    Abstract: The present disclosure provides a battery pack component including a self-healing coating. The self-healing coating is disposed on at least a portion of a surface of the battery pack component. The self-healing coating includes a first precursor including a cyclic ether capable of reacting in a self-healing cationic ring-opening polymerization reaction. The self-healing coating further includes an initiator including an alkali metal salt. The self-healing cationic ring-opening polymerization reaction occurs when a defect is present in the self-healing coating. In certain aspects, the cyclic ether may include 1,3-dioxolane (C3H6O2) and the initiator may include lithium bis(fluorosulfonyl)imide (F2NaNO4S2). In other aspects, the self-healing coating may include a second precursor that is capable of copolymerizing with the first precursor. In still other aspects, the present disclosure provides a method of making a self-healing coating for a battery pack component.

  • Patent number: 10424776
    Abstract: Using the generally used coating method of an active material paste to a metal foil on a 3DF made the electrode properties instable due to residual air inside of the 3DF, and had the risk of causing micro short circuit of the battery due to metal fine powder and the like adhered to the 3DF and the 3DF exposed to the electrode surface. To solve the above-mentioned, the coating of the active material paste to the 3DF was made into a two-step coating process as shown below. Step one removes the air and fills the paste at the same time by applying the paste flow from one side of the 3DF (the first step coating process). Step two coats a new paste onto the surface of the electrode obtained by step one (the second step coating process).

  • Patent number: 10333148
    Abstract: Density modulated thin film electrodes, methods of making the same, and applications of the same. The density modulated thin film electrode includes a substrate formed of a current collecting material, and a thin film formed of an electrode material on the substrate. The thin film has a first surface and an opposite, second surface, and a density that is changed with a distance defined from the first surface to a plane in the thin film, the plane being parallel to the first surface. The method includes depositing the electrode material on the substrate to form the thin film, where, during deposition of the electrode material, a pressure of an operating gas is controlled and changed to a predetermined pressure value according to a deposited thickness of the electrode material, so as to make the density of the thin film changed with the distance.

  • Patent number: 10312499
    Abstract: Particles of active electrode material for a lithium secondary battery are coated with a precursor material which is either a carbon-based polymer or a metal and oxygen containing compound. The precursor material-coated particles are injected into a gas stream and momentarily exposed to an atmospheric plasma at a predetermined energy level and temperature up to about 3500° C. The plasma treatment converts (i) the carbon polymer to submicron size carbon particles or (ii) the metal compound to metal oxide particles on the surfaces of the particles of electrode material. In preferred embodiments of the invention the plasma treated coated active electrode material particles are carried by the gas stream and deposited onto an electrode material bearing substrate for a lithium battery cell.
