Title: Materials Science Investigations to Advance Li-ion and Li Metal Batteries

Abstract: Materials scientists are making important contributions to research and development efforts focused on advancing electrochemical energy storage technology. Lithium-ion batteries have improved greatly in recent years, but there is continued motivation to increase the specific and volumetric energy density, reduce cost, provide for rapid recharge, and the ensure safety of current and next generation batteries. Solid-state batteries may be one technology leading beyond current Li-ion designs. Several examples from the ORNL team programs will be presented, illustrating where studies of mechanical properties, fracture, diffusion and creep, and physical vapor synthesis of battery materials has contributed to new materials and architectures for rechargeable batteries.
