Description

Supercapacitors (SCs), also known as electrochemical capacitors, have gained increasing attention as advanced energy storage devices due to their high-power density, rapid charge–discharge capability, and long cycle life. However, their relatively low energy density compared with batteries remains a key limitation. Recent research has focused on improving electrode materials, electrolytes, and device configurations to overcome these challenges. This review summarizes recent advances in supercapacitor technology, emphasizing electrode material development, electrolyte innovations, novel device architectures, and emerging research trends. The challenges and future prospects of supercapacitors are also discussed.
