Abstract:
Lithium rich and manganese rich lithium metal oxides are described that provide for excellent performance in lithium-based batteries. The specific compositions can be engineered within a specified range of compositions to provide desired performance characteristics. Selected compositions can provide high values of specific capacity with a reasonably high average voltage. Compositions of particular interest can be represented by the formula, xLi2MnO3.(1−x)LiNiu+ΔMnu−ΔCowAyO2. The compositions undergo significant first cycle irreversible changes, but the compositions cycle stably after the first cycle.
