Abstract
Systems and methods for use of perforated anodes in silicon-dominant anode cells may include a cathode, an electrolyte, and an anode, where the cathode and anode each comprise an active material on a current collector. One or both of the current collector and active material may be perforated. For example, the current collector may be perforated and/or both the current collector and active material may be perforated. The battery may comprise a stack of anodes and cathodes. Each cathode of the stack may be perforated and/or each anode of the stack may be perforated. Each cathode of the stack may comprise two layers of active material on each side of the cathode where a first of the two layers of active material may be for prelithiation of anodes of the battery. A second of the two layers may be for lithium cycling of the battery.
