摘要：A method of forming a polyanion active material that includes providing acarbon source, providing a mobile ion source, providing an active metal material,providing a network material, providing a flux material, and mixing the various materials.

In one aspect, the mixing step may include grinding or pulverizing materials to a uniformfine mixture. In one aspect, a ball mill may be utilized to mix the components. Followingthe mixing of the materials, the mixture is heated to a predetermined temperature in anon-oxidizing atmosphere to form a reaction product. In one aspect, the mixture isheated to a temperature above a melting temperature of the flux material. In thismanner, the flux material provides a medium in which the various reactants may react toform the desired reaction product. Following the heating of the mixture the reactionproduct is washed, forming a carbon coated polyanion active material. Also disclosed is apolyanion active material that includes the in situ reaction product of a carbon source,mobile ion source, active metal material, network material, and a flux material whereinthe polyanion active material includes a carbon coating formed thereon.
