Abstract：

Lithium　(Li)　metal　batteries　with　high　energy　density　are　of　great　promise　for　next-generation　energy　storage;　however,　they　suffer　from　severe　Li　dendritic　growth　and　an　unstable　solid　electrolyte　interphase.　In　this　study,　a　mixed　ionic　and　electronic　conductive　(MIEC)　interphase　layer　with　an　adjustable　ratio　assembled　by　ZnO　and　Zn　nanoparticles　is　developed.　During　the　initial　cycle,　the　in　situ　formed　Li2O　with　high　ionic　conductivity　and　a　lithiophilic　LiZn　alloy　with　high　electronic　conductivity　enable　fast　Li+　transportation　in　the　interlayer　and　charge　transfer　at　the　ion/electron　conductive　junction,　respectively.　The　optimized　interface　kinetics　is　achieved　by　balancing　the　ion　migration　and　charge　transfer　in　the　MIEC　Li2O-LiZn　interphase.　As　a　result,　the　symmetric　cell　with　MIEC　interphase　delivers　superior　cycling　stability　of　over　1200　h.　Also,　Li||Zn-ZnO@PP||LFP　(LFP　=　LiFePO4)　full　cells　exhibit　long　cyclic　life　for　2000　cycles　with　a　very　high　capacity　retention　of　91.5%　at　a　high　rate　of　5　C　and　stable　cycling　for　350　cycles　at　a　high　LFP　loading　mass　of　13.27　mg　cm-2.　©　2022　American　Chemical　Society.
