Electrochemical supercapacitors of anodized-brass-templated NiO nanostrutured electrodes

Three-Dimensional Porous Ti3C2Tx-NiO Composite Electrodes with Enhanced Electrochemical Performance for Supercapacitors

“…According to the report that only electric double layer capacitance was recognized in the in neutral electrolytes [37], the excellent faraday capacity of NiO could be produced not only on the surface of the electrode but also in the whole electrode and it was better than the capacitance of Ti 3 C 2 T x itself; hence, higher capacitance and energy density could be obtained. When under the same electrode area, the pseudocapacitor can be 10–100 times the capacity of the double layer [30,38]. Moreover, we compared our results with major published data on porous 2D materials and have listed the major characteristics of each report, such as test configuration, specific capacitance, capacitance retention, and electrolyte in Table 2.…”

Template-assisted synthesis of NiCoO2 nanocages/reduced graphene oxide composites as high-performance electrodes for supercapacitors

“…Electrochemical impedance spectra (EIS) measurement is also a signicant aspect for quantitatively evaluating the electrical resistance of NiCoO 2 /rGO composites. 46,47 Fig. 6(a) demonstrates the Nyquist plots of the rGO, NiCoO 2 and NiCoO 2 / rGO electrodes to illustrate their impedance characteristics.…”

NiO Pseudocapacitance and Optical Properties: Does The Shape Win?

“…NiO synthetic pathways include sol-gel, hydrothermal, solvothermal redox [2,3], and microwave-assisted reactions [4], among others. They can be obtained in several shapes, arrangements, and super-structures [5][6][7][8][9][10][11]. Although NiO properties can be tuned by targeted synthesis [12], the tuning procedure of the synthetic parameters is very fine, and only a narrow range of combinations yields one morphology or a specific range of pores sizes [13][14][15][16].…”
