The battery uses molten antimony and molten magnesium separated by an electrolyte. Sadoway claims that the all-liquid configuration is self-assembling and is expected to be scalable at low cost. Furthermore, this technology may have a shot at being cheaper than sodium sulfur (NaS) batteries. The team has since received $7 million from ARPA-E and $4 million from Total and has spun out a firm called the Liquid Metal Battery Company. And now Bill Gates has added his two cents. Sadoway's research ranges from metals production and portable energy storage devices to his "liquid battery," which has applications in grid-level storage for renewable energy applications -- to some extent inspired by aluminum smelters. Sadoway has spoken about how rechargeables have improved as we progressed from lead acid at 35 Wh/kg to Li-ion at 150 Wh/kg (versus gasoline at 12,000 Wh/kg). But Sadow...
