摘要

碱金属电池具有未来设备所需的高能量密度；然而，金属沉积不均匀是实现长寿命的关键障碍。我们开发了一种优雅的非致冷透射电子显微镜方法，有助于首次观察碱金属电池中的外延沉积。利用这种方法，我们证实了锌集流体中 (002) 钠晶粒平面和 (01-11) 平面之间的外延相互作用。这种外延相互作用降低了成核能量障碍，促进了金属的均匀生长。这项研究为开发针对电子敏感电池材料的电子显微镜技术提供了新的灵感，并为电池技术的发展设定了新的议程。

Revealing Epitaxial Deposition in Alkali Metal Batteries

Alkali metal batteries have high energy densities required to power future devices; however, uneven metal deposition is a critical barrier to achieving long lifespans. We have developed an elegant noncryogenic transmission electron microscopy method which has facilitated the first observations of epitaxial deposition in alkali metal batteries. Using this method, we have confirmed epitaxial interactions between (002) sodium crystallite planes and (01–11) planes in zinc current collectors. Such epitaxial interactions decrease nucleation energy barriers and promote even metal growth. This study offers fresh inspiration for the development of electron microscopy techniques tailored to electron-sensitive battery materials and sets a new agenda for the development of battery technologies.
