How to increase energy storage capability is one of the fundamental questions, it requires a deep understanding of the electronic structure, redox processes, and structural evolution of electrode materials. These thorny problems now usually involve spin–orbit, spin-related electron configuration, etc., which cannot be probed using conventional testing techniques. Considering the intimate connection between spin and magnetic properties, using electron spin as a probe, magnetic measurements make it possible to analyze energy storage processes from the perspective of spin and magnetism. Owing to the capability of characterizing spin properties and high compatibility with the energy storage field, magnetic measurements are proven to be powerful tools for contributing to the progress of energy storage. In this review, several typical applications of magnetic measurements in alkali metal ion batteries research to emphasize the intimate connection between the magnetic properties and electronic structure, which is associated with the electrochemical performance of the electrode materials, are presented. Finally, the current challenges of magnetic measurements and the prospects for enhanced analysis of energy storage systems are discussed.

应用于储能的磁测量

如何提高储能能力是基本问题之一，需要对电极材料的电子结构、氧化还原过程和结构演化有深入的了解。这些棘手的问题现在通常涉及自旋轨道、与自旋相关的电子排布等，而这些问题无法使用传统的测试技术来探测。考虑到自旋与磁性之间的密切联系，以电子自旋为探针，磁测量使得从自旋和磁性的角度分析能量存储过程成为可能。由于具有表征自旋特性的能力以及与储能领域的高度兼容性，磁测量被证明是促进储能进步的有力工具。在这篇评论中，介绍了磁性测量在碱金属离子电池研究中的几种典型应用，以强调磁性特性和电子结构之间的密切联系，而电子结构与电极材料的电化学性能相关。最后，讨论了磁测量当前的挑战以及增强能量存储系统分析的前景。
