| 摘要 |
The present invention relates to an electrode active material slurry, to a manufacturing method thereof and to a lithium secondary battery comprising the same, wherein the electrode active material slurry comprises a first binding agent; a first conductive material; a second conductive material; and an electrode active material, and wherein the weight average molecular weight (Mw) of the electrode active material ranges from 27,000 to 380,000. The electrode active material according to an embodiment of the present invention comprises a binding agent having a molecular weight in a predetermined range and different kinds of conductive materials, thereby minimizing the coagulation of the conductive materials and improving the resistance characteristics of an electrode. The method for manufacturing an electrode active material slurry according to an embodiment of the present invention can significantly improve the nonuniform mixture degree of the electrode active material and the conductive materials by pre-dispersing the binding agent, which has been formed as uniform powder by being micronized mechanically, and the first conductive material, adding the second conductive material and thereby improving the uniform dispersion of the conductive materials. |
