Electrochemical bath restores dead lithium batteries to 95% capacity

Researchers have discovered a simple electrochemical bath that can revive depleted lithium batteries. The process involves immersing the cells in a specially formulated electrolyte solution. After treatment, the batteries regain up to 95% of their original charge capacity. The technique could extend the life of batteries used in electric vehicles and consumer electronics. It offers a cost‑effective alternative to recycling or replacing spent cells. The study demonstrates that chemical restoration can reverse degradation mechanisms. Industry experts see potential for scaling the method in large‑scale battery production. Further testing will determine the long‑term stability of the restored cells.
