        1. Solid electrolytes have attracted much attention due to their great prospects
          in a number of energy- and environment-related applications including fuel
          cells. Fast ion transport and superior mechanical properties of solid electrolytes
          are both of critical significance for these devices to operate with high
          efficiency and long-term stability. To address a common tradeoff relationship
          between ionic conductivity and mechanical properties, electrolyte membranes
          with proton-conducting 2D channels and nacre-inspired architecture
          are reported. An unprecedented combination of high proton conductivity
          (326 mS cm?1 at 80 °C) and superior mechanical properties (tensile strength
          of 250 MPa) are achieved due to the integration of exceptionally continuous
          2D channels and nacre-inspired brick-and-mortar architecture into one materials
          system. Moreover, the membrane exhibits higher power density than
          Nafion 212 membrane, but with a comparative weight of only ≈0.1, indicating
          potential savings in system weight and cost. Considering the extraordinary
          properties and independent tunability of ion conduction and mechanical
          properties, this bioinspired approach may pave the way for the design of nextgeneration
          high-performance solid electrolytes with nacre-like architecture.
