Abstract
An apparatus comprises a reaction chamber and at least one negative electrode reservoir configured to contain a negative electrode material. A heating system is configured to heat negative electrode material within the at least one negative electrode material reservoir and the reaction chamber and to heat positive electrode material in reaction chamber. An electrode material distribution system is configured to manage the transfer of fluid electrode material between the at least one negative electrode reservoir and the reaction chamber.
