ABSTRACT
The design, operation, and manufacturing of electrochemical Electrochemical Supercapacitor (ES) devices are important in supercapacitor technologies. However, the industry advancements of electrode fabrication and materials design largely remain proprietary to individual developers and manufacturers. In ES design and manufacturing, other factors related to the operation should be considered: unforeseen voltage spikes, electrolyte decomposition, effects of applying excessive voltage, and cell performance decay. A large number of carbon materials have been developed in recent years in an effort to improve the performance of ES electrode materials. Among carbon materials, activated carbon-based materials remain the predominant choices for electrode production due to low cost and good cycle lives. Three ways to assemble the electrode layer and current collector are: bind the previously prepared electrode layer film onto the current collector, deposit the electrode layer onto the current collector, and spray the electrode layer onto the current collector.
