Conjugated Polyelectrolytes: Underexplored Materials for Pseudocapacitive Energy Storage

Glenn Quek et al.

Summary: Conjugated polyelectrolytes (CPEs), characterized by electronically delocalized backbones with ionic functionalities, are suitable for energy-storing pseudocapacitor devices. This perspective discusses the basis for evaluating pseudocapacitor figures of merit, the general utility and challenges of neutral conjugated polymers, and recent advances in the use of CPEs in pseudocapacitor devices.

Pseudocapacitive Conjugated Polyelectrolyte/2D Electrolyte Hydrogels with Enhanced Physico-Electrochemical Properties

Glenn Quek et al.

Summary: This study demonstrates the use of 2D electrolytes as additives to enhance the pseudocapacitive performance of conducting polymer hydrogels (CPHs). The results show that the addition of 2D electrolytes improves cycling stability, specific capacitance, and working voltage window, with positively charged electrolytes being more effective than negatively charged ones.

Ionic Tunability of Conjugated Polyelectrolyte Solutions

Scott P. O. Danielsen et al.

Summary: In this study, the mesoscale morphology and physical properties of a high-mobility conjugated polyelectrolyte were manipulated by the addition of salt, variation of the charge-compensating counterion, and complexation with an oppositely charged polyelectrolyte. Added ions screened electrostatic repulsions, resulting in dissolution of ionic cross-links and hydrophobic collapse. Exchanging the counterion enabled finer control of solution behavior and modulation of self-doping behavior. Furthermore, novel CPE-CPE complexes with dense solutions and gels of semiconductive material were produced.

Increasing the molecular weight of conjugated polyelectrolytes improves the electrochemical stability of their pseudocapacitor gels

Ricardo Javier Vazquez et al.

Summary: Conjugated polyelectrolyte (CPE) hydrogels have shown promising applications as pseudocapacitors due to their high ionic conductivity and strong electrochemical performance. In this study, the molecular weight of a self-doped CPE, CPE-K, was systematically increased to enhance the cycling stability of the resulting hydrogel. The high molecular weight hydrogels exhibited improved mechanical strength, specific capacitance, and cycling stability, as well as wider working pseudocapacitive window, lower internal resistance, and higher ionic conductivity within the 3D conductive network. These results highlight the potential of CPE-K hydrogels for long-term pseudocapacitive technologies.

A Living Biotic-Abiotic Composite that can Switch Function Between Current Generation and Electrochemical Energy Storage

Yude Su et al.

Summary: In this study, a biotic-abiotic composite consisting of self-doped conjugated polyelectrolyte and electrogenic bacteria is demonstrated to reversibly switch between electrical current generation and electrochemical energy storage by the simple addition and removal of Mg2+ in the bulk electrolyte. This switch in functionality is achieved through reversible changes in the composite's macrostructures and the number of living bacteria within it, showing the possibility of on-demand switching between current generation and charge storage with one integrated living material.
