  • 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.

  • Publication number: 20050250893
    Abstract: The present invention relates to a composite of an exfoliated clay pillared in a carbonized matrix. A substantially complete exfoliation of the clay can easily be achieved by first dispersing the in a viscous, high dielectric organic matrix to form a precursor composite, which can then be carbonized to form the composite of the exfoliated clay pillared in a carbonized matrix. The composite is useful as a filler, for example, to enhance the mechanical, thermal, and barrier properties of polymers.
