Sadoway and MIT team demonstrate calcium-metal-based liquid metal battery

Green Car Congress

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.
