Transition metal oxides/sulfides/selenides (TMOSS), regarded as three of the most potential anode materials for lithium-ion batteries (LIBs), are superior to their low cost, controllable morphology and high theoretical capacity. Herein, a facile strategy, using Ni-MOF material as precursor, was designed to fabricate the unique micro-flowerfig-like NiO, NiS/C and NiSe/C electrodes, including the detailed investigation about their electrochemical and kinetics properties. The results show that sizes of NiO, NiS/C and NiSe/C micro-flowers are around 0.7, 3.5 and 2.0 μm, respectively, which contains abundant micro- and meso-pores. Among them, NiSe/C material exhibits better electrochemical performance when used as anode for LIBs，with high initial capacity (1688.4 mAh g⁻¹ at 0.1 A g⁻¹) and high reversible capacity (1016.5 mAh g⁻¹ at 1.0 A g⁻¹ after 1000 cycles). Moreover, the full-cell, NiSe/C vs. LiCoO₂, exhibits superior reversible discharge capacities of 421.8 mAh g⁻¹ at 0.1 A g⁻¹ after 50 cycles. It is important that the bond energy of Ni–Se contributes to improving NiSe/C electrochemical performance. This work shows the influence of Li⁺ insertion and pseudocapacitance behavior on lithium storage performance of TMOSS anode materials, which provides an effective strategy for research and development of TMOSS on LIBs.

过渡金属氧化物/硫化物/硒化物（TMOSS）被认为是锂离子电池（LIB）最具潜力的三种阳极材料，其价格低廉，形态可控且理论容量高。本文中，设计了一种以Ni-MOF材料为前体的简便策略，以制造独特的微花状NiO，NiS / C和NiSe / C电极，包括对其电化学和动力学性质的详细研究。结果表明，NiO，NiS / C和NiSe / C微花的大小分别约为0.7、3.5和2.0μm，其中包含大量的微孔和中孔。其中，NISE / C材料显示出更好的电化学性能时用作阳极LIBS，具有高初始容量（1688.4毫安克^-1在0.1 A克^-1）和高可逆容量（1000个循环后，在1.0 A g ^-1下为1016.5 mAh g ^-1）。此外，全电池NiSe / C与。LiCoO ₂在50个循环后，在0.1 A g ^-1下表现出421.8 mAh g ^-1的优异可逆放电容量。Ni-Se的键能有助于改善NiSe / C的电化学性能，这一点很重要。这项工作表明了Li ^+的插入和伪电容行为对TMOSS负极材料锂存储性能的影响，这为研究和开发TMOSS在LIB上提供了有效的策略。
