1. A method of making a solid garnet membrane, comprising:
pre-treating a solid garnet membrane comprising an air sensitive lithium-containing garnet with water by soaking the air sensitive lithium-containing garnet in water at a temperature in a range of 0° C. to 50° C. for a time in a range of 0.5 minutes to 60 minutes to form a uniform protonated garnet surface composition; and
contacting the uniform protonated garnet surface composition of the solid garnet membrane with an acid to form a porous uniform protonated garnet surface composition, wherein the acid is at a concentration in a range of 1M to 5M.
