NEGATIVE ELECTRODE AND NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery which can suppress deterioration of charging/discharging cycle and can realize high capacity and a long life. SOLUTION: The nonaqueous electrolyte battery includes a positive electrode which contains lithium composite oxide, a negative electrode which contains metal that can form an alloy together with lithium or an alloy of such metal and a conductive polymer, and a nonaqueous electrolyte interposed between the positive electrode and the negative electrode.
