摘要： 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.
