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.

摘要:
The invention provides an electrochemical cell having a first electrode having an electrode active material containing at least one electrode active material charge-carrier, a second electrode, and an electrolyte containing at least one electrolyte charge-carrier. In the electrochemical cell's nascent state, the at least one electrolyte charge carrier differs from the at least one electrode active material charge-carrier.
