Morphology evolution and electrochemical behavior of NixMn1-x(OH)2 mixed hydroxides as high-performance electrode for supercapacitor

Recent advances in Ni-materials/carbon nanocomposites for supercapacitor electrodes

“…The various supercapacitors based on the Ni materials//active carbon electrodes have been employed in electrochemical applications, and the novel results of the reported papers are tabulated in Table 4. 182–219 The utilization of active carbon in supercapacitors highlights its valuable role in improving energy storage capabilities and supporting advancements in various fields where efficient power delivery and rapid energy transfer are essential. Ni(OH) 2 /ZIF-67-derived CoS core/carbon cloth (Ni(OH) 2 /CoS/CC) was used in the supercapacitor of Ni(OH) 2 /CoS/CC (cathode)//AC (anode) that revealed a remarkable energy density as well as its excellent electro-catalytic activity towards methanol oxidation.…”

“…While the Ni 3 /4Mn1/4(OH) 2 //AC supercapacitors exhibited a high energy density of 40.7 W h kg −1 capacitance retention of 94.4% after 3000 cycles. 201 2D Ni–Co hydroxide/BO 2 ((Ni x Co y )(OH) 2 /Co(BO 2 ) 2 ) was prepared and the optimized electrode of (Ni 0.5 Co 0.5 )(OH) 2 /Co(BO 2 ) 2 delivered a remarkable specific capacitance of 2257 F g −1 . The (Ni0.5Co0.5)(OH) 2 /Co(BO 2 ) 2 //AC supercapacitors provided a high energy density and excellent cyclic stability.…”

Preparation of MoFs-Derived Cobalt Oxide/Carbon Nanotubes Composites for High-Performance Asymmetric Supercapacitor

“…According to the energy storage mechanisms, there are two types of supercapacitors: electrical double-layer capacitors (EDLCs) and pseudocapacitors. The core of supercapacitors is the electrode material, which directly dominates the performance of energy storage [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ].…”
