Abstract: A method for making a lithium battery cathode material is disclosed. A mixed solution including a solvent, an iron salt material, and a phosphate material is provided. An alkaline solution is added into the mixed solution until the mixed solution has a pH value ranging from about 1.5 to 5. The iron salt react with the phosphate material to form a plurality of iron phosphate precursor particles which are added in a mixture of a lithium source solution and a reducing agent to form a lithium iron phosphate precursor slurry. The lithium iron phosphate precursor slurry is heat-treated.

Abstract: The present disclosure relates to an electrode slurry of a lithium battery and an electrode formed from the electrode slurry. The electrode slurry includes an active component, a conductive agent, a binder, an organic solvent, and octylphenolpoly(ethyleneglycolether)x, wherein x=9-10. The active component, conductive agent, binder, organic solvent, and octylphenolpoly(ethyleneglycolether)x are mixed together.

Abstract: A lithium battery cathode composite material includes a number of composite particles. Each of the composite particles includes one lithium vanadium phosphate particle and a lithium iron phosphate layer. The lithium iron phosphate layer is disposed on a surface of the lithium vanadium phosphate particle. The lithium iron phosphate layer includes a number of uniformly disposed lithium iron phosphate particles.

Abstract: A method for making a lithium battery cathode material is disclosed. A mixed solution including a solvent, an iron salt material, a vanadium source material and a phosphate material is provided. An alkaline solution is added in the mixed solution to make the mixed solution have a pH value ranging from about 1.5 to 5. The iron salt, the vanadium source material and the phosphate material react with each other to form a plurality particles of iron phosphate precursor doped with vanadium which are added in a mixture of a lithium source solution and a reducing agent to form a slurry of lithium iron phosphate precursor doped with vanadium. The slurry of lithium iron phosphate precursor doped with vanadium is heat-treated.

Abstract: A method for making a lithium battery cathode composite is provided. First, a plurality of lithium vanadium phosphate particles is provided. A lithium iron phosphate layer is then formed on an outer surface of each of the lithium vanadium phosphate particle by coating a lithium iron phosphate precursor slurry, thereby forming the lithium battery cathode composite.
