Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. The team previously reported a neutral molten salt reaction.

in partnership with Kyoto University, has developed a lower temperature molten-salt rechargeable battery that promises to cost only about 10% as much as lithium ion batteries. Molten-salt batteries use highly conductive molten salts as an electrolyte, and can offer high energy and power densities.

Lithium-ion and molten-salt battery costs will approach $500/kWh by 2022, reducing the high capital cost of emerging grid storage technologies. Li-ion batteries are dependent on cost reductions from mass production while molten-salt batteries and VRFBs rely on long discharge durations to reduce costs.
