U.N. experts and rights groups estimate over a million people, mainly Uyghurs and other Muslim minorities, have been detained in a vast system of camps in Xinjiang in recent years. For lithium, the figure is 25%, and for cobalt and nickel it's 35%. Lead acid batteries were once rarely recycled, but now nearly all are broken down for reuse in internal combustion engines. For instance, for an ingot of silicon that is shaped into logs and then sliced into wafers, those individual wafers should be identified as having come from a particular log or batch. The departments scientists are working on reducing EV charging times to less than 15 minutes for a car to go 300 miles (483 km) and also to help reduce the cost of battery packs, which would make EVs more affordable, Granholm said.
Lead acid battery packs are still affordable
