碳纳米管被认为是制造高性能锂电池最有前途的材料之一。这一前景与碳纳米管宏观结构的构建密切相关。超对准碳纳米管(SACNT)阵列是一种独特的垂直排列碳纳米管阵列。它的高度定向性和强大的管内力有利于制备各种形式的宏观SACNT结构，包括单向薄膜、巴氏薄膜和气凝胶等。所制备的SACNT宏观结构因其优异的电学和力学性能而被成功地引入锂电池。本文综述了宏观碳纳米管在锂电池中的作用，包括在复合电极、集电体、中间层和柔性全电池中的应用。
Carbon nanotubes (CNTs) are regarded as one of the most promising materials to manufacture high‐performance lithium batteries. This prospect is closely related to the construction of macroscopic architectures of CNTs. The superaligned CNT (SACNT) array is a unique kind of vertically aligned CNT array. Its highly oriented feature and strong intertube force facilitate the fabrication of macroscopic SACNT structures with various forms, including unidirectional films, buckypapers, and aerogels, etc. The as‐produced SACNT macroscopic architectures are successfully introduced into lithium batteries due to their outstanding electrical and mechanical properties. Herein, an overview of the functions of macroscopic SACNTs in lithium batteries is proposed, including their applications in composite electrodes, current collectors, interlayers, and flexible full cells.
