Extended Data Fig. 7: Protective effect of C-LiXZM.

From: A highly stable and flexible zeolite electrolyte solid-state Li–air battery

Extended Data Fig. 7

Time-resolved optical images of lithium metal inserted in the test devices sealed with Celgard separator (immersed with organic electrolyte), glass fibre separator (immersed with organic electrolyte), LiXZM and C-LiXZM. The lithium metal sealed with LiXZM and C-LiXZM retains its metallic lustre after 1,000 h of ageing, which demonstrates that lithium metal can be effectively protected from the erosion of air components by zeolite membranes. Notably, lithium metal sealed with C-LiXZM is brighter than that sealed with LiXZM, because the hydrophobic carbon cathode surface can further block H2O from the air.
