SECONDARY BATTERY WITH NONAQUEOUS ELECTROLYTE

摘要

PROBLEM TO BE SOLVED: To improve charge and discharge cycle characteristics and storage characteristic. SOLUTION: Lithium, lithium alloy, or lithium-titanium oxide of spinel type structure is used as an active material for a negative electrode 5. An active material containing lithium-manganese oxide i4/3 Mn5/3 O4 is used as a positive electrode. LiN(CF3 SO2 )2 is used as electrolyte. A solvent used contains more than one ingredients including ethylene carbonate.
