纺织基柔性锌离子电池的研究进展

Research progress on textile-based flexible zinc ion batteries

水系锌离子电池(ZIBs)在安全性和规模化生产应用方面具有广阔的前景,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他活性物质负载的特点,能有效解决上述问题。该文以纺织视角阐述现阶段纺织类柔性锌离子电池的研究进展,以纤维状锌离子电池和平面结构型锌离子电池两个维度对柔性锌离子电池进行总结,明确两种类型柔性锌离子电池正极材料的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。

Aqueous zinc ion batteries(ZIBs)shows great potential in safety and large-scale production applications,however,the low energy density and short recycle life of the electrodes limits their practical applications.Textile based electrodes possess high electrical conductivity,chemical stability and could be easily loaded with other active substances,which can effectively overcome the above mentioned limitations.In this review,the latest research progress on flexible textile based Zn-ion batteries were described from textile perspective,followed by summarization on the batteries with fibrous and planar structures as well as the conformational relationships between reaction kinetics of anode material and electrode structure,surface properties and active material compounding conditions.Finally,the existing problems and the challenges in the development of textile-based zinc ion batteries were explained and analyzed.
