  • Patent number: 10854882
    Abstract: A method of forming an electrode includes attaching a tab to a collector to form a pre-tabbed current collector; disposing the pre-tabbed current collector onto a non-stick substrate to form a workpiece; and casting a slurry onto the workpiece to form a film. The slurry includes an active material component, one or more carbon additives, and at least one of a filamentary copper additive and a dendritic copper additive. The method includes drying the film at a first temperature to form a dried film; curing the dried film under pressure at a second higher temperature to form a cured film; removing the cured film from the non-stick substrate to form a precursor film; and carbonizing and annealing the precursor film at a third higher temperature. Carbonizing forms a three-dimensional electrically-conductive network and annealing forms a second contiguous network of copper connected to the active material component to form the electrode.
