  • LMFP cathode materials with improved electrochemical performance
    Patent number: 9793538
    Abstract: Particulate LMFP cathode materials having high manganese contents and small amounts of dopant metals are disclosed. These cathode materials are made by milling a mixture of precursor materials in a wet or dry milling process. Preferably, off-stoichiometric amounts of starting materials are used to make the cathode materials. Unlike other high manganese LMFP materials, these cathode materials provide high specific capacities, very good cycle life and high energies even at high discharge rates.

  • Electrolyte Formulations For Electrochemical Cells Containing A Silicon Electrode
    Publication number: 20160240889
    Abstract: Additives to electrolytes that enable the formation of comparatively more robust SEI films on silicon anodes. The SEI films in these embodiments are seen to be more robust in part because the batteries containing these materials have higher coulombic efficiency and longer cycle life than comparable batteries without such additives.

  • Battery electrolyte solutions containing phosphorus-sulfur compounds
    Patent number: 9147906
    Abstract: A battery electrolyte solution contains from 0.001 to 20% by weight of certain phosphorus-sulfur compounds. The phosphorus-sulfur compound performs effectively as a solid-electrolyte interphase (SEI) forming material. The phosphorus-sulfur compound has little adverse impact on the electrical properties of the battery, and in some cases actually improves battery performance. Batteries containing the electrolyte solution form robust and stable SEIs even when charged at high rates during initial formation cycles.
