Study on solid electrolyte interface film (SEI film) formed on noble electrode surface was carried out by Surface Enhance Raman Scattering (SERS) for the first time in the world. The high quality SERS spectra of the SEI film were also obtained. The new phenomena of Li_tuned light emission were discovered in Li_doped silicon materials. The adsorbed states of pyridine molecule on SnO anode materials were investigated, which could provide proof for comprehending the structure of the SEI film.
