Abstract：

Covalent　organic　frameworks　(COFs)　are　an　emerging　class　for　solid-state　electrolytes　due　to　their　ordered　and　customizable　ion　transport　nanochannels.　Although　high　ionic　conductivity　(σLi+)　and　Li+　transference　number　(tLi+)　are　achieved,　the　high-areal-capacity　solid-state　lithium　metal　battery　(LMB)　still　encountered　challenges,　which　is　mainly　determined　by　homogeneous　Li+　flux　through　channels　and　interfaces.　Herein,　we　design　a　COF　coupling　anionic　skeletons　with　branched　ion-conductive　chains　(COF-S)　as　tailored　fast　ion-transport　channels　to　achieve　high-areal-capacity　solid-state　LMB.　Then　the　dispersed　COF-S-based　electrolyte　is　further　obtained　by　incorporating　ethoxylated　trimethylolpropane　triacrylate　(ETPTA)　and　LiFSI　(ETPTA-COF-S)　via　in　situ　light　solidification.　In　this　way,　the　abundant　SO3−　groups　promote　Li+　adsorption　and　facilitate　axial　transport　via　1D　channels,　thus　enabling　high　σLi+　of　1.29　mS　cm−1　and　tLi+　of　0.83.　The　branched　chains　can　tailor　ion　channels　to　suppress　large-size　anions　transport,　disperse　and　uniform　Li+　flux,　thus　leading　to　high　average　Coulombic　efficiency　(CE)　up　to　98.43　%　for　100　cycles　(∼800　h)　at　0.5　mA　cm−2　under　the　high　areal　capacity　of　2　mAh　cm−2.　When　paired　with　2　mAh　cm−2　LiFePO4　(LFP)　cathode　and　thin　Li　anode　of　20　µm　Li∥ETPTA-COF-S∥LFP　exhibits　superior　cyclic　stability　for　80　cycles.　©　Science　China　Press　2024.
