Sodium-ion batteries (SIBs) are considered the next-generation candidates for partially substituting commercial lithium-ion in future energy storage systems because of abundant sodium/potassium reserves and these batteries’ cost-effectiveness high safety. Gel polymer electrolytes (GPEs) have become a popular research focus due to their advantages terms safety performance on quasi-solid-state sodium-ion (QSSIBs). Building previous studies that incorporated MOF fillers into polymer-based gel electrolytes, we propose 3D sandwich structure which materials first pressed thin films then coated protected by materials. Using this approach, achieved an ion conductivity 1.75 × 10−4 S cm−1 at room temperature transference number 0.69. Solid-state using film electrolyte exhibited long cycling stability 2 C current density, retaining 75.2% specific capacity after 500 cycles.
