摘要

The lithium ion storage battery has anode active material chosen from nickel-lithium-manganese oxide and derivatives of nickel-lithium-manganese oxide and provides lithium insertion-extraction potential over the capacity operating range. The lithium ion storage battery has anode active material chosen from nickel-lithium-manganese oxide (LiNi 0 . 5Mn 1 . 5O 4) and derivatives of nickel-lithium-manganese oxide and provides lithium insertion-extraction potential over the capacity operating range. The derivatives of nickel-lithium-manganese oxide are nickel-lithium-manganese oxide type (Li 1 - aNi 0 . 5 - bMn 1 . 5 - cO 4 - d) and (LiNi 0 . 5 - xMn 1 . 5 + xO 4 - d), where a, b, c, d and x are -0.1-0.1, and d is =0.1. The storage batter further has separator imbibed with liquid electrolyte containing salt with lithium ion.
