Dual-doping structural design keeps cobalt-free, nickel-rich battery cathodes stable under high voltages, solving degradation problem

https://www.eurekalert.org/news-releases/1134336

"removes cobalt from battery supply chain without sacrificing high-voltage performance... iron (stabilizes local electronic oxygen environment)/ zirconium (provides lattice-anchoring) combination introduced into lithium nickel manganese oxide cathode... retains >81% capacity after 200 high-voltage cycles, while accelerating lithium-ion diffusion... suppresses structural breakdown/ dangerous oxygen loss during deep charging... lower-cost, safer, and high-performance electric vehicle batteries"
