Recycling and reusing worn cathodes to make new lithium ion batteries

Recycling and reusing worn cathodes to make new lithium ion batteries

Feb 6, 2018 United States
Nanoengineers at the University of California San Diego have developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries and makes them work just as good as new. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. Researchers built new batteries using the regenerated cathodes. Charge storage capacity, charging time and battery…
