Dual modulation of the morphology and electric conductivity of NiCoP on nickel foam by Fe doping as a superior stability electrode for high energy supercapacitors

Abstract

The dual advantages of stable morphology and enhanced electric conductivity of NiCoP by Fe doping endow the optimal Fe–NiCoP/NF-12.5% electrode with prominent cycling stability and rate performance.

Surface Structure Construction of Fibers in a Conductive Metal–Organic Framework/Metal/Cotton Electrode for Flexible Textile Supercapacitors

“…The major contribution to the total capacity comes from the surface diffusion-controlled process when the scan rate is less than 100 mV s –1 . However, the contribution from the surface capacitive-controlled process is the most when the scan rate exceeds 100 mV s –1 , which certifies the rapid electrochemical kinetics and superior rate capability of the CAPMOF electrode due to the fast charge adsorption/desorption procedures and redox reaction between the interface of the electrode/electrolyte at high scan rates. , …”

“…Furthermore, the total capacity can be quantitatively divided into two parts according to eq 10: 46,47…”

Fe and P dual-doped nickel carbonate hydroxide/carbon nanotube hybrid electrocatalysts for an efficient oxygen evolution reaction

“…The above results suggest that doping of Fe and P can effectively tune the crystallinity as well as morphology to afford more exposed active sites. 30–32…”

“…The above results suggest that doping of Fe and P can effectively tune the crystallinity as well as morphology to afford more exposed active sites. [30][31][32] The presence of chemical functional groups in the samples was investigated by FT-IR. For Fe-NiCHs/CNTs, the adsorption band ranging from 3112 to 3441 cm −2 can be attributed to the stretching vibration of the O-H bond of the metal-OH layer (Fig.…”

Defect engineering of electrode materials towards superior reaction kinetics for high-performance supercapacitors

“…12i). 183 In the low frequency region, Warburg coefficient (s) of the Fe-NiCoP/NF-x% were smaller than the pristine NiCoP, which veried the faster ion transport aer the Fe doping (Fig. 12j).…”
