Process for Preparation of Cathode and Secondary Battery Comprising the Same

摘要

PURPOSE: A manufacturing method of a positive electrode is provided to provide a positive electrode which has excellent dispersity of a conducting agent and electric conductivity and is to be able to improve a rate performance and cycle performance of a battery. CONSTITUTION: A positive electrode for a secondary battery is manufactured by spreading a positive electrode mixture which comprises a positive electrode active material and a binder. The manufacturing method of a positive electrode comprises: a step of manufacturing a carbon solution by dispersing a conducing agent into an organic solvent; a step of manufacturing the positive electrode mixture by mixing the positive electrode active material and binder solution into the carbon solution; and a step of spreading the positive electrode mixture on a current collector and drying the positive electrode mixture spread on the current collector to remove the organic solvent.
