A new concept for batteries made from inexpensive, abundant …

The commercially dominant metal, iron, doesn''t have the right electrochemical properties for an efficient battery, he says. But the second-most-abundant metal in the marketplace—and actually the most abundant metal on Earth—is aluminum. "So, I said, well, let''s just make that a bookend. It''s gonna be aluminum," he says.
