Abstract
A battery with improved properties is provided. The battery has a cathode material prepared by the complexometric formulation methodology comprising MjXp wherein: Mj is at least one positive ion selected from the group consisting of alkali metals, alkaline earth metals and transition metals and n represents the moles of said positive ion per mole of said MjXp; and Xp is a negative anion or polyanion selected from Groups IIIA, IV A, VA, VIA and VIIA and may be one or more anion or polyanion and p representing the moles of said negative ion per moles of said MjXp. The battery has a discharge capacity at the 1000th discharge cycle of at least 120 mAh/g at room temperature at a discharge rate of 1 C when discharged from at least 4.6 volts to at least 2.0 volts.
