Revealing SEI Formation and Evolution at the Li Anode/Liquid Electrolyte Interface in Li-ion Batteries by in situ Fourier Transform Infrared Spectroscopy
A novel in-situ FTIR method is developed to probe the Li anode/liquid electrolyte interface. Three different conventional electrolyte systems were tested: 1.2 M LiPF₆ in EC, 1.0 M LiPF₆ in EMC, and LP57 (1.0 M LiPF₆ in EC:EMC (3/7 vol %)). Using the spectroelectrochemical cell, FTIR measurements for...
