Power/Performance Bits: Feb. 6


Recycling cathodes Nanoengineers at the University of California San Diego developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. In new batteries built with the cathodes, charge storage capacity, charging time and ba... » read more
