The new cobalt-free battery yields about 60% greater energy density than conventional lithium-ion batteries for an equivalent weight and volume and sustains unprecedented 1,000 cycles.Today's electric vehicles are predominantly powered by nickel-manganese-cobalt (NMC) lithium-ion batteries. However, the inclusion of cobalt in this type of batteries has been considered as problematic due to its anticipated scarcity as well as associated supply chain risks related to its single source, human rights and mining practices. Now, a team led by researchers from the University of Tokyo has designed a ...Den vollständigen Artikel lesen ...
