Nanofiber Production Equipment| Deep Eutectic Solvent Gel Electrolytes Reinforced withCellulose Nanofibers for High-Performance Flexible Solid-StateSupercapacitors 2025-06-03
With the rapid development of wearable electronic devices and smart flexible equipment, solid-state supercapacitors (SCs) that combine high energy density, excellent cycle stability, and fast charge/discharge capabilities have become a research hotspot in the field of energy storage. As one of the core functional components, the comprehensive performance of gel electrolytes directly determines the safety, stability, and application scope of devices. However, traditional hydrogel electrolytes still face numerous challenges such as poor conductivity, insufficient mechanical strength, easy drying and freezing, unstable interfaces, and lack of self-healing capabilities. Additionally, material sustainability has gradually become an important criterion that cannot be ignored. Therefore, how to construct a multifunctional gel electrolyte with high conductivity, flexibility, self-healing properties, and environmental friendliness has become a key issue in the material design of flexible energy
