摘要：
A flake-graphite painted layer (an electron/ion dual-conductive framework) was prepared by a spraying method and the resulting improved interface contact between a lithium-metal anode and garnet electrolyte was demonstrated. Experiments showed that a large decrease in the interface resistance, from 3062 to 40 Omega cm(2), was obtained. Besides a long cycling performance, the new interface also endured a tremendous Li volume change of 4.8 mu m cm(-2) in each stripping/plating step.
