Abstract
Energy is essential for human enhancement and is used 24 h a day. Nonrenewable and renewable energy sources meet global demands and reduce economic challenges. Supercapacitors offer higher power density, high capacitance value, temperature tolerance, and long-term durability than other energy storage devices. Supercapacitors are used in various applications, including transportation (hybrid vehicles, electric vehicles), automotive, and renewable energy. Electrode materials play a crucial role in supercapacitors’ performance, with transition metal-based materials like transition metal oxides (TMOs), transition metal sulfides (TMS), and transition metal nitrides (TMN) being popular due to their high specific energy output and chemical stability. This review highlights hybridization and performance enhancement of TMO-carbon composites for supercapacitor applications. Emphasis is placed on synergistic interactions that improve charge storage mechanisms, energy density, and cycling stability. Additionally, we discuss applications like hybrid energy storage (HES) systems to improve travel range by integrating batteries with supercapacitors to create a hybrid energy storage system, which is another possibility for providing high current, increasing battery life in electric vehicles, challenges, other promising materials for electrodes, fabrication methods, and future perspectives toward scalability.
期刊介绍:
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
