| 中文摘要 | A lithium conductive Li(3)N film is successfully prepared on Li metal surface by the direct reaction between Li and N(2) gas at room temperature. X-ray diffraction (XRD), Auger electron spectroscopy (AES), cyclic voltammetry (CV), scanning electron microscopy (SEM), AC impedance, cathodic polarization and galvanostatic charge/discharge cycling tests are applied to characterize the film. The experimental results show that the Li(3)N protective film is tight and dense with high stability in the electrolyte. Its thickness is more than 159.4 nm and much bigger than that of a native SEI film formed on the lithium surface as received. An exchange current as low as 3.244 x 10(-7) A demonstrates the formation of a complete SEI film at the electroclelelectrolyte interface with Li(3)N modification. The SEI film is very effective in preventing the corrosion of the Li electrode in liquid electrolyte, leading to a decreased Li vertical bar electrolyte interface resistance and an average short distance of 3.16 x 10(-3) cm for Li ion diffusion from electrolyte to Li surface. The Li cycling efficiency depends on N(2) exposing time and is obviously enhanced by the Li(3)N (1 h) modification. After cycling, a dense and homogeneous Li layer deposits on the Li(3)N (1 h) modified Li surface, instead of a loose and inhomogeneous layer on the Li surface as received. |
