Research Abstract

Interfacial reactions of lithium batteries have been determined by in situ X-ray surface scattering measurements using epitaxial thin-films electrodes. The interracial structures determine the power density and the stability of lithium-excess layered material electrodes. Surface modification by Li3 PO4 solid electrolyte improved the stability of the electrode structure upon battery operations. Mechanical and technical development of surface structures is of considerable importance for improving the power characteristics and cyclability of new-generation batteries.
