  • Methods for alkaliating roll anodes
    Patent number: 12646703
    Abstract: The present invention relates to processes that may be used singly or in combination to prevent lithium (or alkali metal) plating or dendrite buildup on bare substrate areas or edges of electrode rolls during alkaliation of a battery or electrochemical cell anode composed of a conductive substrate and coatings, in which the electrode rolls may be coated on one or both sides and may have exposed substrate on edges, or on continuous or discontinuous portions of either or both substrate surfaces.

  • Method for Alkaliating Electrodes
    Publication number: 20250300166
    Abstract: The present invention relates to a method for lithiation of an intercalation-based anode or a non-reactive plating-capable foil or a reactive alloy capable anode, whereby utilization of said lithiated intercalation-based anode or a plating-capable foil or reactive alloy capable anode in a rechargeable battery or electrochemical cell results in an increased amount of lithium available for cycling, and an improved reversible capacity during charge and discharge.

  • PRE-LITHIATED SILICON ANODES WITH PVDF BINDER
    Publication number: 20200259164
    Abstract: A pre-lithiated silicon anode comprising a PVDF binder at 5-12 wt. % for use in a Li-ion cell is provided. In particular instances, a conductive additive may be added at less than 5 wt. %. The Si anode with PVDF binder is pre-lithiated prior to cell assembly and following Si anode fabrication. The combination of pre-lithiation and PVDF in the Si anode for use in a rechargeable Li-ion cell shows the unexpected result of extending the cycle life.
