Thin film technology is applied in different fields of Li-ion
battery research and development, such as the fabrication of thin
film cells and model electrodes. Data obtained by surface and
interface analysis of thin films provides important insights into
fundamental processes such as charge compensation mechanism or
interface formation. In this overview, we present the analysis of
LiCoO2 and LiPON thin films using photoemission. It
includes data obtained directly after preparation, after exposure to
molecular species and/or after electrode-electrolyte interface
formation. Information both on electronic structure and surface
chemistry of the films is deduced from core level spectra, valence
band spectra, Fermi level position and work function. Next to PES
analysis of our films, we address composition, structure and
functionality in more general terms in relation to literature.
Founded in 1887, the Zeitschrift für Physikalische Chemie covers the main developments in physical chemistry, placing with an emphasis on experimental research. It represents a combination ofdiscusses reaction kinetics and spectroscopy, surface research and electrochemistry, thermodynamics and the structure analysis of matter in its various conditions, among other topics.
