All-solid-state　lithium　metal　batteries(ASSLMBs)are　considered　as　one　of　the　ultimate　goals　for　the　development　of　energy　storage　systems　due　to　their　high　energy　density　and　high　safety.However,the　mismatching　of　interface　transport　kinetics　as　well　as　interfacial　instability　induces　the　growth　of　lithium　dendrite　and　thus,leads　to　severe　degradation　of　battery　electrochemical　performances.Herein,an　inte-grated　interface　configuration(IIC)consisting　of　in-situ　generated　Lil　interphase　and　Li-Ag　alloy　anode　is　proposed　through　in-situ　interface　chemistry.The　IIC　is　capable　of　not　only　regulating　charge　transport　kinetics　but　also　synchronously　stabilizing　the　lithium/electrolyte　interface,thereby　achieving　uniform　lithium　platting.Therefore,Li||Li　symmetric　cells　with　IIC　achieve　a　critical　current　density　of　up　to　1.6　mA　cm-2　and　achieve　stable　cycling　over　1600　hours　at　a　high　current　density　of　0.5　mA　cm-2.Moreover,a　high　discharge　capacity　of　140.1　mA　h　g-1　at　0.1　C　is　also　obtained　for　the　Li(Ni0.6Co0.2Mno.2)O2(NCM622)full　battery　with　a　capacity　retention　of　65.6％after　300　cycles.This　work　provides　an　effective　method　to　synergistically　regulate　the　interface　transport　kinetics　and　inhibit　lithium　dendrite　growth　for　high-performance　ASSLMBs.
