Freeze-Thaw Molten Source Battery for Energy Storage

Here’s an article from the Physics World website about a new approach to energy storage which is one of the biggest challenge facing the effort to move the electric grid to be powered by mostly renewable sources of electricity:

A battery that “freezes” its stored chemical energy for several months has been developed by Minyuan Li and colleagues at Pacific Northwest National Laboratory in the US. Their battery uses a molten salt electrolyte, which remains solid at room temperatures, and thaws out when heated.
