Orthophosphate electrodes for rechargeable batteries

Abstract

The orthophosphate electrodes for rechargeable batteries include an anode and a cathode, each formed from an orthophosphate material, for use in a conventional electrolytic cell-type rechargeable battery. The orthophosphate anode is an anode formed from an orthophosphate material having the formula A2T2B(PO4)3, and the orthophosphate cathode is a cathode formed from an orthophosphate material having the formula A3T2B(PO4)3, where A represents an alkali metal and T and B each represent a transition metal. The alkali metal may be lithium (Li) sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), monovalent cations thereof, or combinations thereof and each transition metal may be titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), or combinations thereof. The transition metal may be a divalent or trivalent transition metal
