Abstract
AbstractSluggish kinetics and poor electrochemical stability limit the implications of Li‐rich layered oxide cathode materials, which are regarded as one of the most promising potential cathode materials for lithium‐ion batteries. In this work, a Na‐doped Li‐rich layered oxide (abbreviated as N‐LLO) cathode material is prepared through co‐precipitation combined with calcination. During the annealing process, partial Li2CO3 is substituted by Na2CO3, which helps to optimize the primary particles and realize Na doping. The obtained N‐LLO cathode exhibits a greater specific capacity and excellent rate performance. The characterization and DFT calculations suggest that the doped Na ions could reduce the formation of Li/Ni disorder defects, change local bond length, and enlarge Li interslab spacing conducive to Li‐ion diffusion, improving the rate performance.
