印刷和涂布MXene油墨用于电化学储能器件

MXene Inks for Printing and Coating of Electrochemical Energy Storage Devices

人们对电子设备的不断增长的需求促使行业亟需开发新型、低成本和高产量的制造方法。油墨印刷和涂布是一种很有潜力的技术,可规模化制备微型电子器件。然而,功能性油墨的缺乏使得柔性电子的规模化印刷打印受到极大的制约。MXenes,作为一种新型二维材料,由于其出色的化学、电气、光学和机械性能,迅速受到了研究者的极大关注。其丰富的官能团,表面电荷、本征亲水特性使得高浓度的MXene油墨具有优异的胶体稳定性,因此,MXene成为功能性油墨配方的最佳选择。在MXene所报道的电子器件应用中,电化学储能器件是研究最为热门的领域。为此,简要介绍了MXenes及其合成方法之后,讨论了油墨的配方策略,并回顾了一些基于MXenes印刷和涂布构筑高性能电化学储能器件方面的最新工作。为后续MXene用于规模化电化学储能器件的制造提供思路。

The ever-increasing demand for electronic devices has motivated the industry to opt for new,cost-effective and high throughput manufacturing methods.Printing and coating are promising techniques with potential to meet such demands.However,so far,their progress has been limited by the lack of functional inks.MXenes,recently emerged new two-dimensional materials,could be a true game-changer,due to their outstanding chemical,electrical,optical and mechanical properties.Abundant functional groups,rich surface chemistry and exceptional colloidal stability even at very high concentrations make MXenes a perfect choice for functional ink formulation.While MXenes have been demonstrated to have excellent performance in almost all electronic devices in one way or another,their largest application field is in the energy storage devices.In this contribution,after a brief introduction on MXenes and their synthesis methods,we discuss ink formulation strategies and review some of the latest works on printing and coating of MXene-based electrochemical energy storage devices.This perspective is to shed light on the efficient fabrication of high-performance energy-storage devices based on functionalized MXene inks and provide guidelines to the processing of MXene materials.
