Super-capacitors
EDLC(electrochemical double layer capacitors)
→ store E using ion adsorption
Pseudo-capacitors
→ fast surface redox reactions
→ higher capacitance than EDLC
Redox super-capacitors
electron transfer caused by electrochemical oxidation and reduction of active reagents
between two electrodes with different potentials
charge transfer properties
investigating transition metal oxides
specific morphologies
nanostructured materials
→ the charge storage from faradaic processes occurring at the surface of the material
→ the pseudo-capacitive effect, becomes increasingly important
mesostructured materials
→ enhanced oxidation and reduction kinetics
→ the relatively short diffusion path length for ions and electrons
