Recovery of strategic metals (cobalt, nickel) from lithium-ion batteries through adsorption and desorption: Insights in desorption mechanisms and ultrasound enhancement

The purification of wastewater and the recovery of strategic metals from spent batteries, such as Co2+ and Ni2+ were carried out using a sorption–desorption process with a chemically activated mesoporous carbon. The mesoporous carbon was chemically activated in mild conditions with NaClO2 and H2O2,...
