Abstract:
1. A method of manufacturing an electrode for a lithium secondary battery, the method comprising: preparing a clay dispersion by dispersing clay having a layered structure with an interlayer distance of from about 1 to about 10 nm in a first solvent; preparing a composite by mixing the clay dispersion with a polymer or a polymer solution prepared by dissolving the polymer in a second solvent; wherein the composite comprises polymer intercalated between layers of the clay, preparing a composition for forming an electrode active material layer by adding an electrode active material to the composite and mixing the electrode active material and the composite; and coating and drying the composition on a current collector to form an electrode active material layer, wherein the polymer comprises at least one selected from the group consisting of polyvinylidene fluoride (PVDF), polyvinyl alcohol (PVA), and polyacrylic acid (PAA), wherein the clay dispersion is prepared at a temperature of about 40° C. to about 60° C.
