Cars That Think

APRIL 15, 2022

Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required.

Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. Nickel offers relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt. Nickel-rich cathode materials have real potential to store more energy.

The winning concepts were: A molten air battery that uses a molten salt electrolyte at elevated temperature from Professor Stuart Licht at George Washington University. Sustainable technologies should make it possible to store power from the grid and feed power back into it.

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.
