A Room‐Temperature Lithium‐Restocking Strategy for the Direct Reuse of Degraded LiFePO 4 Electrodes

even after being exposed to air for 3 months. The DER strategy presents significant economic and environmental benefits compared with the DMR method. This research provides a timely and innovative solution for recycling spent blade batteries using large-sized LFP electrodes, boosting the closed-loop development of LFP batteries.
