      Liquid Metal Battery status

      In this formulation, MIT Prof. Sadoway explains, the battery delivers current as magnesium atoms lose two electrons, becoming magnesium ions that migrate through the electrolyte to the other electrode. There, they reacquire two electrons and revert to ordinary magnesium atoms, which form an alloy with the antimony. To recharge, the battery is connected to a source of electricity, which drives magnesium out of the alloy and across the electrolyte, where it then rejoins the negative .

      Stanford Researches Lithium-Sulfur Cathodes
      According to Yi Cui, a Stanford associate professor of materials science and engineering, putting silicon nanowire anodes and sulfur-coated carbon cathodes into one battery is the next generation of battery design. "Sulfur is one of the materials that can offer a 10-times higher charge storage capacity but with about half the voltage of the existing battery," Cui said.
