Abstract

xLi2MnO3-(1-x)LiNi0.33Co0.33Mn0.33O2 (x=0.4, 0.5 and 0.6) lithium-rich layered cathode materials were synthesized using a bio-inspired method. Nanoporous radial structures composed of nanometric crystalline units, inherited from bio-mimetically synthesized MCO3 (MMn, Co, Ni) precursors, were obtained for the xLi2MnO3-(1-x)LiNi0.33Co0.33Mn0.33O2 particles. High discharge capacity of 263mAh/g and stable cycle performance were obtained from 0.4Li2MnO3-0.6LiNi0.33Co0.33Mn0.33O2 cathodes. Phase separation caused by the incomplete oxidation of metal ions was identified for the metal oxide intermediates topotactic transformed from the bio-mimetically synthesized MCO3 precursors, and caused the degradation of xLi2MnO3-(1-x)LiNi0.33Co0.33Mn0.33O2 with a high x ratio.
