Abstract | The garnet electrolyte presents poor wettability with Li metal, resulting in an extremely large interfacial impedance and drastic growth of Li dendrites. Herein, a novel ultra-stable conductive composite interface (CCI) consisting of LiSn alloy and LiN is constructed in situ between LiLaZrTaO (LLZTO) pellet and Li metal by a conversion reaction of SnNx with Li metal at 300°C. The LiSn alloy as a continuous and robust bridge between LLZTO and Li metal can effectively reduce the LLZTO/Li interfacial resistance from 4468.0 Ω to 164.8 Ω. Meanwhile, the LiN as a fast Li-ion channel can efficiently transfer Li ions and give their uniform distribution at the LLZTO/Li interface. Therefore, the Li/LLZTO@CCI/ Li symmetric battery stably cycles for 1200 h without short circuit, and the all-solid-state high-voltage Li/LLZTO@CCI/ LiNiCoMnO battery achieves a specific capacity of 161.4 mAhg at 0.25 C with a capacity retention rate of 92.6% and coulombic efficiency of 100.0% after 200 cycles at 25°C. |
