This paper presents a review of the recent advances of the supercapacitors energy storage systems. The recent development of the supercapacitors devices is presented and discussed. The need for highly dependable backup and emergency power is fueling growth in the energy storage and power transmission industries. One of the most advanced types of energy storage devices is the supercapacitor. At the electrode-electrolyte interface, these supercapacitors can store electrical charge in an electric double layer. Different materials are considered for creating the supercapacitors, such as graphene, carbon black, and charcoal. This paper focuses on the electrode material, rare earth and their composites-based electrode materials for supercapacitors, atomic layer deposition in the development of transition-metal-oxide and conducting polymer-based fibers for supercapacitors, and atomic layer deposition in the development of transition-metal-oxide and conducting polymer-based fibers for supercapacitors.
