摘要
通过一步煅烧二维锌基配位聚合物[Zn(tfbdc)(4,4′-bpy)(H_2O)_2](H_2tfbdc=四氟对苯二甲酸;4,4′-bpy=4,4′-联吡啶),制备了氮掺杂碳/氧化锌复合纳米粒子(ZnO-N-C)。作为锂离子电池的负极材料,ZnO-N-C电极具有高的可逆容量,优异的循环稳定性和较好的倍率性能。在50 mA·g^(-1)的电流密度下,50次循环后ZnO-N-C电极仍有611 mAh·g^(-1)的可逆容量。
Nitrogen-doped carbon/ZnO nanoparticles (ZnO-N-C) have been synthesized via an ordinary one-step calcination of a two-dimensional zinc-based coordination polymer [Zn(tfbdc)(4,4′-bpy)(H2O)2](H2tfbdc=tetrafluoro-terephthalic acid, 4,4′-bpy=4,4′-bipyridine). As an anode material for lithium-ion batteries, the obtained ZnO-N-C electrode exhibited high reversible capacity, excellent cyclic stability and better rate capability. The reversible capacity of the ZnO-N-C electrode maintains 611 mAh·g^-1 after 50 cycles at a current density of 50 mA·g^-1.
