Supercapacitors and Their Applications: Fundamentals, Current Trends, and Future Perspectives

Supercapacitors are energy storage devices that can store and release large amounts of power quickly. They are made up of two or more electrodes that are separated by an electrolyte. When charged, the electrodes attract electrons, which creates a capacitive effect. Supercapacitors can be charged and discharged thousands of times, making them ideal for applications such as electric vehicles, renewable energy systems, and backup power.

Supercapacitors, also known as electrochemical double-layer capacitors (EDLCs), have gained significant attention in recent years due to their remarkable capabilities in energy storage and power management applications. In this comprehensive review, we will delve into the fundamental principles of supercapacitors, their working concepts, and design. We will explore various characterization and modeling techniques employed to understand the behavior and performance of these devices. Special emphasis will be placed on the application of supercapacitors in critical areas such as environmental sustainability and social impact.

Characterization techniques play a vital role in understanding the characteristics of supercapacitors. Cyclic voltammetry (CV), charging-discharging curves, and electrochemical impedance spectroscopy (EIS) are among the commonly used methods to evaluate their electrochemical properties. CV measures the voltage change during the charging and discharging processes, while charging-discharging curves provide insights into the energy storage capacity and power density of the devices. EIS measures the resistance and capacitance of the supercapacitor at different frequencies, allowing for a comprehensive analysis of their electrical behavior.

A detailed chapter will be devoted to discussing the historical perspectives on the evolution of supercapacitors. From the initial discoveries in the 1970s to the recent advancements in materials and manufacturing processes, supercapacitors have undergone a remarkable transformation. This chapter will highlight the key milestones and contributions that have propelled the development of this technology.

In conclusion, this review provides an in-depth look at supercapacitors, including their working concepts and design. It reviews detailed explanations of various characterization and modeling techniques, with a special focus on the application of supercapacitors in major areas of environmental and social importance. The historical perspectives on the evolution of supercapacitors add valuable insights into the progress made in this field. By understanding the characteristics and applications of supercapacitors, we can continue to explore new opportunities for energy storage and power management in various industries.
