ABSTRACT This study investigates the advancement of coin cell supercapacitors (SCs) for sustainable, high‐performance energy storage by employing biomass‐derived date stone activated carbon with various ionic liquid (IL) electrolytes at different temperatures. The research reveals that SCs demonstrate both pseudocapacitive and electrochemical double‐layer characteristics. Among tested ILs, 1‐Butyl‐3‐methylimidazolium trifluoromethanesulfonate (BMIMOTf) emerges as most effective, achieving an impressive density 129.9 Wh kg −1 , a power 403.8 W specific capacitance 103.9 F g 0.5 A − 1 . After 5000 cycles, supercapacitor utilizing BMIMOTf maintains 97.3% its initial exhibits Coulombic efficiency approaching 100%. Additionally, temperature‐dependent analyses from room temperature to 50°C reveal higher temperatures boost performance SC, attributed improved conductivity. offers more comprehensive understanding how materials interact, emphasizing capacity foster innovations in eco‐friendly solutions.

Supercapacitors are promising energy storage devices that combine high power density, fast charge/discharge rates, and excellent cycling stability. However, their relatively low density compared to batteries remains a major challenge. To address this limitation, redox additive electrolytes have emerged as key strategy introduce reversible Faradaic reactions, significantly enhancing the capacity of supercapacitors. This mini-review systematically summarizes recent advancements in use redox-active species across aqueous, non-aqueous, solid-state/gel electrolytes. We highlight role both inorganic organic additives, detailing mechanisms, advantages, limitations improving Furthermore, we discuss challenges associated with species, such solubility, long-term stability, parasitic side which hinder practical applications. Future research directions proposed optimize materials electrolyte systems, aiming develop next-generation supercapacitors superior extended life, enhanced applicability.

Because of safety concerns associated with the use liquid electrolytes and electrolyte solutions, options for non-liquid materials like gels polymers to be used as ion-conducting have been explored intensely, they attract steadily growing interest from researchers. The low ionic conductivity most hard soft solid was initially too practical applications in supercapacitors, which require internal resistance a device and, consequently, highly conducting materials. Even if an additional separator may not needed when already ensures reliable separation electrodes, prepared films or membranes thin practically acceptable, still high even today. Recent developments gel sometimes approach surpass terms effective conductance. This includes based on biopolymers, renewable raw materials, biodegradability, better environmental compatibility. In addition, numerous approaches improving electrolyte/electrode interaction yielded improvements resistance. Reported studies are reviewed, material combinations sorted out, trends identified.
