Synergistic Relationship

Different characterization techniques were used to analyse the chemically activated carbons in (i) one dimensional analysis including MIP and BET, (ii) two dimensions including SEM and TEM and (iii) three dimensional X-ray CT. This structure has been directly linked to the electrochemical performance of supercapacitors for the first time.

Supercapacitor Electrode Materials

ABSTRACT The binary metal oxides are increasingly used as supercapacitor electrode materials in energy storing devices. Particularly NiCo2O4 has shown promising electrocapacitive performance with high specific capacitance and energy density. The electrocapacitive performance of these oxides largely depends on their morphology and electrical properties governed by their energy band-gaps and defects. The morphological structure of NiCo2O4 can be altered via the synthesis route, while the energy band-gap could be altered by doping. Also, doping can enhance crystal stability and bring in grain refinement, which can further improve the much-needed surface area for high specific capacitance. Given the above, this study evaluates the electrochemical performance of Ca-doped Ni1-xCaxCo2O4 (0 ≤ x ≤ 0.8) compounds. This stipulates promising applications for electrodes in future supercapacitors.
