摘　　要：纳米技术在能源领域的应用为解决化石燃料的消耗和环境污染问题提供了新的契机.水滑石(LDHs)作为一类典型的阴离子黏土材料,其独特的组成、结构及形貌可调性,使其成为一类优秀的能源储存和转化材料.其中,将水滑石材料进行纳米阵列结构化设计,结合水滑石优异的物理化学性能和纳米阵列的结构特性,已经成为构建高性能电化学电极的重要方法.本文综述了水滑石基纳米阵列电极的合成及其在电化学能量储存和转化上的应用,并进一步讨论了水滑石纳米阵列材料在该领域面临的挑战和发展趋势.The development ofnanotechnology in recent decades has brought new opportunities in the exploration of new materials for solving the issues of fossil fuel consumption and environment pollution. Layered double hydroxides （LDHs）, as a typical class of anionic clays materials, display large potential in electrochemical energy storage and conversion due to the facile tunability of their composition, structure and morphology. Furthermore, nanoarray architecture design of LDHs, combining the excellent intrinsic physico-chemical properties of LDHs and structural advantages ofnanoarrays, is emerging as a key strategy to fabricate high-performance electrochemical electrodes. This review summarizes the latest developments in the preparation and evaluation of LDH materials toward electrochemical energy storage and conversion. Furthermore, current challenges and future strategies are proposed from the viewpoint of material design and practical application of LDHs nanoarray electrodes.
