Title: Probing battery chemistry with liquid cell electron energy loss spectroscopy

Abstract

Electron energy loss spectroscopy (EELS) was used to determine the chemistry and oxidation state of LiMn 2O 4 and Li 4Ti 5O 12 thin film battery electrodes in liquid cells for in situ scanning/transmission electron microscopy (S/TEM). Using the L2,3 white line intensity ratio method we determine the oxidation state of Mn and Ti in a liquid electrolyte solvent and discuss experimental parameters that influence measurement sensitivity.
