    Abstract: This invention relates to lithium-ion batteries and cathode powders for making lithium-ion batteries where the cathode powder comprises a blend or mixture of at least one lithium transition metal poly-anion and with one or more lithium transition-metal oxide powders. A number of different lithium transition-metal oxides are suitable, especially formulations that include nickel, manganese and cobalt. The preferred lithium transition metal poly-anion is carbon-containing lithium vanadium phosphate. Batteries using the mixture or blend of these powders have been found to have high specific capacity, especially based on volume, high cycle life, substantially improved safety issues as compared to lithium transition-metal oxides, per se, and an attractive electrode potential profile.

    Abstract: A non air-blown low sulfur heavy aromatic mineral oil which does not produce acceptable isotropic coke when subjected to delayed coking is combined with an inorganic additive which promotes pyrolysis and which vaporizes during calcining and the combination is subjected to delayed coking to produce isotropic coke having a low CTE ratio. The isotropic coke is further processed (including calcination) to produce graphite logs used in nuclear reactors.

    Abstract: This invention relates to a process for making carbon coated graphitic anode powders for use in batteries including rechargeable lithium-ion batteries wherein the process includes a side product isotropic pitch for use as a precursor in other products and more preferably, as a coating material for other powder or particle products. The process includes the steps of solvent extraction of volatile materials from high volatile material green coke powder. When a desirable amount of the volatile materials have been extracted, the solvent strength is altered to cause some of the volatile materials to precipitate on the powder particles to coat the same. The coated and solvent-extracted particles are then separated from the solvent and oxidatively stabilized, then carbonized and preferably graphitized. The volatile materials remaining in the solvent are valuable and are recovered for use in other processes and other products.

    Abstract: This invention relates to a process for producing an improved 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, which include vanadium pentoxide, with a reducing agent, a solvent, and a carbon-residue-forming material. The reducing agent causes the vanadium in vanadium pentoxide to reduce from V5+ to V3+. The solution-suspension is heated in an inert environment to drive the synthesis of the LVP (Li3V2(PO4)3) such that the carbon-residue-forming material is also oxidized to precipitate in and on the LVP forming carbon-containing LVP or CCLVP. The liquids are separated from the solids and the dry powder is heated to a second higher temperature to drive the crystallization of the product. The resulting product retains a small particle size, includes carbon in the LVP for conductivity and is created with very low cost precursors and avoids the need for milling or other processing to reduce the product to a particle size suitable for use in batteries. It also does not require the addition of carbon black, graphite or other form of carbon to provide the conductivity required for use in batteries.
