| titleOfInvention | Electrode active material composition of lithium secondary battery and lithium secondary battery prepared using the same |
| abstract | The present invention provides an electrode active material composition for a lithium secondary battery and a lithium secondary battery prepared using the same. The lithium secondary battery includes a cathode and an anode including an electrode active material, a conductive agent, and a binder, a separator inserted between the cathode and the anode, and an organic electrolyte including a lithium salt and an organic solvent. The conductive agent includes carbon powder and graphite powder in a ratio of 3: 1 to 1: 3, and the binder includes a binder resin, which is a first binder, and a second binder that is partially dissolved and gelled in an organic solvent of an electrolyte solution. , The mixing weight ratio of the first binder and the second binder is 1: 3 to 3: 1. In the present invention, it is possible to increase the energy density of the electrode plate by using a mixture of carbon powder and graphite powder having a higher conductivity and smaller specific surface area as the conductive agent. In addition, as the binder in the electrode active material composition, the binder resin and the binder which is partially dissolved and gelled in the organic solvent of the electrolyte solution may be used together to increase the electrolyte-moisture capability of the electrode. As a result, the ion conductivity characteristics of the electrode are improved, thereby improving the charge and discharge characteristics and the life characteristics of the battery. |
