摘要：Uniform MoO2nanoparticles were synthesized and evaluated as intercalation-type lithium anode material within the potential window of 1.0–2.5 V. A remarkable high capacity of 226 mA h g−1at 0.1 C and ultra-long cycle life of 7000 cycles at 5 C with capacity retention of 135 mA h g−1(96% of initial capacity) have been achieved, which is comparable than that of commercial Li4Ti5O12anode but with higher capacity. Furthermore, a full cell composed of MoO2anode and LiCoO2cathode was assembled exhibiting a high energy density of 179 Wh kg−1(based on total mass of cathode and anode active material) and capacity retention of 169 mA h g−1(87% of initial capacity) after 500 cycles at 1 C.
