文摘
- •
Electrochemical properties of commercialized activated carbon, graphene, and singlewalled carbon nanotube are investigated
- •
Correlations are identified between capacitive and resistive behaviors and representative porous structures including morphology, surface area, and pore size distribution
- •
Meso-pores in graphene and SWCNT electrodes exhibit better capacitive stability with high-frequency operations and a large variation of resistance at −30 °C to 60 °C
- •
AC electrode with mainly micro-pores shows an increasing resistance with high frequencies and less dependency on operating temperatures
