Provided is a hybrid solid electrolyte comprising: a hybrid film including (i) 60 to 100 parts by weight of an ion conductive ceramic and (ii) 1 to 40 parts by weight of a polymer; and a liquid electrolyte including (i) an ion compound selected from the group consisting of lithium ions and sodium ions and (ii) a solvent, wherein the hybrid film is impregnated with the liquid electrolyte.

Hybrid solid electrolyte for secondary battery and manufacturing method thereof

Disclosed is a method of manufacturing a porous ceramic body, which includes: (S1) mixing silica powders having a particle size of 0.045&#x2dc;0.5 mm, zircon flour and wax, thus preparing a ceramic mixture; (S2) placing the ceramic mixture into a mold, thus producing a green body; and (S3) sintering the green body at high temperature, thus obtaining a porous ceramic body, wherein the silica having a particle size of 0.1&#x2dc;0.5 mm is contained in an amount of 50&#x2dc;80 wt % based on the total weight of the porous ceramic body; and also which produces a bulk porous ceramic body having good strength and leaching properties with excellent dimensional stability and shape stability.
