Abstract
A method of preparing a slurry composition for a secondary battery positive electrode includes preparing a positive electrode active material pre-dispersion by mixing a lithium iron phosphate-based positive electrode active material, a dispersant, and a solvent, and preparing a slurry for a positive electrode by further mixing a conductive agent, a binder, and an additional solvent with the positive electrode active material pre-dispersion is provided. A positive electrode for a secondary battery which is prepared by using the same method, and a lithium secondary battery including the positive electrode are also provided.
