Abstract
Systems and methods are provided for control of furnace atmosphere for improving capacity retention of silicon-dominant anode cells. Furnace atmosphere may be controlled during processing of a silicon-dominated electrode in a furnace, with the processing including pyrolysis of the silicon-dominated electrode, and the controlling including setting or adjusting one or more of pressure of the furnace atmosphere, and composition of the furnace atmosphere. The controlling of the furnace atmosphere may be configured based on at least one environment condition. The at least one environment condition may be an oxygen-free environment.
