Tetra germanium nonaselenide enwrapped with reduced graphene oxide and functionalized carbon nanotubes (Ge₄Se₉/RGO/FCNTs) hybrids for improved energy storage performances

Abstract

The development of multifunctional layered semiconductor materials and their carbonaceous hybrids as acceptable positive electrode materials for supercapacitor application is the key of interest. Ternary germanium selenide (Ge4Se9) with reduced...

Porous polyoxotungstate/MXene hybrid films allowing for visualization of the energy storage status in high-performance electrochromic supercapacitors

“…The charge transfer resistance ( R ct ) is the resistance generated at the interface between the active material-coated electrode and electrolyte. 64 The R ct values of the MXene/P 2 W 18 and NW@MXene/P 2 W 18 electrodes were 70.84 and 66.68 Ω, respectively. NW@MXene/P 2 W 18 has a lower R ct value, indicating that the charge transfer between the electrolyte ions and the electroactive substances is easier.…”

A SnO2/MXene hybrid nanocomposite as a negative electrode material for asymmetric supercapacitors

“…5(b) illustrates the relationship between the current and scan rate at a particular potential. The current and scan rates were related to each other by the power law mentioned below: 47 i = av b where a and b are adjustable parameters.…”

CNTs-Supercapacitors: A Review of Electrode Nanocomposites Based on CNTs, Graphene, Metals, and Polymers

“…The advancement of multifunctional materials and their carbonaceous hybrids as supercapacitor electrodes are of critical importance. Das et al [70] reported a supercapacitor based on the ternary germanium selenide (Ge 4 Se 9 ) with CNTs and reduced graphene oxide (RGO) and 1 M H 2 SO 4 as the electrolyte. They observed that the SC of the supercapacitor was 440 F/g with 98% coulombic efficiency after 5000 cycles.…”
