| titleOfInvention | Electrode plate for lithium ion battery and manufacturing method thereof |
| abstract | The present invention discloses an electrode plate for a lithium ion battery and a method of manufacturing the same. The electrode plate comprises a current collector and an active material layer formed on the current collector, the active material layer includes an electrode active material, a polyimide resin as a first binder and a rubber-based material as a second binder, The concentration of the polyimide-based resin, which is the first binder, is gradually decreased or the concentration is uniformly distributed from one surface of the active material layer to the other surface that is not in contact with the current collector. Characterized in that the concentration of the rubber-based material of the second binder gradually decreases from the contacted surface to the other surface not contacted. The electrode plate of this invention improves not only the flexibility of an electrode plate but the binding force between an electrical power collector and an active material layer, and the binding force between an active material by controlling the density | concentration gradient of polyimide resin and rubber resin in an active material layer suitably. In addition, the binder of the present invention improves the stability of the battery because the de-HF reaction does not occur. In addition, since the binder content is reduced compared to the conventional case, it is possible to increase the content of the electrode active material, thereby improving the capacity characteristics of the battery. |
