source：newscenterLithium-ion batteries have revolutionized electronics and enabled an accelerating shift toward clean energy. These batteries have become an integral part of 21st century life, but we’re at risk of running out before 2050. The main elements used in each battery – lithium, nickel, and cobalt metals as well as graphite – are increasingly scarce and expensive, and there is little environmental or fair-labor oversight of some of the remaining international supply chains.There is a pressing need to start reusing the materials we’ve already dug up and to make the battery production p...
