EXTENDED ABSTRACT: The development of safe high-energy-density electrochemical energy storage devices is crucial for economic and environmental concerns, with a key scientific challenge being how to enhance the understanding and design capabilities of batteries. The interface between electrodes and electrolytes, where electrochemical energy storage reactions occur, plays a vital role in the design and control of battery pe改Jrmance. This report begins by addressing the electrochemical theoretical requirements of electrolytes and electrodes, designing the components and structures of the electrode-electrolyte interface using microscopic techniques, and controlling the thermodynamics and kinetics of reactions at the electrodeelectrolyte interface to enhance electrochemical models. By combining research cases on the development of electrolyte additives for magnesium metal batteries and the suppression of dendrite formation in all-solid-state lithium metal batteries, this study demonstrates the guiding significance of electrochemical models and multiscale computations in electrolyte material adaptation and microstructure design of electrodes. Additionally, it provides an outlook on the potential applications of electrochemical models and materials computation in the development of future electrochemical energy storage devices. Keywords: Battery; Multiscale computations; Interface; Electrolyte
