An urchin-like Co-doped NiS₂/C nanorod array with enriched sulfur vacancies for asymmetric supercapacitors

Abstract

The electrochemical activity and stability of transition metal sulfides are severely restricted by their poor conductivity and charging-discharge deformation. In this work, trimesic acid (H3BTC) was used as an organic...

Development of plasma technology for the preparation and modification of energy storage materials

“…Extensive research has demonstrated the enhanced intrinsic properties of energy storage materials through the introduction of heteroatom doping or functional group modification. This is commonly achieved through various methodologies, including high temperature sintering, 1,2 co-precipitation, 3,4 hydrothermal reactions, 5–7 vapor deposition (CVD/PVD), 8,9 chemical reactions, and other similar approaches. These techniques lead to improvements in specific capacity, initial efficiency, and rate capability of energy storage materials by inducing the formation of defects, vacancies, active sites, 10 etc.…”

A V–Ni-based nitride heterostructure as a highly efficient electrode for flexible all-solid-state supercapacitors

“…With the rapid improvement of the quality of human life, the development of flexible and wearable electronic devices has become extremely urgent. 1,2 Supercapacitors (SCs) have been regarded as one of the most desirable energy storage systems for next-generation electronics and electric vehicles owing to their rapid charge/discharge rate, excellent energy density, long cycling stability, high power density, low cost and environmental benignancy. [3][4][5][6][7] Especially, flexible all-solid-state SCs exhibiting outstanding mechanical properties and simplified configuration are becoming a research emphasis.…”
