Abstract
The possibility of Mn-based Li-rich layered oxides 0.3Li2MnO3·0.7LiNi1/3Co1/3Mn1/3O2 as anode material for Li-ion batteries is explored. Ex-situ XRD patterns show that the layered structure remained when discharged to 1.2 V and the phase of Li2O and transition metal (Ni, Mn and Co) emerged when discharged to 0.05 V, indicating that there exists conversion reaction mechanism like transition-metal oxides anode material. The reversible capacities reach 574.2 and 449.8 mAh gâ1 at the current density of 50 mA gâ1 and 200 mA gâ1 respectively after 80 cycles. This study suggests that further optimizing Mn-based Li-rich layered oxides is a promising alternative anode material for Li-ion batteries.
