NONAQUEOUS ELECTROLYTIC SECONDARY BATTERY

摘要

PURPOSE: To improve continuous charge performance and discharge performance of a nonaqueous electrolytic secondary battery. CONSTITUTION: A nonaqueous electrolytic secondary battery has a negative electrode using lithium as an active material, a positive electrode using a manganese oxide containing lithium and boron as an active material, and a nonaqueous electrolyte comprising a solvent and a solute. The pore volume of the manganese oxide is specified to be not less than 0.040cc/g.
