论文摘要
锂金属固定状态电解质界面在固态电池的性能中起着至关重要的作用。但是，由于缺乏直接的光学访问，固态细胞中埋入界面形态的操作数特别困难。需要无意中隔离接口的破坏性技术会修改接口，并且不能用于操作。在这项工作中，我们使用经过改进的3-员道传感器介绍了热波传感的概念，该传感器附着在锂金属 - 固态细胞的外部，以非敏感性探测锂金属电解质界面的形态。我们表明，由3-欧年传感器测量的热界面电阻直接与界面的物理形态有关，并证明3-欧洲热波传感可用于非侵入性操作，以监测锂金属醇酸盐态电解质电解质界面的形态演化。
The lithium metal-solid-state electrolyte interface plays a critical role in the performance of solid-state batteries. However, operando characterization of the buried interface morphology in solid-state cells is particularly difficult because of the lack of direct optical access. Destructive techniques that require isolating the interface inadvertently modify the interface and cannot be used for operando monitoring. In this work, we introduce the concept of thermal wave sensing using modified 3-omega sensors that is attached to the outside of the lithium metal-solid state cells to non-invasively probe the morphology of the lithium metal-electrolyte interface. We show that the thermal interface resistance measured by the 3-omega sensors relates directly to the physical morphology of the interface and demonstrate that 3-omega thermal wave sensing can be used for non-invasive operando monitoring the morphology evolution of the lithium metal-solid state electrolyte interface.
