Garnet-type solid-state batteries(SSBs)are con-sidered to be one of the most promising candidates to realize next-generation lithium metal batteries with high energy density and safety.However,the dendrite-induced short-cir-cuit and the poor interfacial contact impeded the practical application.Herein,interface engineering to achieve low interfacial resistance without high temperature calcination was developed,which Li6.4La3Zr1.4Ta0.6O12(LLZTO)was simply coated with complex hydride(Li4(BH4)3I(3L1L))in various mass ratios n(Li4(BH4)3I)-(100-n)LLZTO(10 ≤ n≤ 40).The interfacial conductivity increases by more than three orders of magnitude from 8.29 × 10-6 S·cm-1 to 1.10 × 10-2 S.cm-1.Symmetric Li cells exhibit a high critical current density(CCD)of 4.0 mA·cm-2 and an excellent cycling stability for 200 h at 4.0 mA·cm-2.SSBs with polymeric sulfur-polyacrylonitrile(SPAN)cathode achieve a high discharge capacity of 1149 mAh·g-1 with a capacity retention of 91％after 100 cycles(0.2 C).This attempt guides a simple yet efficient strategy for obtaining a stable Li/LLZTO interface,which would promote the devel-opment of solid-state batteries.
