Abstract

LiNi1/3Co1/3Mn1/3O2 (NCM) with a one-dimensional (1-D) porous structure has been developed as a cathode material for Li-ion batteries. The tube-like 1-D structure consists of interlinked, multi-facet nanoparticles approximately 100-500 nm in diameter. The microscopically porous structure originates from the honeycomb-shaped precursor foaming gel, which serves as a self-template during the stepwise calcination process. The as-prepared NCM presents excellent discharge specific capacities as well as high electrochemical activity and cyclic stability, as proven by the cyclic voltammogram and electrochemical impedance spectroscopy.
