    • PURPOSE: An electrode assembly is provided to easily ion-exchange between a positive electrode plate and a negative electrode plate by supplying enough electrolyte to a whole part of an electrode plate, thereby capable of improving a performance of a secondary battery. CONSTITUTION: An electrode assembly accepted in the battery case together with electrolyte comprises an electrode plate(110) in which an unevenness part is formed in order to flow the electrolyte from outside to inside on a surface coated with active material; and a separator inserted between the electrode plates. On both surfaces of the electrode plate, the unevenness part is formed. The unevenness part of the electrode plate is formed by rolling process. The rolling process is conducted by using one or more rollers with a protrusion.
    • 目的:提供一种电极组件,用于通过向电极板的整个部分供应足够的电解液,容易地在正极板和负极板之间进行离子交换,从而能够提高二次电池的性能。 构成:与电解质一起被接纳在电池壳体中的电极组件包括电极板(110),其中形成有不平坦部分,以便在涂覆有活性材料的表面上将电解质从外部流动到内部; 以及插入在电极板之间的隔板。 在电极板的两个表面上形成凹凸部。 电极板的不平坦部分通过轧制工艺形成。 轧制过程通过使用具有突起的一个或多个辊进行。
