Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

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. Weller et al.

Report: Sumitomo and Kyoto University developing lower temperature molten-salt battery; about 10% the cost of Li-ion

Green Car Congress

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.
