Electrochemical characterization of carbon nanotubes as electrode in electrochemical double-layer capacitors
TLDR
In this paper, carbon nanotubes uniformly 50 nm in diameter were grown on graphite foil, and cyclic voltammetry (CV) showed that the carbon-graphite foil electrode has a high specific capacitance (115.7 F/g at a scan rate of 100 mV/s) and exhibits typical double-layer behavior.About:
