Recent advancement in the graphene derived materials for electrochemical supercapacitors
摘要
One of the most intense concerns of the twenty-first century has become the energy crisis, its global importance is evident from the very fact that the seventh goal out of the seventeen SDG goals is dedicated to affordable and clean energy. Meeting the energy demand is one perspective, the most important mandate is producing clean and affordable energy. Energy production is very important, so much so is energy storage. The present review specifically focuses on supercapacitors and touched on the graphene related achievements. Inputs from graphene polymer nanocomposites towards supercapacitors have been discussed. Nanocomposite supercapacitors composed of graphene and electrically conducting polymers such as polyaniline (PANi), polypyrrole (PPy), poly(3,4- ethylenedioxythiophene) (PEDOT), poly(thiophene) (PTh), and poly(hexylthiophene) (PHTh) and their significant contributions to supercapacitors has been presented. The review points out to the fact that few authors have pointed out to the challenges and limitations of this otherwise highly promising graphene polymer supercapacitors and fewer still have ventured to address the challenges and combat the limitations. The lapses in technology transfer from research to the supercapacitor industry has also been highlighted and motivation in this direction prompted. The salient features of these discussions have been summarized in this review.
