阅读说明：本技术 一种电极结构体及其制备方法 (Electrode structure body and preparation method thereof ) 是由 李宝良 王海蓉 周政 何凤荣 左都新 杨远博 于 2020-02-28 设计创作，主要内容包括：本发明属于电极箔技术领域,公开一种电极结构体及其制备方法。所述电极结构体包括基材和烧结体,所述烧结体形成于所述基材的表面,且所述烧结体上设置有裂纹,所述裂纹在烧结体进行水合处理之后形成。所述制备方法得到的电极结构体,裂纹的连续性好,且适合工业化生产。具有裂纹的电极结构体一方面能够有效提高电极结构体的折曲强度,降低电极结构体卷绕过程中的应力,从而降低应用过程中的断裂风险；另一方面,在提高电极结构体的折曲强度的前提下,同时使电极结构体保持原有较高的静电容量,以及较低的漏电流值,未对电极结构体的性能造成负面影响。(The invention belongs to the technical field of electrode foils and discloses an electrode structure body and a preparation method thereof. The electrode structure includes a base material and a sintered body formed on a surface of the base material, and a crack is provided on the sintered body, the crack being formed after the sintered body is subjected to a hydration treatment. The electrode structure obtained by the preparation method has good crack continuity and is suitable for industrial production. The electrode structure body with cracks can effectively improve the bending strength of the electrode structure body and reduce the stress in the winding process of the electrode structure body, thereby reducing the fracture risk in the application process; on the other hand, on the premise of improving the bending strength of the electrode structure, the electrode structure keeps the original high electrostatic capacity and low leakage current value, and the performance of the electrode structure is not negatively influenced.)
