Special Issue Information

Dear Colleagues,

Polymer-based electrode materials have garnered significant attention in the field of energy storage systems due to their versatile properties and potential for addressing the limitations of conventional electrode materials. This Special Issue encapsulates the current progress of polymer-based electrodes, encompassing their design, synthetic methods, and applications in various energy storage devices, such as batteries and supercapacitors. The aim of this Special Issue is to report and explore the diverse range of polymers employed in electrode fabrication, highlighting their unique characteristics, structural designs, and electrochemical performance. Additionally, this Special Issue also aims to delineate the critical factors influencing the performance of polymer-based electrodes, including conductivity, stability, and flexibility, as well as strategies for enhancing electrochemical performance through novel polymer composite structures, morphologies, and functionalization techniques. This Special Issue underscores the challenges and future perspectives in the development of polymer-based electrode materials, emphasizing the need for continued research to advance their performance, scalability, and commercial viability in next-generation energy storage technologies. Original research articles and review papers related to polymer-based electrodes are welcome in this Special Issue.

Abstract
Si anode materials are promising candidates for next-generation Li-ion batteries (LIBs) because of their high capacities. However, expansion and low conductivity result in rapid performance degradation. Herein, we present a facile one-pot method for pyrolyzing polystyrene sulfonate (PSS) polymers at low temperatures (≤400 [...] Read more.
Si anode materials are promising candidates for next-generation Li-ion batteries (LIBs) because of their high capacities. However, expansion and low conductivity result in rapid performance degradation. Herein, we present a facile one-pot method for pyrolyzing polystyrene sulfonate (PSS) polymers at low temperatures (≤400 °C) to form a thin carbonaceous layer on the silicon surface. Specifically, micron silicon (mSi) was transformed into porous mSi (por-mSi) by a metal-assisted chemical etching method, and a phenyl-based thin film derived from the thermolysis of PSS formed a strong Si–C/Si–O–C covalent bonding with the Si surface, which helped maintain stable cycle performance by improving the interfacial properties of mSi. Additionally, PSS-grafted por-mSi (por-mSi@PSS) anode was coated with polyaniline (PANI) for endowing additional electrical conductivity. The por-mSi@PSS/PANI anode demonstrated a high reversible capacity of ~1500 mAh g−1 at 0.1 A g−1 after 100 cycles, outperforming or matching the performance reported in recent studies. A thin double layer composed of phenyl moieties and a conductive PANI coating improved the stability of Si-based anodes and provided an effective pathway for Li+ ion transport to the Si interface, suggesting that polymer-modified Si anodes hold significant promise for advanced LIB applications.

Due to the presence of the boronic acid moieties, poly-3-thienylboronic acid has an affinity for saccharides and other diol-containing compounds. Thin films of this novel chemosensitive polymer were synthesized electrochemically on the gold surface. The adhesion of the polymer was enhanced by the deposition of a monomolecular layer of thiophenol. The technology was used to fabricate conductometric sensors for glucose and other diol-containing compounds. Simultaneous two- and four-electrode conductivity measurements were performed. The chemical sensitivity to sorbitol, fructose, glucose, and ethylene glycol was studied at different pH and electrode potentials, and the corresponding binding constants were obtained. Depending on the electrode potential, the reciprocal values of the binding constants of glucose to poly-3-thienylboronic acid at neutral pH are in the range of 0.2 mM–1.0 mM. The affinity for glucose has been studied in buffer solutions and in solutions containing the major components of human blood. It was shown that the presence of human serum albumin increases the affinity of poly-3-thienylboronic acid for diol-containing compounds. Full article
