Special Issue Information
Dear Colleagues,
With the rapid development of advanced electrochemical fields such as new energy vehicles, energy storage systems, flexible and wearable electronic devices, and emerging ion batteries, there is an increasingly urgent demand for electrolyte systems that can simultaneously deliver high ionic conductivity, efficient ion transport, high safety, high stability, device compatibility, and scalability for large-scale manufacturing. Polymer-based composite electrolytes have emerged as a prominent research hotspot in solid-state batteries and flexible energy storage owing to their high safety, mechanical flexibility, and highly tunable electrochemical performance. However, their large-scale practical application is still restricted by critical challenges, including sluggish room temperature ionic conductivity, poor electrolyte–electrode interfacial compatibility, and insufficient mechanical stability under dynamic conditions. Overcoming these bottlenecks requires a profound understanding of molecular-level ion transport mechanisms and the precise regulation of complex interfacial interactions at heterogeneous solid–solid boundaries.
This Special Issue focuses on the latest advances and future directions in polymer-based composite electrolytes, and aims to highlight representative achievements in improving ionic conductivity, ion transport efficiency, safety, stability, interfacial adaptability, and device performance. We cordially invite researchers to contribute original research articles, reviews, and communications. Contributions addressing the design of highly safe and stable composite electrolytes, dynamic interfacial regulation and stabilization mechanisms, ion transport regulation in multi-scale structures, performance retention under complex operating conditions, and innovative studies linking material construction, mechanistic analysis, and practical device validation are particularly encouraged. By bridging fundamental molecular chemistry with macroscopic energy storage performance, to illuminate pathways that promote both technological breakthroughs and industrial applications. Potential topics include, but are not limited to, the following:
- Design and synthesis of novel polymer-based composite electrolytes;
- Development of advanced organic, inorganic, and supramolecular fillers;
- Multiphase structural design and structure–property relationships;
- Fundamental mechanism analysis of ion transport and dynamics;
- Optimization and molecular engineering of electrolyte–electrode interfaces;
- Advanced characterization, theoretical simulations, and practical device applications.
