Figure 7. (A) Schematic diagram of a solid-state lithium-air battery using a lithium anode, a polymer electrolyte film, an inorganic solid electrolyte sheet and an air electrode composed of CNTs and solid electrolyte particles^[54]. Reproduced from Ref.^[54] with permission from John Wiley and Sons. (B) Schematic representation of the Li-O₂ battery based on a MWCNTs-LLZTO/ILE gel cathode and LLZTO@ILE quasi-solid-state electrolyte^[55]. Reproduced from Ref.^[55]] with permission from Elsevier. ILE: Ionic liquid-based electrolytes; LLZTO: Li6.40La3Zr1.40Ta0.60O12; LLZTO@ILE QSSE: the ILE was solidified on LLZTO nanoparticles to construct quasi-solidstate electrolyte (QSSE); LLZTO-MWCNTs/ILE GC: the electrolyte was gelated by multi-wall carbon nanotubes (MWCNTs) to construct the gel cathode (GC).
