Battery Recycling

EV batteries get second lives through repair, reuse or recycling after removal

When an EV battery is taken out of a car — due to reduced range, a fault, or crash damage — technicians inspect and test it to decide its next stage of life rather than discarding it. Depending on its condition, individual modules may be repaired and the pack reused in another compatible vehicle, or the battery may be repurposed for stationary energy storage or sent for recycling. Severely damaged packs, such as those from total-loss crashes, are harder to salvage.

Cornell researchers restore aging lithium-ion battery electrodes without shredding them

Cornell University scientists created a process called Direct Electrode-to-Electrode Regeneration (DEER) that revives worn EV battery electrodes by chemically stripping excess solid electrolyte interphase buildup rather than shredding cells into raw materials. Treated electrodes recovered up to 95% of original capacity and degraded more slowly than untreated batteries, and a second treatment round restored capacity to 90% even after prior regeneration.
