The effects of fluorinated metal–organic frameworks as additives in polymer-based electrolytes for all-solid-state lithium batteries

(Zr) were obtained by using a simple solution casting method. By introducing fluorinated groups, the interaction between the MOF and the polymer was significantly improved, which not only stabilizes the SEI layer but also improves the ionic conductivity of the SCEs, thus advancing the practical application of solid composite electrolytes in lithium metal batteries.
