We report the synthesis of three-dimensional (3D) urchin-like NbO microstructures by a facile hydrothermal approach with subsequent annealing treatment. As anode materials for lithium-ion batteries, the 3D urchin-like NbO microstructures exhibit superior electrochemical performance with excellent rate capability as well as long-term cycling stability. The electrode delivers high capacity of 131 mA h g after 1000 cycles at a high current density of 1 A g. The excellent electrochemical performance suggests the 3D urchin-like NbO microstructures may be a promising anode candidate for high-power lithium ion batteries.
我们通过简便的水热法并随后进行退火处理,合成了三维(3D)刺猬状 NbO 微结构。作为锂离子电池的阳极材料,3D 刺猬状 NbO 微结构具有优异的倍率性能和长期循环稳定性,表现出卓越的电化学性能。该电极在 1 A g 的高电流密度下循环 1000 次后,仍能提供 131 mA h g 的高容量。优异的电化学性能表明,3D 刺猬状 NbO 微结构可能是高功率锂离子电池有前途的阳极候选材料。
