Flexible high Li+ conductive lithium garnet–based dry solid polymer electrolyte membrane with enhanced electrochemical performance for lithium metal batteries

Poor stability of liquid electrolytes against lithium metal anodes and potential high-voltage cathodes in secondary batteries leads to dendrite formation and thermal runaway. In search of alternative electrolytes, solid electrolytes are promising candidates due to higher electrochemical stability and better safety. However, the solid electrolytes have low room temperature Li+ conductivity and weak interface with Li-metal anode/cathode contact....
