Significant progress has been made in recent years in theoretical modeling of the electric double layer (EDL), a key concept in electrochemistry important for energy storage, electrocatalysis, and multitudes of other technological applications. However, major challenges remain in understanding the microscopic details of the electrochemical interface and charging mechanisms under realistic conditions. This review delves into theoretical methods to describe the equilibrium and dynamic responses of the EDL structure and capacitance for electrochemical systems commonly deployed for capacitive energy storage. Special emphasis is given to recent advances that intend to capture the nonclassical EDL behavior such as oscillatory ion distributions, polarization of nonmetallic electrodes, charge transfer, and various forms of phase transitions in the micropores of electrodes interfacing with an organic electrolyte or ionic liquid. This comprehensive analysis highlights theoretical insights into predictable relationships between materials characteristics and electrochemical performance and offers a perspective on opportunities for further development toward rational design and optimization of electrochemical systems.

了解双电层结构、电容和充电动力学
近年来，双电层 (EDL) 的理论建模取得了重大进展，EDL 是电化学中对储能、电催化和许多其他技术应用很重要的关键概念。然而，在实际条件下理解电化学界面和充电机制的微观细节仍然存在重大挑战。本综述深入探讨了描述 EDL 结构和电容的平衡和动态响应的理论方法，用于通常用于电容储能的电化学系统。特别强调旨在捕捉非经典 EDL 行为的最新进展，例如振荡离子分布、非金属电极的极化、电荷转移、以及与有机电解质或离子液体接触的电极微孔中的各种形式的相变。这种综合分析突出了对材料特性和电化学性能之间可预测关系的理论见解，并为进一步发展合理设计和优化电化学系统提供了机会。
