摘要：
Systems and methods utilizing water soluble (aqueous) PAA-based polymer binders for silicon-dominant anodes may include an electrode coating layer on a current collector, where the electrode coating layer is formed from silicon and a pyrolyzed water soluble PAA-based polymer blend, wherein the water soluble PAA-based polymer blend comprises PAA and one or more additional water-soluble polymer components. The electrode coating layer may include more than 70% silicon and the anode may be in a lithium ion battery.
