One technology that has been under investigation since the 1980s uses a metal-based cathode (positive electrode) and a molten sodium anode (negative electrode) enclosed within a steel case. A ceramic isolator allows ions to pass between the electrodes, but not electrons, with travel through an external circuit during charging and discharging.
