XPS analysis of solid-electrolyte interphase layer formed on a lithium-ion battery negative electrode
Submitted by Adam.Roberts on Tue, 05/10/2022 - 09:12This applications note demonstrates the use of both conventional (Al Kα) and higher photon energy (Ag Lα) excited X-ray Photoelectron Spectroscopy (XPS) to characterise the solid electrolyte interphase layer formed on a graphite anode during charge/discharge cycles. Samples were prepared in a glove box at the manufacturing site and transported to the XPS analysis laboratory using an air sensitive sample transport accessory.
