Abstract
Provided is a composite electrode for a lithium secondary battery for improving output and a lithium secondary battery including the composite electrode, in which, in a composite electrode having two or more active materials mixed therein, an active material having a small particle size is included in the composite electrode by being coagulated and secondarily granulated so as to allow mixed active material particles to have a uniform size, and thus, electrical conductivity is improved to have high output characteristics.
