Summary: Fast charging is crucial for next-generation energy storage devices, but it brings increased security risks and capacity attenuation. To overcome these issues, researchers have developed a novel gel polymer electrolyte (GPE) based on polyvinylene carbonate, poly (ethylene oxide), poly (vinylidene fluoride-co-hexafluor-opropylene), and ionic liquid modified carbon nanotubes (IL-CNTs). This GPE exhibits improved lithium ion transportation, resulting in enhanced ionic conductivity and lithium-ion transference number. The GPE also demonstrates a wide electrochemical window and good cycle life, making it a valuable guideline for designing fast-charging GPEs.

Summary: This study explores the possibility of flexible supercapacitors using hydrogel electrolytes with immobilized pair ions. By one-pot copolymerization, five polymeric samples were obtained, with the content of HEMA increasing with each sample. The ionic conductivities of the hydrogel electrolytes were found to increase with the increasing presence of immobilized pair ions. Raman spectra analysis showed that hydrogel electrolytes with higher ionic conductivity had more free anions and fewer contact ion pairs. Dynamic mechanical analysis revealed that increasing the content of HEMA resulted in higher compressive strength. The HAS4 supercapacitor was found to meet the requirements, with an ionic conductivity of 64.8 mS cm-1, compressive strain of 65%, and compressive strength of 0.45 MPa. The HAS4 supercapacitor demonstrated 96.3% capacitance retention after 5000 charge/discharge cycles at 2 A g-1, and no significant loss in capacitance under different bending angles.
