Figure 1. (A) Battery with sandwich structure. Schematic overview of four different approaches to engineer the electrolyte layer-cathode interface: (B) mixing electrolyte and cathode grains; (C) integration of electrolyte and cathode materials; (D) modification of cathode structure; and (E) modification of electrolyte.
