The electrochemical performance of Co-OH/G and Co-OH is further compared to better understand the impacts of graphene in hybrids on energy storage. It is found that the Co-OH/G exhibits two more distinct pairs of redox peaks corresponding to equations (4), (5) respectively, implying a more significant Faraday process ( Fig. 4 c and …
Abstract. Energy consumption in the world has increased significantly over the past 20 years. In 2008, worldwide energy consumption was reported as 142,270 TWh [1], in contrast to 54,282 TWh in 1973; [2] this represents an increase of 262%. The surge in demand could be attributed to the growth of population and industrialization over …
