Composition and growth behavior of the surface and electrolyte decomposition layer of/on a commercial lithium ion battery LixNi1/3Mn1/3Co1/3O2 cathode determined by sputter depth profile X-ray photoelectron spectroscopy.

ABSTRACT
A detailed X-ray photoelectron spectroscopy (XPS) study of the surface and electrolyte decomposition layer of a LixNi1/3Mn1/3Co1/3O2 (NMC) cathode from commercial NMC/graphite cells by intense sputter depth profiling (SDP) using a polyatomic ion gun is provided. Cathodes of a cell after electrochemical formation and a cell at a state of initial capacity (SOIC) of 80%, which was reached after 2500 full cycles at 30 °C, are investigated.
