NON-AQUEOUS ELECTROLYTE BATTERY AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte battery in which degradation of the property such as capacity degradation in hot temperature storage is prevented and which is reliable by also suppressing generation of gas.

SOLUTION: This is a non-aqueous electrolyte battery that comprises a positive electrode having as an active material manganese oxide or lithium- contained compound oxide, a negative electrode having as an active material a substance that can store and release lithium or lithium alloy or lithium ion, and a lithium-ion conductive non-aqueous electrolyte. The above positive electrode and/or negative electrode are formed using a mixture of the active material and an acid anhydride.
