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

Abstract: The lithium-sulfur rechargeable battery (10) includes a negative electrode (14) formed from a composite of sulfurized polyacrylonitrile (SPAN), carbon black and carbon nanofibers coated on an aluminum substrate. The negative electrode (14), a corresponding positive electrode (16), an electrolyte (20) and a separator (18) are each disposed within a cell housing (12). The positive electrode (16) is formed from an alkali metal, an alkaline earth metal or salts thereof. The alkali metal of the positive electrode (16) may be, for example, lithium, sodium, potassium or cesium, and the alkaline earth metal of the positive electrode (16) may be, for example, magnesium, calcium or barium. Alternatively, the positive electrode (16) may be formed from aluminum, silver, zinc, hydrogen or salts thereof. The electrolyte (20) is formed from an alkali metal salt dissolved in an organic solvent.
