Abstract: All solid state lithium-ion batteries have the advantages of high safety, long cycle life and high energy density, as compared with the conventional lithium-ion batteries, and have been attracting more and more research interest. Solid electrolyte is a crucial component of all solid state lithium-ion batteries, which largely determine the performance of the batteries. In this work, a polymer-lithium-ceramics complex was designed and synthesized. The structure and dynamics of the polymer-ceramic interface was studied with solid-state NMR techniques.

Key words: solid-state NMR, interface, structure and dynamics, solid electrolyte
