Rechargeable lithium metal batteries have been recognized one of the most promising energy storage devices due to their superior energy density. However, serious safety concern and poor cyclability are featured originating from uncontrolled lithium dendrite growth and unstable solid electrolyte interface (SEI) layer. One strategy to suppress dendrite growth is surface modification with Amphiphilic block copolymers, such as PDMS-b-PAA, which bear some clear advantages including absorbing mechanical stress, conducting lithium ion, controling the lithium dendrite growth process. With scattering techniques using neutrons and in situ scattering studies, the structures of the surface modified lithium metal anodes and structure formation processes can be studied. Moreover, by applying GISANS, the horizontal structures and vertical structures of the polymer films on the lithium metal surfaces can be investigated reflectivity.
