This technology relates to a method for manufacturing a lithium manganese oxide-carbon source cathode active material and the lithium manganese oxide-carbon source cathode active material manufactured thereby. Specifically, it is a manufacturing technology for lithium manganese oxide cathode active material with enhanced stability by introducing a carbon source.
Existing technologies needed to address the limitations of conventional lithium manganese oxide cathode active materials, which suffered from poor cyclability and capacity fade, by introducing polymeric carbon sources to improve conductivity and stability. To this end, the present technology proposes a manufacturing method comprising the steps of forming a mixture of lithium manganese oxide dispersed in a solvent, adding a carbon source to the mixture to form a solution, and heating the solution to form a lithium manganese oxide-carbon source cathode active material.
Accordingly, this technology can improve the stability and power output of lithium manganese oxide-carbon source cathode active materials by enhancing conductivity and cyclability through the use of polymeric carbon sources. It has valuable applications in the fields of secondary batteries, advanced materials, and chemistry.
