  • Patent number: 10756321
    Abstract: The present invention relates generally to electrochemical energy storage devices such as Li-ion batteries, and more particularly to a method of providing uniform ceramic coatings with controlled thicknesses for separators in such storage devices. Some embodiments of the invention utilize a layer by layer coating of nano/micro-sized particles dispersed in a solvent, which can be aqueous or non-aqueous. Other embodiments of the invention utilize a dry process such as PVD for depositing a ceramic film on a porous polyolefin separator. According to certain aspects of the invention, advantages of this approach include the ability to achieve a denser more uniform film with better controlled thickness with less waste and higher yield than current ceramic coating technology. An advantage of a ceramic coated separator is increased safety of cells.

  • Patent number: 10170797
    Abstract: A lithium ion battery has a flat wound electrode assembly, a nonaqueous electrolyte, and a battery case. The nonaqueous electrolyte contains an electrically insulating inorganic aggregate and is formed of an impregnating electrolyte impregnated into the flat wound electrode assembly and a surplus electrolyte not impregnated into the flat wound electrode assembly. Letting the flat wound electrode assembly be divided into a planar region where the electrode surfaces are planar surfaces and a lower wound curved region which is positioned vertically downward from the planar region and where the electrode surfaces are curved, a boundary plane that includes the boundary between the planar region and the lower wound curved region, the inorganic aggregate amount MO included in a space which is below the boundary plane and the inorganic aggregate amount MI included in the impregnating electrolyte within the flat wound electrode assembly satisfy the relationship MO>MI.
