Special Issue Information

Dear Colleagues,

In the last three decades, the development of polymer electrolytes has received great attention due to their potential applications in electrochemical power generation, storage and conversion systems. A polymer electrolyte is often a membrane composed by the dissolution of an ion-conducting salt in a polymer matrix with high molecular weight. Besides this, it can be based on ion-conducting polymers or ionomers containing charged functional groups (e.g. –SO3H, –PO3H2, –COOH), which typically have a multiphase structure containing both hydrophobic and hydrophilic regions. These solid systems possess ionic conduction properties and therefore are widely employed in electrochemical devices such as solid-state batteries, rechargeable batteries, fuel cells, electrolysers, supercapacitors, dye-sensitized solar cells, electrochemical sensors and electrochromic windows.

The technological advancement in the field of polymer electrolytes plays a pivotal role in the development of energy storage/conversion systems. This Special Issue is intended to cover the latest progress in polymer electrolytes for energy-related applications. In particular, this Special Issue aims to gain insights into the development of different types of polymer electrolytes, recent approaches, and their technological applications.

To obtain a proton exchange membrane (PEM) with high proton conductivity and low methanol permeability, a novel amino-sulfo-bifunctionalized GO (NSGO) was synthesized and explored as a filler for sulfonated poly(arylene ether nitrile) (SPEN). The result indicated that the microstructure of composite membranes was rearranged by NSGO and strong acid–base interactions were formed between fillers and the SPEN matrix, affording enhanced thermal, mechanical, and dimensional stabilities. Moreover, it was found that NSGO fillers were uniformly dispersed in the SPEN matrix, generating efficient proton-conducting paths along the SPEN/NSGO interface. Meanwhile, the sulfonic and amino groups of NSGO served as additional proton hopping sites to connect the ionic clusters in the SPEN matrix, creating interconnected and long-range ionic pathways. In such a way, proton-conducting highways with low energy barriers are constructed, which enhance the proton conductivity of the composite membranes via the Grotthuss mechanism. Furthermore, the composite membranes also effectively prevent methanol permeation, and therefore high selectivity (the ratio of proton conductivity and methanol permeability) is endowed. Compared to SPEN membrane, a 3.6-fold increase in selectivity is obtained for the optimal composite membrane. This study will provide a new strategy for the preparation of high-performance PEM.
