Synchronous separation of Al foil and leaching of metals in cathode materials from spent lithium-ion batteries by a deep eutectic solvent

Key Points

• Metal leaching from spent lithium-ion batteries occurs effectively when using a deep eutectic solvent, enhancing metal recovery.
• Leaching yields indicate over 90% recovery of lithium and cobalt from the cathode materials within specific timeframes.
• Analysis involving spent batteries assesses the dual process of aluminum foil separation and metal leaching simultaneously.
• These findings highlight potential improvements in recycling techniques, indicating broader implications for sustainability in battery disposal.
