Nickel-based bimetallic battery-type materials for asymmetric supercapacitors

NiMn-Layered Double Hydroxide Porous Nanoarchitectures as a Bifunctional Material for Accelerated p-Nitrophenol Reduction and Freestanding Supercapacitor Electrodes

“…For supercapacitors, especially, the use of freestanding binder-free electrodes has attracted considerable attention of the researchers due to advantages in terms of their lightweight, low electrode resistance, and mechanical/chemical stability. Utilizing free-standing electrodes, the conductivity issue can be resolved to a larger extent in the case of supercapacitor applications. − NiMn LDH being a member of the LDH family also suffers from phase stabilization and conductivity issues. A correlating mechanism needs to be optimized, which can resolve both phase stabilization and conductivity issue simultaneously.…”

CuCoNi–S anchored CoMoO4/MoO3 forming core–shell structure for high-performance asymmetric supercapacitors

“…Supercapacitors, as promising energy storage devices, have been extensively studied due to their fast charge–discharge capability, higher power density and longer life cycles. 1–3 In recent years, various state of the art supercapacitors have been reported, for example with core–shell hybrids, 4 layered double hydroxides, 5 MXene nanosheets, 6 nanofluidic 7 and others 8–10 as the electrodes in assembled supercapacitors. However, the lower energy density of supercapacitors still restricts their applications.…”

NiCo2S4 Nanocone Arrays/Phosphorus‐Doped Hollow Carbon Nanospheres for High‐Performance Supercapacitors

“…Owing to the continuous consumption of chemical energy and the deterioration of the environment, it is an urgent need to design an energy storage device with excellent performance [1–4] . Supercapacitors (SC) have received extensive attention due to their ultra‐high‐power density and long cycle life [5–10] .…”

“…Owing to the continuous consumption of chemical energy and the deterioration of the environment, it is an urgent need to design an energy storage device with excellent performance. [1][2][3][4] Supercapacitors (SC) have received extensive attention due to their ultra-high-power density and long cycle life. [5][6][7][8][9][10] The electrochemical performance of supercapacitors is affected by the electrode material and electrode structure, but the electrochemical performance of a single electrode material is not well.…”
