Abstract:
Ultrahigh-nickel cathodes show promise but face challenges like surface microcracks, structural dislocations, and oxygen release, leading to performance loss. This work proposes Sr and Co co-doping in the single-crystal structure to enhance its stability and electrochemical performance, offering insights for designing durable, high-performance lithium-ion battery materials.
