Closed-loop recovery of waste lithium iron phosphate by safe and environmentally friendly nitric acid selective leaching with bipolar membrane
Key Points
The aim is to develop a closed-loop recycling process for lithium iron phosphate using safe reagents.
Utilized HNO3/H2O2 for selective leaching of lithium iron phosphate.
Employed bipolar membrane electrodialysis for lithium recovery.
Converted nitric acid into a non-hazardous reagent.
Effectively recovered lithium iron phosphate from battery waste.
Minimized environmental hazards through the closed-loop process.
Abstract
Closed-loop process with HNO 3 /H 2 O 2 selective leaching and bipolar membrane electrodialysis (BMED) for hazard-free LiFePO 4 battery recycling, converting HNO 3 to safe reagent.
