Abstract

Raman spectra of thin films of LiCo_xMn_2-xO ₄ (0<x<1) were recorded in a mixture of ethylene carbonate and dimethyl carbonate (1:1 by volume) containing 1 M LiBF₄ at electrode potentials of 3.5-5.5 V. The thin film electrodes were fabricated on gold substrates by electrostatic spray deposition (ESD). The in situ Raman spectra exhibited changes correlatable with the crystallographic structure and oxidation state of manganese and cobalt. The spectral changes were reversible by changing the electrode potential, indicating that lithium ion extraction and insertion proceeds in a reversible manner.
