Liquid Metal Battery — a promising battery startup backed by Bill Gates, Khosla Ventures and oil giant Total — has changed it’s name to Ambri, a shorter and less literal word that’s a nod to Cambridge, where the company was founded.

Ambri battery

A promising battery startup backed by Bill Gates, Liquid Metal Battery, has changed its name to. . . Ambri.  The company, which is the brainchild of MIT Professor Don Sadoway, says the new name is a nod to Cambridge, which is where the company was founded. Ambri CEO Phil Giudice tells me that the new name is shorter, easier to say, less literal, and less confusing.

Ambri is developing a battery for the power grid using molten salt sandwiched between two layers of liquid metal. The battery is still about two years from commercialization, and the team has built a 16-inch prototype, though they might scale that up to 36 inches. The team is still figuring out if they want the battery to be squarish or circular.

Sadoway had the idea to create a battery that used super low cost materials and he believed a battery based on liquid metal electrodes would 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.

Sadoway met Bill Gates after the Microsoft-co-founder took an online class of his at MIT. Gates invested in the company, as did  oil company Total, and venture capital firm Khosla Ventures; the Department of Energy’s high risk early stage ARPA-E program also gave Ambri a $6.9 million grant.

    Hello Katie its very interest :-)

    Saw his appearance on ColbertShow- cannot wait to invest in such a tremendous innovation!

  5. why involve oil companies?

  6. the oil companies and governments will fight to stop it

    Maybe smart oil companies will ‘see the sriting on the wal”, the need to diversify and get in on the action in order to survive…. in the inevitable New World Order?!

  8. The oil companies already diversify. They bought the Ovonics NiMH battery company and sued Panasonic to shut down production.

  9. bout time! can’t wait to get me one…

  10. Given the scales-small size of the battery, this seems like it would be a good fit for local grids and home grids too (with proper insulation against the heat).
