Abstract

We report on the optimized fabrication and electrochemical properties of ternary metal oxide (Ti-Mo-Ni-O) nanoparticles as electrochemical supercapacitor electrode materials. The structural, morphological, and elemental composition of the fabricated Ti-Mo-Ni-O...

Binder-free Mn–V–Sn oxyhydroxide decorated with metallic Sn as an earth-abundant supercapattery electrode for intensified energy storage

“…4a. 16 The high resolution Mn 2p spectrum showed two main peaks at 654.6 and 642.5 eV referring to Mn 2p 3/2 and Mn 2p 1/2 , respectively. [60][61][62] Upon Gaussian tting, the overlapped Mn 2p 3/2 peak is deconvoluted into three peaks at 642, 643.8, and 647.2 eV as shown in Fig.…”

“…As a result, developing supercapacitors with high energy density while maintaining their power density and cycling stability has become a critical challenge. [15][16][17] Transition metals are potential low-cost and environmentally friendly materials for energy storage and conversion technologies, due to their higher cycle stability compared to conductive polymers (CPs), which suffer from polymeric chain swelling and shrinking. [18][19][20] Additionally, transition metals are known for their higher specic capacitance compared to carbon-based materials.…”

Impact of oxygen‐defects induced electrochemical properties of three‐dimensional flower‐like CoMoO 4 nanoarchitecture for supercapacitor applications

“…[9][10][11] Considering various electrode materials into account, especially, transition metal oxides (TMOs) have been greatly accepted as favourable candidate for SCs owing to their relatively cost-effective, high-theoretical capacitance, and excellent electrochemical properties. [12][13][14][15] Besides, TMOs involve Faradic redox kinetics rather than the pure electrostatic charge storage behaviour, which thus not only dramatically mounts the capacitance but also the energy density of the SCs. [16][17][18][19] In particular, the binary cobalt molybdate (CoMoO 4 ) has received tremendous attention in recent years as a perspective batterytype electrode material because of its many impressive advantages, including fast and reversible redox kinetics, high capacity, multivalence distributions, and non-toxicity.…”
