The binder includes a particulate conductive material, a fibrous conductive material, and a plate-like conductive material. The binder has a weight average molecular weight of 500,000 g / mol to 900,000 g / mol, bookbinder; And an amorphous binder having a weight average molecular weight of 200,000 g / mol to 400,000 g / mol, thereby having a pore structure and an electrically conductive network which are developed by a conductive material uniformly dispersed throughout the positive electrode mixture, And a secondary battery including the positive electrode mixture. |
