摘要

在这项工作中，双金属氢氧化物(Ni和Co)电化学沉积在飞秒激光诱导的Ni箔上，作为水可充电的Ni/ Zn电池阴极(记为LNF@NiCo-OH)。采用fs激光制备的Zn作为阳极(记为LZF)。所制备的Ni/ Zn电池(表示为LNF@NiCo-OH//LZF)具有优异的循环性能(20000次充放电循环后容量无衰减)，超高的能量密度(0.782 mW h cm−2)和功率密度(80.25 mW cm−2)。这些优点可以使所获得的Ni/ Zn电池满足下一代储能设备的需求。

Micro/Nanostructured Cathode and Anode Induced by Femtosecond Laser for Ni//Zn Battery

In this work, bimetallic hydroxide (Ni and Co) was electrochemically deposited on femtosecond laser-induced Ni foil as aqueous rechargeable Ni//Zn battery cathode (denoted as LNF@NiCo-OH). The fs laser fabricated Zn was used as anode (denoted as LZF). The obtained Ni//Zn battery (denoted as LNF@NiCo-OH//LZF) could deliver outstanding cycling performance (no capacity decay after 20000 charge-discharge cycles), ultrahigh energy density (0.782 mW h cm−2) and power density (80.25 mW cm−2). These advantages may endow the obtained Ni//Zn battery to meet the demand of next-generation energy storage devices.
