CATHODE FOR SECONDARY BATTERY HAVING POROUS POSITIVE ACTIVE MATERIAL LAYER COMPRISING METAL OXIDE NANOPARTICLES AND THE FABRICATION METHOD THEREOF

摘要

PURPOSE: A positive electrode for a secondary battery and a manufacturing method thereof are provided to rapidly charge and discharge the electrode with a high current, and to secure an excellent electric contact structure. CONSTITUTION: A manufacturing method of a positive electrode for a secondary battery comprises the following steps: forming a composite fiber web mixed with a metal oxide precursor and a membranous polymer on a positive electrode current collector by spinning a solution including the precursor and the polymer; thermo-compressing the composite fiber web; and forming a porous positive electrode active material layer including metal oxide nano particles by removing the membranous polymer from the composite fiber web.
