Abstract

The rising worldwide demand for energy storage devices has driven significant advancements in studies regarding supercapacitor (SC), particularly in the context of renewable green energy systems and electronics. SCs have come up as a critical technology, providing ultra-fast charging, long lifespan and high-power density when compared to conventional batteries. These attributes make SCs ideal for applications that needs surging energy delivery, such as electric vehicles and grid energy storage systems. Lately wide range of research has been focused on enhancing the energy density through the development of advanced evolved materials and device architectures. This review article discusses recent advancements in SC, particularly in electrode materials, such as transition metal oxides (e.g., RuO2, MnO2, V2O5) and metal chalcogenides (e.g., MoS2), which exhibit high surface area, great electrical conductivity, and mechanical stability. These materials, alongside carbon-based materials like graphene and conducting polymers, have demonstrated significant improvements in charge storage capacity and energy transfer efficiency. Hybrid materials containing metal oxides with carbon-based contents have shown great promise in enhancing both energy and power densities. The review also discusses recent trends in electrolytes, including ionic liquids, aqueous solutions, and solid-state electrolytes, which have played significant role in improving SC performance by widening the voltage window and enhancing stability. Despite these technological advancements, challenges such as cost-effective material production and scalability remain barriers to widespread commercialization. The customization of SCs into hybrid energy storage systems alongside batteries and fuel cells presents a promising avenue for future development. This review article pins down the importance of ongoing research to overcome these challenges while fully realizing the potential of SCs in the evolving energy landscape.
