This thorough review article offers a cutting-edge analysis of the essential characteristics and developments in electrode materials and electrolytes for supercapacitor technology. We start by going over the basics of supercapacitors and how important characterization methods like electrochemical impedance spectroscopy, galvanostatic charge-discharge, and cyclic voltammetry work. Specific capacitance, energy, and power densities, three essential characteristics that are crucial for assessing supercapacitor performance, are carefully covered in this work. We also analyze the many kinds of capacitors, including hybrid supercapacitors, electric double-layer capacitors, pseudocapacitors, and supercapacitors, and explain their working principles and material-specific characteristics. The study highlights the importance of metal oxides and hydroxides, carbon-based materials, conductive polymers, and novel and hybrid materials such as MXenes and metal-organic frameworks. The special qualities of each material class, such as large surface area, electrical conductivity, and particular redox properties, are highlighted in this section. These qualities are crucial for maximizing the performance of supercapacitors. The topic of electrode materials is discussed in detail, including their benefits and the difficulties and chances to improve energy storage, stability, and affordability. Parallel to this, the study thoroughly examines various electrolyte kinds, a sometimes overlooked yet essential part of supercapacitor technology. Discussed include ionic conductivity, operating voltage windows, safety profiles, and electrochemical stability of aqueous, organic, ionic liquid, gel, and solid-state electrolytes. This paper highlights the relationship between supercapacitor performance and electrolyte type, explaining how electrolyte selection affects total energy density, power density, and operational longevity. This review article covers supercapacitor technology in detail and with a wide scope and is an invaluable resource. It is a fundamental work for scholars and practitioners new to the area. It offers sophisticated insights that may encourage creativity and application-specific advancement in this quickly changing field. The study presents a comprehensive analysis of the present and future developments in supercapacitor materials and technology, establishing it as a vital resource in the continuous search for cutting-edge energy storage solutions.

The development of efficient supercapacitors hinges on the innovation of superior electrodes, which are pivotal in augmenting their energy storage capabilities. Supercapacitors, recognized for their high‐power density and extended cycle life, play a crucial role as sustainable solutions in addressing energy storage challenges. A fundamental aspect of supercapacitor functionality involves the electrode material, which works in concert with other key components such as the current collector, separator, and electrolyte. This study focuses on evaluating the impact of the current collector material on the performance of symmetric supercapacitors. We investigated the electropolymerization of polyaniline on woven steel mesh current collectors of varying mesh sizes, ranging from 20 to 200 mesh per inch, using assorted deposition conditions. The electrochemically modified woven steel meshes were utilized to construct symmetric supercapacitors. The electrochemical performance of the assembled supercapacitors, configured in a two‐electrode system, was investigated using a variety of electrochemical techniques to better understand the kinetics of electrolyte ion migration. Notably, the 20‐mesh size, characterized by the fewest pores per inch, demonstrated superior performance with an optimum capacitance of 4730 mF/cm2, an energy density of 317.8 µWh/cm2, and a power density of 400 µW/cm2 at a current density of 1 mA/cm2.
