Electrochemical-redox process expands recycling potential for LFP batteries

Summary
Lithium iron phosphate (LFP) batteries are attractive for stationary storage due to safety and longevity, but current recycling relies on expensive, hard-to-scale hydrometallurgy. NEU Battery Materials has introduced an electrochemical redox process that converts spent LFP into battery-grade lithium hydroxide or lithium carbonate with lower costs and carbon emissions, potentially broadening viable end-of-life pathways for LFP cells.

What do you see as the biggest hurdles to scaling electrochemical LFP recycling—feedstock collection, process throughput, regulatory approvals, or market demand for recovered LiOH/Li2CO3?

Lithium-iron-phosphate (LFP) batteries offer a compelling combination of performance characteristics for stationary energy storage, including improved safety and longevity, when compared to other lithium battery chemistries, such as nickel- and cobalt-based formulations. However, there are limited recycling pathways dedicated to end-of-life LFP batteries outside of high-cost hydrometallurgical processes that are challenging to scale with market demand. A new technology developed by NEU Battery Materials employs an electrochemical redox process to recycle LFP battery materials into battery-grade lithium hydroxide (LiOH) or lithium carbonate (Li2CO3) with much lower costs and carbon emissions than traditional recycling methods.
