Commercially Available Supercapacitors –A Perspective on Global, African and Nigerian Markets

Supercapacitors are considered as promising energy storage devices for their remarkable properties.This makes their global market on constant improvement over the last decade, with the potential to have more market share. As more and more Supercapacitors (SCs) are becoming commercially available, we need to have their representative for comparing other newly developed technology. Achieving this involves studying their behaviors through simulations, experiments or combined approach.However, thisis time consuming if we consider simultaneous comparison of many SCs, since different technologies are available. Thus, there is the need to have a compilation of the SC technologies/manufacturers,as this information could easily help to compare and hence choose the most widely accepted technology.To meet this need, the study takes review approach through survey of relevant literatures and come up with the collation.The study considers commercial supercapacitors in the global, African and Nigerian markets,as the product availability from a given company, in these regions, is a mark of acceptance, robustness, and hence originality. The study identifies Maxwell technology to havemarket dominance over the three classified regions of consideration, followed by the Eaton technology which dominates two of the regions.Hence, based on the result of this study, Maxwell and Eaton SCs could be adopted as the standard technologies for comparingother and newly developed products.
