Lithium Leaching–Induced Activation of Spent LFP Composites for Enhanced Water Oxidation with Concurrent Lithium Recovery
Key Points
This research aims to enhance water oxidation processes by activating spent lithium iron phosphate composites through lithium leaching.
Developed a catalyst using spent lithium iron phosphate composites (s LFP@NiO) for oxygen evolution reaction.
Investigated the effects of lithium leaching on the catalytic performance.
Analyzed water oxidation efficiency and lithium recovery mechanisms.
Lithium leaching significantly enhanced the oxygen evolution reaction activity.
The modified catalyst showed improved performance over untreated composites.
Concurrent lithium recovery was successfully achieved during the process.
Abstract
We present a strategy for repurposing spent lithium iron phosphate cathodes into an efficient oxygen evolution reaction (OER) catalyst (s LFP@NiO). A key finding is that lithium leaching under OER...
