Document Type and Number:
Japanese Patent JP5626531
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery which has a basic performance as a battery, and has a high capacity and excellent charge-discharge characteristics and excellent safety and reliability even when a silicon-based negative electrode material is used.SOLUTION: The nonaqueous electrolyte secondary battery, which has a basic performance as a battery, and has a high capacity and excellent charge-discharge characteristics and excellent safety and reliability, is obtained by incorporating a conductive silicon complex and a fibrous carbon compound into a negative electrode, and by suitably selecting specific polyether copolymer and electrolyte salt compound as an electrolyte, and by holding it with a positive electrode.
