Researchers develop energy-efficient process to recycle Li-ion battery cathodes

Green Car Congress

Engineers at the University of California San Diego and the University of California Los Angeles have developed an energy-efficient approach to regenerate Li-ion battery cathode materials (using LiCoO 2 as a model material) by hydrothermal treatment of cycled electrode particles followed by short annealing.

Argonne team develops new approach to cobalt-free Li-ion cathodes

Green Car Congress

Researchers at Argonne National Laboratory have developed a new approach to cobalt-free Li-ion cathodes that avoids some of the problems with other low-cobalt cathode approaches. To make use of the best out of each of these three ions, the industry is now based on LiNi 1-y-z Mn y Co z O 2 with (1-y-z) 0.2). Croy, Brandon R.

UCSD researchers improve method to recycle and renew used cathodes from Li-ion batteries via eutectic molten salts

Green Car Congress

Researchers at the University of California San Diego have improved their recycling process that regenerates degraded cathodes from spent lithium-ion batteries. Zheng Chen, a professor of nanoengineering who is affiliated with the Sustainable Power and Energy Center at UC San Diego, led the project.
