Forward-looking: Lithium-ion batteries are everywhere, but their cost, supply chain issues, and potential to fail in fiery ways make them less than ideal for grid-scale energy storage. Chinese researchers say they have taken a major step toward an alternative in the form of an all-iron flow battery built from cheap, abundant materials and a water-based electrolyte that cannot explode.
