| Abstract Scope |
Gallium-tin metal is a liquid metal at room temperature which makes it easily to be produced, and it also has relative stable charge-discharge performance which gallium-based electrodes have. In the experiment, we added tin into pure gallium liquid to make 92 wt.% gallium- 8 wt.% tin electrode. Compared to pure gallium electrode, gallium-tin electrode shows relative high capacity (120 mAh/g V.S. 75 mAh/g), without too much compromise in stability. XRD and SEM-EDS test prove that we succeed to produce Ga-Sn-Cu IMCs on the interface of electrode. Following CV test exhibits two charging peaks and two discharging peaks. It can explain that the increasing capacity is because new-adding tin provides more spaces for lithium ion insertion and extraction. We believe that gallium-tin will be a very promising lithium ion battery electrode material.
