A FTIR and Raman study of spontaneous reactions occurring at the LiNi_yCo(1-y)O_2 electrodeon-aqueous electrolyte interface

摘要

Spontaneous reactions occurring at the surface of LiNi_yCo_(1-y)O_2-based electrodes during contact with non-aqueous organic electrolytes have been investigated by FTIR and Raman spectroscopy. It is found that several types of compounds and/or functional groups are formed on the electrode surface and that these compounds appear to be dependent on the type of electrolyte used.
