This monograph explores the current state of dielectric capacitors and electric double-layer supercapacitors, two increasingly important energy-storage technologies with a rapidly expanding range of applications. With a focus on materials science, the book delves into the critical requirements for electrode and electrolyte materials in these devices. It elucidates the underlying physical and chemical principles that guide the design of high-performance materials, emphasizing the crucial role of computational tools in accelerating the development cycle. The authors exemplify the importance of a comprehensive analysis of a material's potential energy landscape and critically evaluate in-silico techniques used to explore it. This analysis provides crucial insights into the mechanisms of charge storage, ion transport, and interfacial phenomena, ultimately enabling the prediction and optimization of device performance. By offering deep insights into the operational mechanisms of energy-storage devices, this monograph empowers researchers to make informed decisions in materials selection and design.
