采用二次水热法在泡沫镍上大规模生长了NiCo2S4纳米管阵列，并获得了良好的附着力。采用SEM、XRD和EDS对材料进行了表征。结果表明，NiCo2S4纳米管直接生长在泡沫镍上，平均内径约为55 nm，外径约为100 nm，长度约为102 μm。当作为LIB的无粘合剂阳极进行评估时，NiCo2S4纳米管阵列表现出出色的锂存储性能，包括高比容量，优异的循环稳定性和理想的倍率性能。在0.2 C倍率下，NiCo2S4纳米管阵列在50次循环中的平均放电容量为720 mAh g− 1，略高于其理论容量703 mAh g−1。当电流恢复到0.2 C时，NiCo2S4纳米管仍然可以稳定地提供652 mAh g−1的放电容量，达到初始0.2 C时的92.7%。循环伏安法（CV）测试表明，NiCo2S4纳米管阵列具有Ni和Co两种电化学反应行为，具有作为高性能锂离子电池负极材料的潜力。
A facile twice-hydrothermal method is developed for large-scale growth of NiCo2S4nanotube array on Ni foam with robust adhesion. As-prepared materials are characterized by SEM, XRD and EDS. It can be observed that NiCo2S4nanotubes directly grow on Ni foam with an average inner-diameter of ∼ 55 nm, external-diameter of 100 nm, and length of ∼ 2 μm. When evaluated as a binder-free anode for LIBs, NiCo2S4nanotube array exhibits outstanding lithium-storage performance that includes high special capacity, excellent cyclic stability and desirable rate capability. At 0.2 C rate, NiCo2S4nanotube array delivers the average discharge capacity of 720 mAh g−1during 50 cycles that slightly surpasses its theoretical capacity of 703 mAh g−1. When the current comes back to 0.2 C after rate measurements, NiCo2S4nanotubes can still stably deliver the discharging capacity of 652 mAh g−1, reaching 92.7% of that at the initial 0.2 C. Cyclic Voltammetry (CV) measurements reveal that NiCo2S4nanotube array contains two sets of electrochemical reaction behavior come from Ni and Co. The unique NiCo2S4nanotube array exhibits great potential as an anode material for high-performance Lithium-ion batteries.
