To achieve high performance Li metal batteries, Li+ transport and reductive electrolyte decomposition at Li metal electrode should be controlled. However, most of technologies have failed to concurrently handle them. In this presentation, we report a high-performance Li metal battery by exploiting the interface of ceramic and polymeric single ion conductor. In a hybrid single-ion conducting layer, space charge of Li+ induced by the hetero-junction of the two phases constitutes unique Li+ structure with high mobility along the interface, providing various principles to control Li plating/stripping and electrolyte decomposition. As a protective layer for Li metal electrode, it significantly enhances the reversibility of Li metal electrode and achieves compelling cycle life.
