在过去的十年里，在理解电池运行的复杂动力学方面取得了重大进展。原位和操纵性实验技术的发展对于揭示电池系统中材料在充放电过程中如何变化、转化和降解至关重要。这一视角首先重点介绍了利用原位和操纵面实验来了解各种不同电池材料中的动力学的最新成功，包括合金/转换电极、插层电极和碱金属阳极。然后，我们讨论四个新出现的重点领域，在这些领域，原位和手术实验预计将产生影响。这些领域包括固态电池、改进的数据分析、跨时间和长度尺度的动态链接，以及了解InterPhase的原子尺度演变。我们预计，在研究电池系统在时间和长度尺度上复杂的内部工作方式方面的持续进展将有助于推动未来的电池技术。
Over the past decade, significant progress has been made toward understanding the intricate dynamics that underlie the operation of batteries. The development of in situ and operando experimental techniques has been critical for revealing how materials change, transform, and degrade within battery systems during charge and discharge. This Perspective first highlights recent successes in the use of in situ and operando experiments to understand dynamics in a variety of different battery materials, including alloy/conversion electrodes, intercalation electrodes, and alkali metal anodes. We then discuss four emerging focus areas in which in situ and operando experiments are expected to make an impact. These areas include solid-state batteries, improved data analytics, the linkage of dynamics across time and length scales, and understanding the atomic-scale evolution of interphases. We expect that continued progress in investigating the elaborate inner workings of battery systems across time and length scales will help to advance future battery technologies.
