Precursor-template Strategy toward Hollow Nanostructured Li(Ni1/3Co1/3Mn1/3)O2 Microspheres Cathode with Enhanced Electrochemical Performance

The hollow nanostructured Li(Ni 1/3 Co 1/3 Mn 1/3 )O 2 (NCM) microspheres with low Li/Ni disorder were fabricated by precursor-template approach and investigated electrochemically as lithium ion batteries (LIBs) cathode. The as-obtained NCM microspheres cathode exhibits high specific capacity, good coulombic efficiency and outstanding rate capability. This might mainly be due to the unique hollow nanostructured architectures of the NCM microspheres enabling to shorten Li + diffusion and electron transportation paths in the materials, which is verified via the cyclic voltammetry (CV) at various scan rate to obtain the high apparent Li + diffusion coefficient for the discharge/charge processes.
