摘要： The present invention provides a novel composition and method for preventing decomposition of one or more electrochemical cell components comprising an electrode having an active material, and an electrolyte. The method of the invention effectively blocks decomposition of a lithium metal oxide cathode active material, and particularly lithium manganese oxide (LMO, nominally LiMn O). Such decomposition is prevented by including in the cell a basic compound which forms an electron donor species in the electrolyte solution; and by neutralizing at least a portion of the acid by reacting the donor species with the hydrogen-containing acids thereby preventing decomposition of the lithium manganese oxide by the acid. The preservation of the lithium manganese oxide prevents degradation of other cell components by other mechanism.

摘要： The invention provides a novel method for making lithium mixed metal materials in electrochemical cells. The lithium mixed metal materials comrise lithium and aat least one other metal besides lithium. The invnetion involves the reaction of a metal compound, a phosphate compound, with a reducing agent to reduce the mettal and form a metal phosphate. The invention also includes methods of making lithium metal oxides involving reaction of a lithium compound, a metal oxide with a reducing agent.

摘要： The present invention provides for the preparation of an 'optimized' VPO4 phase or V-P-O/C precursor. The VPO4 precursor is an amorphous or nanocrystalline powder. The V-P-O/C precursor is amorphous in nature and contains finely divided and dispersed carbon. Throughout the specification it is understood that the VPO4 precursor and the V-P-O/C precursor materials can be used interchangeably to produce the final vanadium phosphates, with the V-P-O/C precursor material being the preferred precursor. The precursors can subsequently be used to make vanadium based electroactive materials and use of such precursor materials offers significant advantages over other processes known for preparing vanadium phosphate compounds.
