AI Technical Summary
Existing polyvinyl chloride solid electrolytes suffer from limited lithium-ion transport efficiency and poor interfacial compatibility with inorganic fillers and electrode materials, leading to issues with battery cycle stability and safety.
By silanizing CePO4, a PCL-based composite containing dynamic coordination bonds was prepared. This composite was then combined with polyvinyl chloride matrix through multi-component synergistic compounding. A stepwise crosslinking process involving humidity-induced silane hydrolysis condensation and UV curing was employed to construct a dual network structure of covalent crosslinking and dynamic coordination.
It achieves simultaneous optimization of electrolyte mechanical properties, ion conduction efficiency and electrochemical stability, improves battery cycle stability and safety, and is suitable for high-performance energy storage devices.
