NEGATIVE ELECTRODE FOR SECONDARY BATTERY WITH NON-AQUEOUS ELECTROLYTE

摘要

PURPOSE:To provide a negative electrode for non-aqueous electrolyte secondary battery excellent in the charging/discharging cyclic characteristics. CONSTITUTION:A non-aqueous electrolyte secondary battery includes a positive electrode 1 and a negative electrode 4 made chiefly from a metal powder, which can store and release Li. The surface of metal powder as the neg. electrode active substance of this battery is covered with another metal, which presents ample ductility. This suppresses occurrence of insufficient collection of electricity likely to be generated when the electrode is turned into particulates at charging and discharging, and a non-aqueous electrolyte secondary battery is obtained which excels in charging/discharging cyclic characteristics.
