In a surprising twist, researchers have built a lithium-ion battery using a rust-based (iron) anode that increases its energy capacity over time. Instead of degrading with use, the battery reaches full performance after around 100 charge cycles. As the battery operates, metallic iron gradually converts into iron oxide, increasing the anode’s ability to store lithium ions. This self-improving behavior challenges the traditional assumption that batteries must lose capacity as they age. The approac
