  • Method for Making Lithium Transition Metal Olivines Using Water/Cosolvent Mixtures
    Publication number: 20150372303
    Abstract: Olivine lithium manganese iron phosphate is made in a coprecipitation process from a water/alcoholic cosolvent mixture. The LMFP particles so obtained exhibit surprisingly high electronic conductivities, which in turn leads to other advantages such as high energy and power densities and excellent cycling performance.

  • CO-SOLVENT ASSISTED MICROWAVE-SOLVOTHERMAL PROCESS FOR MAKING OLIVINE LITHIUM TRANSITION METAL PHOSPHATE ELECTRODE MATERIALS
    Publication number: 20150303473
    Abstract: Olivine lithium transition metal phosphate cathode materials are made in a microwave-assisted process by combining precursors in a mixture of water and an alcoholic cosolvent, then exposing the precursors to microwave radiation 5 to heat them under superatmospheric pressure. This process allows rapid synthesis of the cathode materials, and produces cathode materials that have high specific capacities.
