摘要

超高镍阴极前景光明，但也面临着表面微裂纹、结构位错和氧气释放等挑战，从而导致性能下降。本研究提出在单晶结构中掺杂锶和钴，以提高其稳定性和电化学性能，为设计耐用、高性能的锂离子电池材料提供见解。

Sr and Co Co-doping Stabilizes Ultrahigh-Nickel Single-Crystal Cathodes for High-Performance Lithium-Ion Batteries

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.
