A Method of Efficiently Regenerating Waste LiFePO Cathode Material after Air Firing Treatment.

Waste LiFePO (LFP) batteries can be harmful to the environment and lead to waste of resources if not properly disposed of. In this study, an efficient and environmentally friendly method for solid-phase recycling waste LFP cathode material (W-LFP) is proposed. Most of the impurities in the W-LFP are removed by air firing.
