US Classification:

429221, 429224, 429223

Abstract:

This invention relates to positive electrode materials for electrochemical cells and batteries. It relates, in particular, to electrode precursor materials comprising manganese ions and to methods for fabricating lithium-metal-oxide electrode materials and structures using the precursor materials, notably for lithium cells and batteries. More specifically, the invention relates to lithium-metal-oxide electrode materials with layered-type structures, spinel-type structures, combinations thereof and modifications thereof, notably those with imperfections, such as stacking faults and dislocations. The invention extends to include lithium-metal-oxide electrode materials with modified surfaces to protect the electrode materials from highly oxidizing potentials in the cells and from other undesirable effects, such as electrolyte oxidation, oxygen loss and/or dissolution.

International Classification:

H01M 4/505

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. These stabilized materials are attractive 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, as defined by the phase diagram and compositional space of each system.
