The capacity degradation mechanism of a spent LiFePO4 (LFP) cathode was investigated systematically and the occurrence of FePO4 in the cathode due to loss of Li+ was found to be mainly responsible for the short cycle life of LFP batteries. Given this, an easy, low-cost, and green cathode regeneration method was proposed. This work provides a new perspective for the recycling of spent batteries.
