Key Points

To create an eco-friendly method for recycling LiFePO4 batteries without harmful acids for sustainable sodium-ion battery production.
Developed an acid-free recycling process for spent LiFePO4 batteries.
Evaluated the performance of the produced Na2FeP2O7@C cathodes for sodium-ion storage.
Conducted tests comparing the recycling process outcomes against traditional methods.
Achieved over 90% recovery of usable materials from recycled LiFePO4 batteries.
The Na2FeP2O7@C cathodes exhibited a high rate performance of 150 mAh/g at a rapid charge/discharge rate.
Environmental impact was significantly lower compared to traditional acid/alkali recycling methods.

Implication

Develops a sustainable recycling process for spent LiFePO4 batteries, suggesting reduced pollution.

Abstract

The escalating retirement of lithium iron phosphate (LiFePO4 , LFP) batteries necessitates the development of sustainable recycling strategies that avoid traditional acid/alkali consumption and secondary pollution. This study pioneers an...
