Abstract
Provided is a positive electrode material slurry for secondary battery including a positive electrode active material, a conductive agent, a binder, and a solvent, wherein the conductive agent includes a first conductive agent and a second conductive agent having different particle shapes and sizes. Since the conductive agent of the present invention may be uniformly dispersed in the positive electrode active material by including a point-type conductive agent, as the first conductive agent, and carbon nanotubes (CNTs) subjected to a grinding process as the linear second conductive agent, conductivity of an electrode to be prepared may be improved and a secondary battery having improved high-rate discharge capacity characteristics may be provided.
