摘要： The ions other than lithium ions and having a greater ion radius are interposed, before the lithium ions are doped, as an interlayer securing member in a vanadium oxide having a layered crystal into which the lithium ions can be doped. Since the interlayer securing member is interposed, the doping or dedoping of the lithium ions into or from the vanadium oxide afterward can be smoothly performed. Sodium ions or the like can be employed as the interlayer securing member.

摘要： A process for producing a cathode powder for making lithium ion batteries wherein the powder comprises lithium, vanadium and a polyanion. The process includes forming a solution-suspension of the precursors, including vanadium pentoxide, with a reducing agent, a solvent, and a carbon-residue-forming material. The reducing agent reduces the vanadium in vanadium pentoxide from V5+ to V3+. The solution-suspension is heated in inert environment to drive synthesis of the LVP so the carbon-residue-forming material is oxidized and precipitates, forming CCLVP. Liquids are separated from solids and the dry powder is heated to drive crystallization of the product. The product retains small particle size, includes carbon in the LVP for conductivity, and is created with low cost precursors and with no need to reduce the product size for use in batteries. Addition of carbon black, graphite or other form of carbon is unnecessary to provide the conductivity required for use in batteries.
