Direct repair of spent LiFePO4 via a closed-loop deep eutectic solvent process

Key Points

• Chemical recovery methods significantly enhance the recycling efficiency of lithium-ion batteries made with LiFePO4.
• Efficiency of the closed-loop process can potentially recover over 95% of valuable components from spent batteries.
• Analysis of the closed-loop deep eutectic solvent demonstrates its effectiveness in facilitating material recovery without harmful byproducts.
• This method underscores the importance of sustainable recycling initiatives for battery technologies in reducing environmental impact.
