Researchers designs new deep eutectic solvent to recover valuable elements from spent LNCM batteries

Green Car Congress

A team from Central South University in China has developed a new type of deep eutectic solvent (DES) that can efficiently leach metal elements from spent Ni-Co-Mn lithium-ion batteries (LNCM). The leaching rates of Ni, Co, Mn, and Li can all reach 99% under the conditions of T=140°C, t=10 min and no reductant.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. Haesun Park, Chung-Ang University, co-corresponding author.
