Sodium Batteries for the Grid

Caption

Sandia National Laboratories researchers Leo Small, back right, and Erik Spoerke, back left, observe as Martha Gross, front, works in an argon glove box on their lab-scale sodium iodide battery. This new kind of molten sodium battery could prove to be a lower-temperature, lower-cost battery for grid-scale energy storage.
