Lithium Ion Cells Don’t Need Cobalt

A cobalt-free high-energy lithium-ion battery is possible, according to the University of Texas at Austin. The cathode is made from 89% nickel, then manganese and aluminium, part of a group of alloys dubbed NMAs. They were compared with high-nickel (both also 89%) cobalt-inclusive alloys from groups called nickel-manganese-cobalt (NMC) and nickel-cobalt-aluminium (NCA), described as “the
