In this study, we developed a transparent two-electrode cell to carry out an in situ observation of the Li dendrite growth on Cu surface. Galvanostatic plating and stripping cycle(s) are applied at same current density on each cell. Meanwhile, the Raman spectroscopy is employed to take a mapping image along with the grown lithium surface. The morphology evolution of the Li dendrite growth and nucleation mechanism is observed in different electrolytes and additives. The behavior of lithium dendrite and SEI were analyzed comparatively with 1M LiPF6 EC/ DEC (v: v=1:1), 1M LiTFSI, DME/DOL (v : v=1:1), and 1M LiClO4, PC electrolyte at the same current density. We have clearly observed that after a few cycles of platting and stripping lithium dendrite grew dramatically on Cu surface with carbonate electrolyte and the Cu surface still remained some lithium dendrite due to the dead lithium formation, which causes low Coulombic efficiency. In addition, Raman spectroscopy is used to probe SEI composition. The correlation of lithium growth and its surface composition are established in this work, which can help to further understand the mechanism of lithium growth.
