Abstract
Provided is a method for manufacturing a positive electrode for a secondary battery, the method including applying a first positive electrode slurry including a first positive electrode active material on a positive electrode current collector, forming a first positive electrode mixture layer by primarily rolling the current collector applied with the first positive electrode slurry, applying a second positive electrode slurry including a second positive electrode active material on the above-formed first positive electrode mixture layer, and forming a second positive electrode mixture layer on which the first positive electrode mixture layer is laminated by secondarily rolling the first positive electrode mixture layer applied with the second positive electrode slurry.
