Title:
NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP3703667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a coin type (button type) non-aqueous electrolyte secondary battery that is durable at a reflow temperature.
SOLUTION: (1) An electrode and member having a heat resistance were selected. (2) By reducing fine powder, electrode active substance was made more thermally stable. (3) By heat-treating the electrode at 200°C to 450°C, the degradation of battery characteristics was inhibited. (4) In the selection of electrolytic solution and thermo-stable member, the optimum combination was investigated. By the optimum combination of these technologies, a coin type (button type) non-aqueous electrolyte secondary battery that is durable at a reflow temperature was prepared.
