Abstract:
Zn and F elements are introduced into the lattice of Li-rich layered oxides, and the experimental results strongly prove that the dual-doping effectively alleviates surface-interface reactions and significantly improves surface structural stability. As a result, the dual-doped sample delivers an excellent capacity retention ratio as large as 86.9% after 200 cycles.
