A key problem for their use is the high interfacial resistance that develops between the two, increasing the total cell impedance. Here we show that the application of a thin conformal SiO2 coating onto a LICGC followed by silanization with (CH3CH2O)3–Si–(OCH2CH2)–OCH3 in the presence of LiTFSI results in good adhesion between the SiO2 and the LICGC, a low resistance interface, and good wetting of Li0. Further, the cross-linked polymer formed on the surface of the silanated SiO2 interface formed from excess (CH3CH2O)3–Si–(OCH2CH2)–OCH3 prevents corrosion of the LICGC by Li0 metal. The use of SiO2 as a “glue” enables compatibilization of inorganic ceramics with other polymers and introduction of interfacial pendant anions. %I ACS Publications
