Apr 2, 2026 - China`s retired EV batteries now light villages, store solar power and charge new cars
Children in remote mountain village in China can now read at night under streetlights that run on "second-life" EV batteries. As the world`s largest EV market, China is entering a "large-scale retirement phase" that is expected to peak in 2026. While a car battery is legally "retired" when its capacity drops to 70 or 80 percent, that still leaves a massive amount of energy, often 80 kilowatt-hours per pack. It means one retired car battery still powerful enough to run a home for days. Beyond streetlights, the real scale is found in massive energy storage stations. Hundreds of retired packs are stacked into giant "power banks" that store solar energy for the grid and charge new EVs. Starting in April 2026, China is tightening controls by mandating "Digital IDs" for every battery to track it from its first mile on the road to its final days. Today, the recycling rate for nickel, cobalt, and manganese can reach as high as 99.6 percent, and lithium 96 percent.
