ACTIVE MATERIAL FOR ELECTRODE FOR NONAQUEOUS-ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS-ELECTROLYTE SECONDARY BATTERY

摘要

An active material for electrodes for nonaqueous-electrolyte secondary batteries which inhibits deterioration of life characteristics is provided by deactivating the active sites of an active material having a plurality of micropores. The active material for electrodes for nonaqueous-electrolyte secondary batteries is characterized by having undergone a surface treatment with an antioxidant. An electrode for nonaqueous-electrolyte secondary batteries which has excellent life characteristics, etc. is obtained by using a slurry composition for electrodes for nonaqueous-electrolyte secondary batteries, the composition comprising the active material, a binder, and a solvent.
