Synthesis of mesoporous NiO nanoflake array and its enhanced electrochemical performance for supercapacitor application

Size-dependent capacitance of NiO nanoparticles synthesized from Ni-based coordination polymer precursors with different crystallinity

“…The specific capacitance for NiO-19 nm was determined to be 165, 154, 150, 145, and 134 F g À1 at scan rates of 10, 20, 30, 50 and 100 mV s À1 , respectively. Although there are some reports on different materials showing much higher specific capacitances [29][30][31], it still can compare with other recent reports on NiO architectures [8,13,32,33]. CV currents are directly proportional to the scan rates of CV, which demonstrates that, an ideal capacitive behaviour.…”

Facile hydrothermal synthesis of NiTe and its application as positive electrode material for asymmetric supercapacitor

“…Transition metal oxides/sulfides/selenides (e.g. NiO [21,22], MnO 2 [23,24], CoS [25], Co 0.85 Se [11]) have been extensively studied because of their excellent pseudocapacitive properties and considered as the promising positive electrode for supercapacitors.…”

Facile synthesis and characterization of high-performance NiMoO4 · xH2O nanorods electrode material for supercapacitors

“…The electrode materials for a pseudocapacitor include transition metal oxides, nitrides, sulfides, conducting polymers, et al They possess multivalent oxidation states/structures, so that they are capable for rich redox reactions [7][8][9][10][11]. The most remarkable among them are RuO 2 , which can achieve a specific capacitance as high as 1340 F g −1.…”
