Abstract: Systems and methods are provided for high volume roll-to-roll direct coating of electrodes for silicon-dominant anode cells. A slurry that includes silicon particles and a binder material may be applied to a current collector film, and the slurry may be processed to form a precursor composite film coated on the current collector film. The current collector film with the coated precursor composite film may be rolled into a precursor composite roll. A heat treatment may be applied to the current collector film with the coated precursor composite film in an environment including nitrogen gas, to convert the coated precursor composite film to a pyrolyzed composite film coated on the current collector film. The heat treatment may include applying the heat treatment to the precursor composite roll in whole and/or applying the heat treatment to the current collector film with the coated precursor composite film as it is continuously fed.

Abstract: A clamping device for a multilayered battery comprising one or more electrochemical cells is provided. The clamping device can include one or more plates, guided elastic members, and/or one or more layers of an interfacial material, such as foam pads or papers, to provide distributed pressure across one or more surfaces of the multilayered battery during cell formation and/or cycling. A compression plate is employed to provide a compressive force to compress the elastic members to a predetermined length, at which the position of the elastic members can be fixed.

Abstract: 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.

Abstract: Systems and methods are provided for direct coating of electrodes using pyrolysis of flat sheets in silicon-dominant anode cells. A plurality of flat electrode sheets may be formed, and at least a portion of the plurality of flat electrode sheets may be arranged into one or more stacks of flat electrode sheets. Each stack of flat electrode sheets may be placed onto a flat pyrolysis boat, and heat treatment (e.g., pyrolysis) may be applied to each flat pyrolysis boat. Forming of the flat electrode sheets may include use of cutting, punching, and/or notching, such as doing so based on predetermined electrode shapes and/or dimensions. The forming and/or arranging of the flat electrode sheets may be based on one or more predetermined criteria or considerations, such as shrinkage or expansion during the heat treatment.
