Characteristics of the Carb Tek® Molten Salt Battery

A pilot line facility is in operation to evaluate the engineering and economic aspects of the Carb Tek^® molten salt cells and batteries. Presently, cells are meeting the design objective of 5 Wh/in³ (0.3 Wh/cc) of cathode, corresponding to about 28 Wh/lb (61.9 Wh/kg of cell. These cells and batteries are being designed for fork-lift truck applications. Design parameters for a 25 kW · h battery are: 720 A · h at a 6 h rate, producing in excess of 3000 Wh/ft³ (106,000 Wh/m³) at voltages of 30-36 V, and an energy density of about 30 Wh/lb (66.3 Wh/kg).
