METHOD OF MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A method of manufacturing a nonaqueous electrolyte secondary battery includes: a kneading step of kneading a carbon-based negative electrode active material, a binder, and a sugar alcohol with each other to form a negative electrode mixture paste; and an application step of applying the negative electrode mixture paste to a negative electrode current collector to form a negative electrode mixture layer. The sugar alcohol is preferably mannitol, xylitol, sorbitol or maltitol in an amount of 0.1-7 weight percent of the carbon-based negative electrode active material. It is thus possible to obtain a nonaqueous electrolyte secondary battery, especially a lithium-ion battery, wherein the battery safety during overcharge is improved without increasing the battery resistance.
