Research Abstract

Interfacial reactions of lithium batteries have been determined by in situ X-ray surface scattering measurements using epitaxial thin-films electrodes. The atomic arrangements of electrode surfaces change on being soaked in the electrolyte, and are subsequently reconstructed when a voltage is applied in the first charge process. Mechanical and technical development of surface structures is of considerable importance for improving the power characteristics and cyclability of new-generation batteries.
