Abstract Nickel vanadate (Ni3V2O8, NVO) nanoparticles (NPs) with a typical size of 30 nm were prepared through a zeolitic imidazolate framework (ZIF) intermediate precipitation method using water as a solvent. The intermediate and the NVO obtained after annealing the intermediate were systematically characterized using various techniques. When tested as an anode for Li-ion batteries (LIBs), the electrode displayed stable specific capacities of 940 and 305 mA h g− 1 at 1 and 5 A g− 1, respectively, after 400 and 1000 cycles. Additionally, a very high reversible capacity of 1024 mA h g− 1 was observed after 525 cycles, during which high current densities of 2 and 0.5 A g− 1 alternated every 100 cycles. The long cycling rate capability with repeated sets, confirm the structural stability of the material, which was prepared through a facile and eco-friendly procedure.

Ni 3 V 2 O 8 纳米粒子作为高能锂离子电池的优良负极材料

摘要 以水为溶剂，通过沸石咪唑骨架（ZIF）中间沉淀法制备了典型尺寸为30 nm的钒酸镍（Ni3V2O8，NVO）纳米颗粒（NPs）。中间体和中间体退火后获得的 NVO 使用各种技术系统地表征。当作为锂离子电池 (LIB) 的阳极进行测试时，电极在 400 和 1000 次循环后分别在 1 和 5 A g-1 下显示出 940 和 305 mAh g-1 的稳定比容量。此外，在 525 次循环后观察到 1024 mAh g-1 的非常高的可逆容量，在此期间，2 和 0.5 A g-1 的高电流密度每 100 次循环交替。具有重复组的长循环率能力，确认材料的结构稳定性，
