One-pot synthesis of nickel-cobalt hydroxyfluorides nanowires with ultrahigh energy density for an asymmetric supercapacitor

Porous spherical NiO@NiMoO4@PPy nanoarchitectures as advanced electrochemical pseudocapacitor materials

“…Recently, supercapacitors (SCs) have been regarded as one of hopeful energy storage devices due to the wonderful merits beyond the Li-ion batteries (LIBs), such as super cycle performance, ultrafast charging-discharging and high power density [1][2][3][4][5][6][7][8][9][10]. Compared with transitional electrochemical double layer capacitors (EDLCs) based on carbon-based materials, the pseudocapacitors show larger specific capacitance and bigger energy density.…”

Controllable vacancy strategy mediated by organic ligands of nickel fluoride alkoxides for high-performance aqueous energy storage

“…Obviously, the F–Ni–O 2 –R 2 electrode illustrated the lowest R s (0.65 Ω) and R ct (0.47 Ω) values, favorable for rapid charge transfer. 52 Finally, the cycling stabilities of the candidate electrodes were tested at a current density of 10 A g −1 (Fig. 3f).…”

Research progress on hydroxide fluoride-based electrode materials for supercapacitors

“…Zhang et al [51] utilized a one-pot solvothermal synthesis approach to create a novel and distinct nickel-cobalt hydroxide fluoride (NiCo-HF) nanowire material. The research explored the impact of varying hydrothermal temperatures on the formation mechanism.…”

“…Therefore, strategies such as doping and compositing have been employed to improve the performance of hydroxide fluorides. Although there have been reports on the use of hydroxide fluorides in energy storage applications such as lithium batteries [45][46][47][48] and supercapacitors [49][50][51][52] , the current performance is not sufficient to support large-scale energy storage applications. There is a wide variety of hydroxide fluorides, and common metal cations found in hydroxide fluorides include Mg, Co, Ni, Cu, Zn, and Cd, among others [53][54][55][56] .…”
