Abstract
The present disclosure describes, among other things, new layered molybdenum oxides for lithium ion battery cathodes from solid solutions of Li2MoO3 and LiCrO2. These materials display high energy density, good rate capability, great safety against oxygen release at charged state due mostly to their low voltage. Therefore, these materials have properties desirable for lithium ion battery cathodes.
