The advancement of innovative Mo2C anode yet faces the challenge of exploring a simple, convenient and controllable synthetic route. β-Mo2C was prepared by utilizing low-cost hexamethylenetetramine and ammonium molybdate as raw materials and employing simple calcination treatment under N2 atmosphere. When applied as an anode for lithium ion batteries (LIBs), β-Mo2C delivers a satisfactory rate performance (147.0 and 103.4 mAh g−1 at 0.5 and 1.0 A g−1) and excellent cyclic stability (72.2 mAh g−1 at 2.0 A g−1 after 1500 cycles). Meanwhile, a suitable voltage plateau at ∼1.4 V for β-Mo2C also avoids the formation of lithium dendrites to improve the safety of LIBs.

具有适当嵌入电位的β-Mo2C作为锂离子电池负极材料的设计

创新Mo 2 C负极的进步仍面临探索简单、方便、可控合成路线的挑战。以低成本的六亚甲基四胺和钼酸铵为原料,在N 2气氛下进行简单的煅烧处理,制备出β-Mo 2 C。当用作锂离子电池(LIB)负极时,β-Mo 2 C具有令人满意的倍率性能(0.5和1.0 A g -1下分别为147.0和103.4 mAh g -1)和优异的循环稳定性(72.2 mAh g -1 ) 1500次循环后2.0 A g -1)。同时,β-Mo 2 C的合适电压平台在~1.4 V也可以避免锂枝晶的形成,从而提高LIB的安全性。
