Abstract
Systems and methods for thermal gradient during electrode pyrolysis may include fabricating the battery electrode by pyrolyzing an active material on a metal current collector, wherein the active material comprises silicon particles in a binder material, the binder material being pyrolyzed such that a resistance at an inner surface of the active material in contact with the current collector is at least 50% higher than a resistance at an outer surface of the active material. The active material may be pyrolyzed by electromagnetic radiation, which may be provided by one or more lasers, which may include one or more COlasers. The electromagnetic radiation may be provided by one or more infrared lamps. An outer edge of the current collector may be gripped using a thermal transfer block that removes heat from the current collector during pyrolysis of the active material and subsequent cool down.
