摘要

The hollow nanostructured Li(Ni1/3Co1/3Mn1/3)O2 (NCM) microspheres with low Li/Ni disorder werefabricated by precursor-template approach and investigated electrochemically as lithium ion batteries(LIBs) cathode. The as-obtained NCM microspheres cathode exhibits high specific capacity, goodcoulombic efficiency and outstanding rate capability. This might mainly be due to the unique hollownanostructured architectures of the NCM microspheres enabling to shorten Li+ diffusion and electrontransportation paths in the materials, which is verified via the cyclic voltammetry (CV) at various scanrate to obtain the high apparent Li+ diffusion coefficient for the discharge/charge processes.
