Abstract: An electrode structure and preparation methods thereof, the electrode structure includes a substrate and a sintered body, wherein the sintered body is formed on the surface of the substrate, and the sintered body is provided with cracks that are formed after the hydration treatment of the sintered body. The continuity of cracks of the electrode structure was good, and the preparation method is suitable for industrial production. The electrode structure with cracks can effectively increase the bending strength and reduce the stress during the winding process of the electrode structure, thereby reducing the risk of fracture during the application process. It can also improve the flexural strength of the electrode structure while maintaining the original high electrostatic capacity and lower leakage current value of the electrode structure, without negatively affecting the performance of the electrode structure.
