Stanford University announces their development of a battery made of "Earth-abundant materials," capable of storing large amounts of electricity in a very cost-effective way. This may be the first flow battery to open the option of storing large amounts of solar power so that it can be distributed based on demand.

Stanford assistant professor of materials science and engineering William Chueh, along with his PhD student Antonio Baclig and Jason Rugolo, now a technology prospector at Alphabet’s research subsidiary X Development, decided to try sodium and potassium, which when mixed form a liquid metal at room temperature, as the fluid for the electron donor – or negative – side of the battery. Theoretically, this liquid metal has at least 10 times the available energy per gram as other candidates for the negative-side fluid of a flow battery.

“We still have a lot of work to do,” said Baclig, “but this is a new type of flow battery that could affordably enable much higher use of solar and wind power using Earth-abundant materials.”
