ReportEfficient Direct Recycling of Lithium-Ion Battery Cathodes by Targeted Healing
Context & Scale
The consumption of lithium-ion batteries is experiencing booming growth in the modern industry due to their widespread applications. With billions of batteries reaching their lifetime soon, significant concerns on the economic and environmental issues have been raised about how to treat these spent batteries so that our society will not face similar crisis incurred in the case of plastic wastes. However, traditional technologies used in today’s recycling industry are limited to recovering expensive metals through energy-intensive processes, which cause significant greenhouse gas emissions and secondary wastes, posing additional environmental concerns. To tackle this challenge, we developed a safe, low-cost, and efficient direct recycling approach that is based on targeted healing. This paradigm-shift method leverages our understanding on phase and structure evaluations of the LIB cathode and produces ready-to-use recycled cathode materials that match the electrochemical performance of pristine materials.
