Conjugated Polyelectrolyte Thin Films for Pseudocapacitive Applications

Advanced Materials, 2023
AbstractA subclass of organic semiconductors known as conjugated polyelectrolytes (CPEs) is characterized by a conjugated backbone with ionic pendant groups. The water solubility of CPEs typically hinders applications of thin films in aqueous media. Herein, it is reported that films of an anionic CPE, namely CPE‐K, drop cast from water produces single ...

Pseudocapacitive Coating for Effective Capacitive Deionization

ACS Applied Materials & Interfaces, 2018
Capacitive deionization (CDI) features a low-cost and energy-efficient desalination approach based on electrosorption of saline ions. To enhance the salt electrosorption capacity of CDI electrodes, we coat ion-selective pseudocapacitive layers (MnO2 and Ag) onto porous carbon electrodes (activated carbon cloth) with only minimal use of a conductive ...

Water Desalination By Pseudocapacitive Deionization

ECS Meeting Abstracts, 2017
Capacitive deionization (CDI) is an electrochemical desalination process based on electrochemical principles that involves storing ions inside pores of capacitive, carbon-based electrodes. Although there have been intensive efforts for improving CDI performance, its broader application has been limited due to the low charge storage capacities of ...

Pseudocapacitive performance of NiCo2O4 nanostructures

AIP Conference Proceedings, 2019
NiCo2O4 (NCO) nanostructures were synthesized by a simple hydrothermal method using three different surfactants such as ethylene glycol (EG), oxalic acid (OA) and ammonium fluoride (NHF). Morphology of the different nanostructured materials has been recorded using SEM.

Amorphous Cobalt Hydroxide with Superior Pseudocapacitive Performance

ACS Applied Materials & Interfaces, 2014
Cobalt hydroxide (Co(OH)2) has received extensive attention for its exceptional splendid electrical properties as a promising supercapacitor electrode material. Co(OH)2 study so far prefers to crystal instead of amorphous, in spite of amorphous impressive electrochemical properties including the ability to improve the electrochemical efficiency based ...

Conducting Polymers for Pseudocapacitive Energy Storage

Chemistry of Materials, 2016
Developing energy storage devices to be utilized within a rapidly advancing energy market requires a multipronged approach whereby material synthesis and engineering fundamentals combine to enable technological advances. These devices should be able to store a large amount of energy in a small, lightweight package, and should be able to distribute that

Carbon electrodes with high pseudocapacitance for supercapacitors

Russian Journal of Electrochemistry, 2012
Electrochemical properties of electrodes on the basis of CH900-20 activated carbon (AC) cloth were studied in concentrated H2SO4 solutions in a wide range of potentials from −0.8 to +1 V RHE. Cyclic voltammetric curves measured in two ranges of potentials were analyzed: in the reversibility range (from 0.1 to 0.9 V) and in the deep cathodic charging ...

Pseudocapacitive Charge Storage in Thin Nanobelts

Advanced Fiber Materials, 2019
This article reports that extremely thin nanobelts (thickness ~ 10 nm) exhibit pseudocapacitive (PC) charge storage in the asymmetric supercapacitor (ASC) configuration, while show battery-type charge storage in their single electrodes. Two types of nanobelts, viz.

Capacitive versus Pseudocapacitive Storage in MXene

Advanced Functional Materials, 2020
AbstractMXene electrodes in electrochemical capacitors have a distinctive behavior that is both capacitive and pseudocapacitive depending on the electrolyte. In this work, to better understand their electrochemical mechanism, first‐principles calculations based on the density functional theory combined with the implicit solvation model are used (termed
