Depth analysis of supercapacitor
Super capacitor: also known as electrical double layer capacitor, electrochemical capacitor (EC), gold capacitor, farad capacitor, etc. The energy storage mechanism of supercapacitor was discovered by Helmholz in 1879. In 1947, Graham et al. First began to study the electrocapillary phenomenon of mercury. In 1957, Becker first proposed that smaller capacitors can be used as…
