Abstract The poor cycling life hindered the progression of aqueous nickel-based batteries. Herein, a facile electrodeposition approach was employed to design a three-dimensional lamellar Bi anode (TL-Bi) on nickel foam with a long-term cycling stability for rechargeable aqueous Ni//Bi batteries. The areal capacity of the TL-Bi electrode was 0.19 mA h cm−2 at 4 mA cm−2 in a three-electrode system. Also, the fabricated Ni//Bi battery constituted through an as-obtained TL-Bi anode and a NiO cathode delivered an excellent power density specific capacity of 14.4 mW cm−2 and exceptional durability (retaining 94.1% after 4500 cycles) in an aqueous electrolyte. With the merits of safe and easy to operate, this simple available pressing method may inspire new development for reversible aqueous batteries.

长寿命水系镍铋电池晶体铋三维有序结构的构建

摘要 循环寿命差阻碍了水性镍基电池的发展。在此，采用简便的电沉积方法在泡沫镍上设计了具有长期循环稳定性的三维层状 Bi 阳极（TL-Bi），用于可充电水性 Ni//Bi 电池。在三电极系统中，TL-Bi 电极的面积容量在 4 mA cm-2 时为 0.19 mA h cm-2。此外，通过所获得的 TL-Bi 阳极和 NiO 阴极构成的制造的 Ni//Bi 电池提供了 14.4 mW cm-2 的优异功率密度比容量和优异的耐久性（4500 次循环后保持 94.1%）在水电解质。凭借安全和易于操作的优点，这种简单可用的压制方法可能会激发可逆水性电池的新发展。
