| 英文摘要 | Garnet based solid-state batteries have the advantages of wide electrochemical window and good chemical stability. However, at Li-garnet interface, the poor interfacial wettability due to Li2CO3 passivation usually causes large resistance and unstable contact. Here, a Li2CO3-affiliative mechanism is proposed for air-accessible interface engineering of garnet electrolyte via facile liquid metal (LM) painting. The natural LM oxide skin enables a superior wettability of LM interlayer towards ceramic electrolyte and Li anode. Therein the removal of Li2CO3 passivation network is not necessary, in view of its delamination and fragmentation by LM penetration. This dissipation effect allows the lithiated LM nanodomains to serve as alternative Li-ion flux carriers at Li-garnet interface. This mechanism leads to an interfacial resistance as small as 5 Omega cm(2) even after exposing garnet in air for several days. The ultrastable Li plating and stripping across LM painted garnet can last for 9930h with a small overpotential. At Li-garnet interface, the poor interfacial wettability due to Li2CO3 passivation causes large resistance and unstable contact. Here the authors propose a Li2CO3-affiliative mechanism for air-accessible interface engineering of garnet electrolyte with superior wettability via facile liquid metal painting. |
