Article Synopsis
- Solid-state polymer electrolytes (SPEs) show potential for zinc metal batteries but struggle with issues like low ionic conductivity and unstable interfaces.
- A new approach uses a missing-linker metallic organic framework (MOF) to enhance the performance of a copolymer electrolyte made from PEGDA and PAM, improving zinc ion conduction and electrode contact.
- The resulting solid-state electrolyte achieves high ionic conductivity, excellent cycling stability, and low capacity degradation, making it promising for future zinc metal battery designs.
Poly(ethylene oxide) (PEO)-based electrolytes are often used for Li conduction as they can dissociate the Li salts efficiently. However, high entanglement of the chains and lack of pathways for rapid ion diffusion limit their applications in advanced batteries. Recent developments in ionic covalent organic frameworks (iCOFs) showed that their highly ordered structures provide efficient pathways for Li transport, solving the limitations of traditional PEO-based electrolytes.
