The depleting fossil fuel reserves, high energy cost, climate change and the persistent production of materials that are irreversible in nature are encouraging the society to turn to energy sources that are renewable and sustainable. Although solar and wind energies are already introduced to lessen the dependence on nonrenewable energy sources, a number of this methods are still considered to be intermittent and unreliable sources because they are fully dependent on the characteristics of the weather.
One of the emerging technologies today are the new generation electrical energy storage systems (EESS). Storing the intermittent energy from the renewable natural energy resources through the use of EESS will lessen people’s dependence on fossil fuels and other nonrenewable energy sources. Activated Carbons (AC) are known to be one of the most functional material due to their wide range of applications, from gas adsorption to electrical energy storage systems, AC are surely in demand.
In this ultra-modern era of lifestyle, people are becoming more and more dependent on electricity to the point of making it an indispensable part of daily living. The study may pave the way for a viable alternative for energy storage devices which can in turn provide a higher capacitance while maintaining high efficiency with longer cycles. This alternative is ensured to be efficient, renewable, environmentally friendly and economical.
Up to now, a variety of carbon materials including graphene, carbon nanotubes, carbon aerogel, activated carbon and their composites, have been extensively employed as supercapacitors electrode materials owing to their large surface areas, high electrical conductivity, and good electrolyte contact, which facilitate rapid electron and ion diffusion. One material particularly heaves up- activated carbon, a material that has been the subject of intense interest owing to a number of advantages such as low cost and ease of fabrication from readily available natural biomass sources using simple activation routes. The realization of the quest for the synthesis of activated carbon, with all the properties appertaining for its conductive aspect may shed light in the realization of this research for supercapacitors.
