NONAQUEOUS-SOLVENT TYPE ELECTRICITY STORAGE DEVICE

摘要

It is intended to provide an electric storage device that has excellent charging characteristics, particularly at a low temperature. Hence, provided is a nonaqueous solvent-based electric storage device containing as positive electrode active materials, at least one of a lithium nickel aluminum complex oxides and a spinel-type lithium manganese oxide active material having LiMn 2 O 4 as a basic structure, and lithium vanadium phosphate.
