Customer ServiceLithium-ion battery electrodes contain a substantial amount of electrochemically inactive materials, including binders, conductive agents, and current collectors. These extra components significantly dilute the specific capacity of whole electrodes and thus have led to efforts to utilize foils, for example, Al, as the sole anode material.
The proposed surface architecture and working mechanism of lithium supplement could effectively eliminate the remaining challenges of high-capacity Al anodes, promoting the possibility of using commercial aluminum foils as single-material anodes for high energy density lithium-ion batteries.
Compared with the surface morphology of the lithium metallic electrode which is lithiated to 3 mAh (Fig. 1 c, d), it is notable that there is no dendrite formation during the lithiation of Al electrodes which means that the Al electrode possesses higher safety performance.
