ELECTRODE FOR USING IN A SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An electrode for a secondary battery is provided to minimize volume expansion and contraction of electrode active materials generated in the charge and discharge and to ensure excellent cycleability, mechanical stability, thermal stability and electrical reliability. CONSTITUTION: An electrode for a secondary battery comprises a thin film layer positioned on the substrate. The thin film layer comprises aggregates including electrode active material nanoparticles and carbon particles mixed with the electrode active material nanoparticles. A method for preparing the electrode for the secondary battery comprises the steps of: (S10) preparing a solution including electrode active material nanoparticles and carbon particles; (S20) applying electric field to the solution and spraying the charged particles to a substrate; and (S30) forming a thin film layer including the particles on the substrate.
