Abstract:
A nonaqueous electrolytic secondary cell produced at low cost and having a large capacity comprises a negative electrode having an active material mainly composed of a material that at least absorbs and releases lithium ions or metallic lithium, a positive electrode, and an electrolyte. The active material of the positive electrode is an oxide containing nickel, manganese, and cobalt, and the contents of the elements are substantial the same.
