DIRECT COATING OF ELECTRODES IN SILICON-DOMINANT ANODE CELLS

Systems and methods are provided for high volume roll-to-roll direct coating of electrodes for silicon-dominant anode cells and may include applying a slurry to a current collector film, the slurry comprising silicon particles and a binder material; drying the slurry to form a precursor composite film; rolling the current collector film into a precursor composite roll; and applying a heat treatment to the precursor composite film and the current collector film in a nitrogen gas environment, wherein the heat treatment is configured for converting the precursor composite film to a pyrolyzed composite film. The heat treatment may include one or both of: applying the heat treatment to a roll comprising the precursor composite roll in whole; and applying the heat treatment to the current collector film as it is continuously fed from the precursor composite roll.
