摘要:

膨润土是一种储量丰富、廉价易得的天然黏土矿物, 其主要矿物成分为蒙脱石(MMT)。MMT因独特的二维层状纳米结构、丰富的孔隙结构和高比表面积而具有良好的离子交换性能、吸附性能和离子传输性能, 而且热稳定性、化学稳定性和机械稳定性优异。近年来, MMT因上述特性, 特别是其固有的金属离子(Li+、Na+、Zn2+等)传输特性, 引起了电化学储能领域研究人员的关注并被广泛用于电化学储能装置的关键部件(电极、聚合物电解质和隔膜), 展现出了良好的应用前景。本文首先概述了膨润土的结构及理化特性, 然后详细综述了膨润土基功能材料在电化学储能装置(主要包括金属负极、锂硫电池正极、固态/凝胶聚合物电解质、聚合物隔膜)中的应用研究进展, 在此基础上重点阐述了膨润土基功能材料在电化学储能过程中促进离子传输的作用机理。最后总结了当前膨润土基功能材料在电化学储能装置领域所面临的问题和挑战, 并对未来的研究方向进行了展望, 以期为今后设计开发膨润土基电化学储能功能材料提供有益指导。

Abstract:

Bentonite is an abundant, cheap and readily available natural clay mineral, with montmorillonite (MMT) as its main mineral composition. MMT possesses excellent ion exchange, adsorption and ion transport properties due to its unique two-dimensional layered nanostructure, abundant pore structure, and high specific surface area. Moreover, it also possesses excellent thermal, chemical and mechanical stabilities. In recent years, MMT has attracted extensive attention in the field of electrochemical energy storage owing to the above excellent characteristics, especially the inherent fast ion (Li+, Na+, Zn2+, etc.) transport properties. Thus, the bentonite-based functional materials have been widely applied to the key components (i.e., electrodes, polymer electrolytes, and separators) of electrochemical energy storage devices and show good application prospects. In this review, the structure and physicochemical properties of bentonite are firstly introduced, and then the research progress of bentonite-based functional materials in the field of electrochemical energy storage, mainly including metal anodes, lithium-sulfur battery cathodes, solid/gel polymer electrolytes, and polymer separators, is comprehensively summarized. On the basis of these facts, the ion transport promotion mechanism of bentonite-based functional materials during the process of electrochemical energy storage is elaborated. Finally, the current problems and challenges faced by application of bentonite-based materials in electrochemical energy storage devices are pondered, and the possible future research directions are prospected. This review provides useful guidance for the design and development of bentonite-based electrochemical energy storage functional materials.
