  • Patent number: 10431820
    Abstract: The surface of a lithium ion cathode material (e.g., a lithium metal oxide material capable of releasing and accepting lithium ions during charging and discharging, respectively, of a lithium ion electrochemical cell) is coated with a lithium metal oxide (LMO) material comprising a high-valent metal to, inter alia, reduce interfacial resistance toward lithium exchange. Li-rich phases on the surface of the treated LMO particles allow for better lithium ion diffusion. The inclusion of elements that form phases with lithium and can substitute in the host structure allow for mixing across interfaces leading to more robust structures that better mimic epitaxial-type layers. Inclusion of doping elements in place of some of the high-valent metal in the surface-treating composition provides unexpectedly improved performance over surface treatments comprising lithium metal oxides that only include a high-valent metal.

  • Patent number: 10381678
    Abstract: A new battery cell structure uses a reduced stack pressure force to be used and applied over a much smaller area of the cells by using the sides of the cell instead of the top and bottom of the cell. To reduce the amount of force required to compress a cell, an edge-wise construction can be used instead of the sheet construction. Instead of stack pressure having to be applied to the top and bottom of the cell, it is now applied across the edges. An edge-on design is used to form strips, which allows for flat sides of a battery body.
