Positive electrode active material and non-aqueous electrolyte secondary battery containing the same
The present invention discloses a non-aqueous electrolyte secondary battery comprising: a negative electrode containing metallic lithium or a substance at least capable of absorbing/desorbing lithium ion; a separator; a positive electrode; and an electrolyte, wherein the active material for the positive electrode comprises an oxide containing nickel element and manganese element in substantially the same atomic ratios. The non-aqueous electrolyte secondary battery thus fabricated is low cost in construction and has a high capacity.
