Furthermore, the lithium insertion and extraction reactions that take place during charge and discharge, respectively, occur with no significant contraction/expansion of the crystal lattice, resulting in a much higher cycle life. 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.
