Molten salt sandwiched between two layers of liquid metal constitutes the inside of a new battery developed by Ambri, a company founded in Cambridge, and the evolving creation of MIT Professor Don Sadoway. The company and the battery is now backed by Bill Gates, who met Sadoway after he took an online class of his at MIT.
This startup is developing the battery based on liquid metal electrodes to be stable and scalable at an acceptably low cost for grid storage and renewable energy storage applications.
“A dirt cheap battery that could be used for the power grid could overcome the variable nature of clean power or the problem that the sun only shines and the wind only blows at certain times of day.”
It should be ready for commercialization in about 2 years.
Along with Gates, oil company Total and venture capital firm Khosla Ventures have invested in Ambri, as well as the Department of Energy’s high-risk, early-stage ARPA-E program, which gave Ambri a $6.9 million grant.

Former Tesla Battery Expert Leading Lyten Into New Lithium-Sulfur Battery Era — Podcast:
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
