  • Patent number: 12166203
    Abstract: A process for the formation of a deformable battery electrode includes mixing a metal component including at least one of a metal or a metal alloy, a polymer component, and a dispersant component to create a mixture. The method further includes heated the mixture to a temperature above the melting point of the metal or the metal alloy and agitating the mixture to form a dispersion of the (molten) metal or the metal alloy in the mixture. The method further includes cooling the mixture to a temperature below the melting point of the metal or the metal alloy to form a stabilized dispersion of the metal or the metal alloy. The polymer component includes a polymer having a melting point equal to or below that of the metal or the metal alloy and a glass transition temperature sufficiently low that the stabilized dispersion is deformable.

  • Publication number: 20230395847
    Abstract: Electrodes are disclosed that include a polymer electron donor, an electron acceptor, a lithium salt, and a solvent. In select embodiments, the components of the electrode may form a charge-transfer complex polymer (CTCP) to achieve high local lithium concentration and endow fast lithium mobility. In another aspect, an improved polymer electrolyte that uses block copolymers composed of monomers is described in which one of the monomers contains electron-rich pi systems and the other of the monomers contains electron-poor pi systems. The block copolymers may be combined with a salt to form the polymer electrolyte.
