TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises milling a lithium source, an iron source, a titanium source and a phosphate source at a molar ratio of 1:1-x:x:1, respectively, in a suspending medium to form a mixture, and pyrolyzing the mixture. Preferred Composition: The electrode further comprises conductive filler. Preferred Components: (I) is preferably lithium-iron-titanium-phosphate compound of formula ((0.985)LiFePO4Li(0.015)Ti(0.015)(PO4)a), ((0.95)LiFePO4Li(0.005)Ti(0.005)(PO4)a) or ((0.9)LiFePO4Li(0.1)Ti(0.1)(PO4)a). (A) portion is present as nanometer size domains within the lithium iron phosphate, which is 90 mole% or greater of (I). The lithium source comprises lithium carbonate (preferred), lithium hydroxide, lithium nitrate, lithium sulfate, lithium acetate, lithium dihydrogen phosphate or lithium oxalate. The iron source comprises iron oxalate dihydrate (preferred), iron nitrate, iron sulfate, iron acetate, iron carbonate, iron oxide or iron phosphate. The phosphate source comprises ammonium dihydrogen phosphate (preferred), diammonium hydrogen phosphate, ammonium phosphate, lithium dihydrogen phosphate or phosphoric acid. The titanium source comprises titanium oxysulfate (preferred), titanium sulfate, titanium chloride or titanium oxide. The conductive filler comprises carbon nanotubes, fullerenes, carbon black, graphite or graphene. The current collector comprises carbon paper, aluminum, nickel, platinum, palladium, gold, silver, copper, iron, stainless steel, rhodium, manganese, vanadium, titanium or tungsten.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The binder comprises poly(acrylonitrile), poly(vinylidene fluoride), polyvinyl alcohol, polyethylene, polystyrene, polyethylene oxide, polytetrafluoroethylene, polyimide, styrene butadiene rubber, carboxy methyl cellulose, gelatin, and/or their copolymers or blends. EXAMPLE - Lithium carbonate (2.3 g), ferrous oxalate dihydrate (10.3 g), titanium(IV) oxysulfate (1 g) and ammonium phosphate (7.3 g) were mixed and milled with zirconia balls and a small amount of acetone. The resulting well-mixed paste was allowed to dry to form a powder, and then packed into an alumina boat. The powder was then fired in a furnace with a surrounding argon atmosphere at 700 degrees C for 12 hours, and then pyrolyzing to give lithium-iron-titanium-phosphate compound of formula ((0.9)LiFePO4.Li(0.1)Ti(0.1)(PO4)a) (10 g).
