Though most efforts to make electric vehicle (EV) batteries without using heavy metals are still undergoing laboratory tests, a Chinese firm called SVOLT announced it is ready to start producing a cobalt-free battery at scale.
Tesla is working hard to improve its recycling methods in order to close the loop on EV battery recycling — earlier this month, the EV automaker announced it can now recycle 92 percent of battery cell materials. Firms such as Tesla, IBM, and Panasonic are also doubling down on efforts to make electric batteries without using heavy metals.
Lithium-ion batteries are made using heavy metals such as cobalt which are scarce and are also typically mined in areas known for human rights-related labor violations and environmentally destructive practices.
