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 (M[dbnd]Mn, Co, Ni) precursors, were obtained for the xLi2MnO3-(1 − x)LiNi0.33Co0.33Mn0.33O2 particles. High discharge capacity of 263 mAh/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.
