MoO nanosheets embedded in the amorphous carbon matrix (MoO/C) are successfully synthesized via a facile hydrothermal method and investigated as an anode for sodium-ion batteries. Because of the efficient ion transport channels and good volume change accommodation, MoO/C delivers a discharge/charge capacity of 367.8/367.0 mAh g with high coulombic efficiency (99.4%) after 100 cycles at a current density of 50 mA g.
通过一种简便的水热法成功合成了嵌入非晶碳基质中的MoO纳米片(MoO/C),并将其作为钠离子电池的负极进行了研究。由于具有高效的离子传输通道和良好的体积变化适应性,MoO/C在50 mA g的电流密度下循环100次后,放电/充电容量为367.8/367.0 mAh g,库仑效率高达99.4%。
