Carbon nanotubes are excellent additives for the preparation of CNFs with improved microstructures and electrochemical capacitance.
The nucleating effect on graphitization at a low temperature, the excellent electrical conductivity and chemical stability make carbon nanotubes ideal additives for modulating the microstructure and improving the capacitance of electrode materials, as has been demonstrated by other groups, but never before for cellulose precursors.
Rufford, T. E., Hulicova-Jurcakova, D., Khosla, K., Zhu, Z. & Lu, G. Q. Microstructure and electrochemical double-layer capacitance of carbon electrodes prepared by zinc chloride activation of sugar cane bagasse.
Onions were formed by vacuum annealing of 5 nm nanodiamond (ND) powder at 1200 2000 °C with the goal to investigate the effect of carbon microstructure on specific capacitance and ion transport.
Healthy skin tissue has both electrical resistance and capacitance properties.
Actuation area and capacitance area are separated.
Fig. 6 GCD tests and capacitance retention.
Canalisation and capacitance are caused by epistatic interactions.
However, no correlation between vasoconstriction and capacitance response was found in DW, indicating the presence of other plausible mechanisms for the reduced capacitance response.
The unique microstructure and nitrogen functionalities enable the carbon to exhibit a capacitance of 245 F g−1 in a 6 mol L−1 KOH aqueous electrolytes, which is attributed to the contributions of double layer capacitance and pseudo-capacitance, with an excellent rate capability (188 F g−1 remained at 20 A g−1) and cycle durability.
