Research progress of textile-based zinc ion battery

摘要:

水系锌离子电池(ZIBs)在安全性和规模化生产应用方面拥有广阔的前景,但正极和负极的能量密度和循环寿命较低阻碍了ZIBs的实际应用。而以纺织材料为基材的电极具有高导电性、化学稳定性和易与其它活性物质负载的特点,能有效解决上述问题。本文从纤维状到平面状两个角度对柔性锌离子电池的最新研究进展进行总结,阐明柔性锌离子电池构筑的可行性方法,明确电池正极材料反应动力学与电极结构、表面特性及活性材料复合条件的构效关系。最后,针对纺织基锌离子电池发展存在的问题进行说明并对未来需要攻克的重点难点进行分析及展望。

Abstract:

Aqueous zinc ion batteries (ZIBs) hold great promise for safety and large-scale production applications, but the low energy density and cycle life of the anode and cathode electrodes hinder the practical application of ZIBs. The electrodes based on textile materials have high electrical conductivity, chemical stability and easy loading with other active substances, which can effectively solve the above problems. This paper summarizes the latest research progress of flexible Zn-ion batteries from two perspectives, from fibrous to planar, to elucidate the feasible methods for the construction of flexible Zn-ion batteries, and to clarify the conformational relationships between the reaction kinetics of the cathode material and the electrode structure, surface properties and active material compounding conditions of the batteries. Finally, the problems in the development of textile-based zinc ion batteries are explained and the key challenges to be overcome in the future are analyzed and foreseen.
