US researchers say they have developed a way to make cobalt-free lithium-ion battery cathodes, while Ford says it has broken ground on a new $5.6 billion production complex for electric vehicles and batteries.University of California researchers and academics from four US national laboratories have devised a way to make lithium-ion battery cathodes without using cobalt - a metal that is rare, costly, and linked to unethical mining practices. In a recent paper in Nature, the scientists describe how they overcame thermal and chemical-mechanical instabilities of cathodes composed substantially of ...Den vollständigen Artikel lesen ...
