Title:
Nonaqueous electrolyte secondary battery
Document Type and Number:
Japanese Patent JP5934532
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a secondary battery having high capacity and excellent cycle charge/discharge characteristics.SOLUTION: In a battery in which aluminum or an aluminum alloy is used as a current collector of a positive electrode, the positive electrode whose material surface is covered with a composition for a polymer solid electrolyte containing a polyether copolymer and an electrolyte salt compound contains a compound having a phenol structure with both of ortho positions substituted with a tert-butyl group, and a secondary battery having high capacity and excellent cycle charge/discharge characteristics is obtained by employing the positive electrode subjected to heat treatment for the secondary battery before application of a potential even if a fluorine-containing organic supporting electrolyte is used.
