Structure, dynamics and electrochemical stability of concentrated electrolytes in confined spaces

该合作项目旨在了解密闭空间中浓缩电解质的结构和动力学，以及它们对电池系统电化学稳定性，电荷转移动力学和整体性能的影响。这些系统在高度复杂的受限条件下运行，使它们远离平衡，反应速率和传输现象之间存在耦合。由于高电压稳定性和高阳离子迁移数等有前途的特性，最近人们开始探索高浓度电解质。使用实验，理论和模拟，我们将探索从分子限制（间隙<1 nm）到体积（间隙~微米）的电解质行为的结构和动力学，并将这些特征与其整体反应性联系起来，这控制了电池性能的一个重要方面（极端电压下的稳定性）。

This collaborative project aims to understand the structure and dynamics of concentrated electrolytes in confined spaces, and their impact on electrochemical stability, charge transfer kinetics and overall performance in battery systems. These systems operate under highly complex confined conditions, making them far-from-equilibrium with coupling between reaction rates and transport phenomena. Highly-concentrated electrolytes have recently been explored due to promising properties, including high voltage stability and high cation transference numbers. Using experiments, theories and simulations, we will probe the structure and dynamics of electrolyte behavior from molecular confinement (gap <1 nm) to bulk (gap ~microns), and connect these characteristics to their overall reactivity, which controls an essential aspect of battery performance (stability at extreme voltages).
