Analysis of SEI film on graphitic anode material using NFIR and LIBS

Abstract

Investigated the composition of the SEI layer on graphite negative electrodes under different conditions. The aim is to reveal the effect of certain electrolyte additives and/or conditioning strategies, which may lead to improved performance of Li-ion battery cells. Investigated the composition of the SEI (surface composition and depth profiling, including 3D investigation) upon initial lithiation of the graphitic anode. Investigated the changes in the SEI (surface composition and depth profiling, including 3D investigation) on 1st delithiation of the graphitic anode. The following techniques were used: ex situ and in situ NFIR and LIBS techniques.
