Removal of residual contaminants by minute-level washing facilitates the direct regeneration of spent cathodes from retired EV Li-ion batteries
Our study presents a minute-level water-based pretreatment that purifies degraded cathodes, enhancing lithium diffusivity and capacity retention in rejuvenated cathodes compared to contaminated ones.
