Temperature-induced structural and chemical changes of ultrathin ethylene carbonate films on Cu(111)†
Abstract
The interaction of the Li-ion battery solvent ethylene carbonate (EC) with Cu(111) was investigated by scanning tunnelling microscopy (STM) and variable temperature X-ray photoelectron spectroscopy (XPS) under ultrahigh vacuum (UHV) conditions. Between 80 and 420 K, the decomposition of EC occurs along with distinct structural and chemical changes of the adlayer.
