Direct regeneration of spent LiFePO a graphite prelithiation strategy
The capacity degradation mechanism of a spent LiFePO 4 (LFP) cathode was investigated systematically and the occurrence of FePO 4 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 regenera...

Summary: | The capacity degradation mechanism of a spent LiFePO
4
(LFP) cathode was investigated systematically and the occurrence of FePO
4
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.
A new, low-cost and green regeneration method was developed to revive spent LiFePO
4
-based batteries. |
