Organic Matrix Stabilized Ultra‐Fine Bismuth Oxide Particles for Electrochemical Energy Storage Application

Abstract

The synthesis of an organic‐inorganic supramolecular hybrid system has been reported, using a wet‐chemical synthesis method, where the Bi2O3 nanoparticles are dispersed within the organic matrix. The XRD analysis showed the formation of crystalline Bi2O3. The XPS and Raman spectra analysis also confirmed the formation of Bi2O3. In this work, the organic molecule supported nanosized Bi2O3 has been used as an electrode material for supercapacitor application in presence of the aqueous solution of alkaline electrolyte (1.0 mol dm−3 of KOH) and exhibited a specific capacitance 407 F.g−1 along with the energy density value of 113 W.h.kg−1 at 1 A.g−1. The supramolecular system exhibited a long‐term stability by retaining 89% of the initial specific capacitance value after 500 cycles at the current density of 5 A.g−1.

Enhancement of dielectric and electric-field-induced polarization of bismuth fluoride nanoparticles within the layered structure of carbon nitride

“…The energy storage devices, those satisfy the requirement of higher capacity, faster recharge, environment friendly and lower cost, are in high demand. Several energy storage device concepts, such as, rechargeable batteries 1 , electrochemical supercapacitors 2 , 3 and advanced dielectric capacitors 4 have been recently developed. The dielectric materials with high energy density, minimum loss factor and wide range of temperature stability are the most favourite candidate for the energy storage capacitor application.…”

Organic–Inorganic Complexation Chemistry-Mediated Synthesis of Bismuth–Manganese Bimetallic Oxide for Energy Storage Application

“…In our previous communications, we have reported the role of bismuth-based oxide, sulfide, and fluoride as active electrode materials for electrochemical supercapacitor application. − In this report, a one-pot synthesis route for the preparation of organic molecule (hexamethylenediamine, HMDA)-stabilized bismuth–manganese bimetallic oxide nanoparticles has been described. In this synthesis method, HMDA played a dual role; initially, it was used as a complexation agent for bismuth­(III) and at the end of the synthesis, HMDA acted as a stabilizer for the bismuth–manganese bimetallic oxide nanoparticles.…”

Oxygen Vacancy-Enriched Bi2SeO5 Nanosheets with Dual Mechanism for Ammonium-Ion Batteries

“…As shown in Figure i, when the power density is 2985.07 W kg –1 , the energy density of the device can reach 207.13 Wh kg –1 , showing excellent power density and energy density. Compared with the previously reported Bi-based aqueous energy-storage devices, − our fabricated AIB showed excellent electrochemical performance.…”
