, and a compound containing silicon atom is used for the negative electrode material, and the gel electrolyte containing (a) organic polymer (b) non-proton liquid and (c) ammonium salt or alkaline metal salt or alkaline earth group metal salt is used for the electrolyte.
