Abstract

An electrode for a lithium secondary battery that includes: a metal current collector; and an active material layer that is formed on the metal current collector and comprises an electrode active material, a conductive material, and an oxide-based solid electrolyte having a lithium ion source, wherein the electrode active material and the oxide-based solid electrolyte are dispersed in the active material layer in the form of particles and have a particle size distribution of span: 1 or less. A lithium secondary battery includes the electrode as a positive electrode. A method for manufacturing the electrode for a lithium secondary battery includes: mixing and dispersing the oxide-based solid electrolyte and a solvent to prepare a solid electrolyte dispersion; mixing the solid electrolyte dispersion, the electrode active material, and the conductive material to prepare an electrode active material slurry; and applying the electrode active material slurry to an electrode current collector.
