在过去的三十多年里，锂离子电池已经彻底改变了我们储存和运输能源的方式。这些令人难以置信的紧凑的电化学装置从根本上依赖于可逆地将锂离子插入密集排列的原子中的能力。在结构数据库中报告的成千上万种材料中，只有极少数材料被证明能够适应在实际设备中操作所必需的那种快速离子扩散。为了纪念John B. Goodenough的100岁生日，这篇文章将概述目前对各种结构特征的理解，这些结构特征有助于和/或损害锂离子通过插入宿主的快速运输，特别关注刚性亚基的旋转在锂通过固态运动中的作用。
Over the course of more than three decades, Li-ion batteries have come to revolutionize the way we store and transport energy. These incredibly compact electrochemical devices rely fundamentally on the ability to reversibly insert lithium ions into densely packed arrangements of atoms. Of the tens of thousands of materials reported in the structural databases, only a very small number have been shown to be capable of accommodating the kind of fast ionic diffusion necessary to operate in practical devices. In honor of John B. Goodenough's 100th birthday, this perspective will overview the current understanding of the kinds of structural features that help and/or hurt fast lithium ion transport through insertion hosts, with a particular focus on the role that the rotation of rigid subunits plays in the movement of lithium through the solid state.
