Title:
リチウムイオン二次電池
Document Type and Number:
Japanese Patent JP5855897
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery in which Li deposition on electrodes is more surely prevented than possible before.SOLUTION: A solid electrolyte which conducts lithium ions such as LiVO, LiTiO, LiTiO, LiTiO, LiNbO, and/or LiTaOis dispersed in a cathode mixture material containing a cathode active material composed mainly of lithium cobalt composite oxide, etc. and/or in an anode mixture material containing a carbonaceous active material. As a result, Li deposition on electrodes is prevented, making it possible to obtain a lithium ion secondary battery featuring high cycle characteristics. Especially, its cycle characteristics at low temperature are extremely good.
