Abstract
Cation-stabilized materials and compositions are described herein, which suppress the structural and electrochemical instability of lithium-metal-oxide spinel and lithiated lithium-metal-oxide spinel electrodes for lithium batteries, notably lithium-ion batteries. The lithium metal oxide electrode material comprises a disordered rock salt structure with partial lithiated-spinel character, wherein, for example, the disordered rock salt structure comprises a formula Li(M″M'″)O, which has the crystallographic formula: [LiM′″][M″M′″Li]Owherein 16c and 16d refer to the octahedral sites of the prototypic space group symmetry Fdm; M″ and M′″ are metal ions; 0<a≤0.5; and 0<b<0.5. These stabilized materials are useful as positive electrodes for lithium batteries in their own right or when used as a structural component to stabilize layered metal oxide electrode systems, such as a two-component layered-layered system or a multi-component layered-layered-spinel system.
