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.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The team’s battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.
