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. A long road, in other words, lies ahead.

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.

It has been conducting research on batteries for over 30 years, including extensive work on advanced materials, particularly molten salts, lithium iron phosphate and nanotitanates. Hydro-Québec invests more than $100 million per year in research.

MIT professor Donald Sadoway and his team have demonstrated a long-cycle-life calcium-metal-based liquid-metal rechargeable battery for grid-scale energy storage, overcoming the problems that have precluded the use of the element: its high melting temperature, high reactivity and unfavorably high solubility in molten salts.
