At modest current densities, round-trip energy efficiencies of 99% can be achieved. Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Existing energy storage technologies cannot satisfy these requirements.

Nowadays, due to their outstanding energy and power density, Li-ion batteries have become a mainstay for EES [electrical energy storage]. However, the concerns regarding the high cost and the limited lithium reserves in the earth’s crust have driven the researchers to search more sustainable alternative energy storage solutions.

Sodium-ion batteries (Na-ion, NIBs) are seen as an alternative to lithium-ion batteries for large-scale applications due to their lower cost and abundant supply of sodium. However, low capacity and poor rate capability of existing anodes have been major obstacles to the commercialization of NIBs. —Yu et al.

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.
