Atomic Force Microscopy Applications to the Next Generation Lithium-ion Batteries

Recently, demands for lithium-ion batteries (LIB) in various fields are increasing. In particular, understanding of the reaction mechanism occurring at the electrode-electrolyte surface/interface is significant for the development of advanced LIBs. Meanwhile, research and development of LIBs highly requires a new specific characterization approach. For example, atomic force microscopy (AFM) has been utilized to the LIB research field for various purposes such as investigation of topography, electrochemical reactions, ion transport phenomena, and measurement of surface potential at high resolution. Advances in the AFM analysis have made it possible to inspect various material properties such as surface friction and Young s modulus. Therefore, this technique is expected to be a powerful method in the LIB research field. Here, we review and discuss ways to apply AFM to LIB studies
