| 摘要 |
The present invention provides a cathode mixture for a secondary battery that includes carbon-based materials having diameters different from each other and a silicone (Si) based material having the diameter, which is 5-60% of the diameters of the carbon-based materials. In claim 1, the diameter of the carbon-based substance is 10-20 μm. According to the present invention, the cathode mixture for a secondary battery and a cathode include excellent capacity characteristics of the silicone-based material and can have high electrical conductivity at the same time. |
