說明書
In addition, in the case of the conventional slurry-based technique, supply and management of various materials such as an active material, a conductive material, a binder, and a solvent should be performed, and the electrode is produced, based on a highly multi-step process such as slurry mixing, coating, drying, pressing, and slitting. In addition, in the case of the slurry production process, since the electrode active material slurry produced by gradually increasing the concentration (solid concentration) from a low concentration to a high concentration, it is difficult to manage the production process, for example, slurry concentration adjustment should be performed with difficulty considering characteristics of dispersion and precipitation reduction. In addition, in the case of a positive electrode, the production process is complicated and the process facility and management are difficult, for example, an organic solvent recovery device should be separately provided when producing the slurry.
However, since the method of producing an electrode according to the present invention is based on the active material bulk, rather than the slurry, the organic solvent recovery device (step) is unnecessary or may be minimized, the electrode may be produced by a significantly simplified process of production, slicing, and adhesion of the active material bulk, and costs of the process facility and management may be significantly decreased.
