Abstract

A nonaqueous electrolyte battery having improved characteristics under a heavy load environment and incorporating nonaqueous electrolytic solution which contains vinylene carbonate in a proper quantity to improve conductivity of the nonaqueous electrolytic solution so that doping/dedoping of lithium ions is performed smoothly and, therefore, the internal resistance is decreased. Hence it follows that the initial capacity of the battery is enlarged and satisfactory heavy load characteristics are realized.
