Entropy-Engineered Fe–O–Ni Orbital Coupling Enables Durable Co-Free Ni-Rich Layered Cathodes

Abstract Cobalt-free Ni-rich layered cathodes are promising for high-energy-density lithium-ion batteries, but their practical implementation is hindered by coupled Li/Ni cation disorder, lattice oxygen instability, and interfacial degradation originating from the unstable Ni–O e...
