Abstract

Highlights

Metal-organic frameworks (UiO-66) functionalized glass fiber separator was constructed to accelerate the transport of charge carriers and provide a uniform electric field distribution on the surface of zinc anode.
Zinc anode demonstrates preferential orientation of (002) plane under the control of UiO-66-GF, which effectively inhibits dendrites.
Density functional theory calculation confirms that the adsorption effect of (002) plane on H is weaker, thus improving corrosion resistance and suppressing the hydrogen evolution reaction.
Symmetric cells exhibit highly reversible plating/stripping behavior with long cycle life over 1650 h and full cells demonstrate excellent long-term stability (85%) for 1000 cycles.

用于稳健锌离子水电池的金属有机框架功能化分离器

亮点构建了金属有机框架（UiO-66）功能化玻璃纤维分离器，以加速电荷载流子的传输，并在锌阳极表面提供均匀的电场分布。在 UiO-66-GF 的控制下，锌阳极显示出 (002) 面的优先取向，从而有效抑制了树枝状突起。密度泛函理论计算证实，(002) 平面对 H 的吸附作用较弱，从而提高了耐腐蚀性并抑制了氢演化反应。对称电池表现出高度可逆的电镀/剥离行为，循环寿命长达 1650 小时以上，全电池在 1000 次循环中表现出卓越的长期稳定性（85%）。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
