ACTIVE MATERIAL FOR COMPOSITE ELECTRODE OF LITHIUM SECONDARY BATTERY FOR INCREASED OUTPUT, AND LITHIUM SECONDARY BATTERY INCLUDING SAME

摘要

The present invention relates to an active material for a composite electrode of a lithium secondary battery for increased output, and a lithium secondary battery including same. In the composite electrode in which at least two kinds of active materials are mixed, active materials having small sizes are agglutinated with each other to secondarily particlize the agglutinated active materials so that the mixed active particles have a uniform size, thereby containing the secondarily particlized active materials in the composite electrode. Therefore, the lithium secondary battery may have improved electrical conductivity and increased power characteristics.
