Abstract In this paper, the boron (B) and nitrogen (N) are added into carbon (C) structure named BCN. The BCN was used as electrode materials in supercapacitor cell, which shows good performance electrochemistry test. research results show that of based-supercapacitor can be up to 806.1 mF at current density 3 mA KOH electrolyte. Besides, capacity cell DLC301 electrolyte 782.9 5 voltage increas...

Radiant energy (solar energy) plays a vital role due to its continuous power supply and environmentally friendly in meeting the people’s demand. The need for an endless of energy, majorly through solar exploitation has driven expansion diversification device proper storage. This review summarizes photo-supercapacitor’s working mechanism. classification supercapacitor was discussed advancements ...

Untreated coal char is explored as an ultra-low cost supercapacitor material in various electrolytes.

Cellulose fibers with porous structure and electrolyte absorption properties are considered to be a good potential substrate for the deposition of energy material for energy storage devices. Unlike traditional substrates, such as gold or stainless steel, paper prepared from cellulose fibers in this study not only functions as a substrate with large surface area but also acts as an interior elec...

Monodispersed hollow spindle-like nanosphere (HS-NS) and tetrapod nanorod (TP-NR) MnS nanocrystals are obtained via a facile template-free hydrothermal process. The MnS nanocrystals are used as supercapacitor materials and they exhibit high performances. The TP-NR nanocrystals show a higher specific capacitance of 704.5 F g(-1) compared to the HS-NS nanocrystals, and both show higher values com...

A new class of singular fractional linear systems and electrical circuits is introduced. Using the Caputo definition of the fractional derivative, the Weierstrass regular pencil decomposition and the Laplace transformation, the solution to the state equation of singular fractional linear systems is derived. It is shown that every electrical circuit is a singular fractional system if it contains...

Currently and also in future, the flexible wearable strain sensor would be high demand due to its direct applications biomedical health monitoring other engineering applications. The challenge is make function continuously with no additional wired powered supply system. In line this, there has been considerable research works towards integration of supercapacitor into sensors, them self-powered...
