Description

Technical Field

[0001] The present invention relates to the field of battery production, and particularly to a pressure forming device for solid-state batteries. Background Art

[0002] With the rapid development of new energy technologies, solid-state batteries have gradually become an important development direction for the next generation of battery technologies due to their advantages such as high energy density, long cycle life, and high safety. In the manufacturing process of solid-state batteries, pressure forming is a crucial step, the purpose of which is to ensure full contact of the materials inside the battery by applying a certain pressure, thereby guaranteeing the performance and consistency of the battery. However, when dealing with different models of solid-state batteries, existing pressure forming devices often suffer from problems such as the inability to meet performance requirements in terms of pressure and pressure application cycle, uneven pressure distribution, and poor adaptability, resulting in substandard battery performance and even potential damage to the battery surface.

[0003] Existing pressure forming devices usually adopt a single pressure application method, making it difficult to adapt to solid-state batteries of different sizes and shapes. Especially when the length of the battery core changes, the device cannot flexibly adjust the distance between the conductive clamps, leading to uneven pressure distribution and affecting the forming effect of the battery. For example, in the Chinese utility model patent "Battery Forming Pressure Clamp" (Application No.: CN202020211679.X). In addition, traditional devices have insufficient pressure control accuracy in high-pressure environments (such as greater than 50 MPa), making it difficult to meet the forming requirements of special batteries, resulting in inconsistent performance of individual batteries in the battery pack and affecting the overall performance of the battery pack.

According to different battery models, conductive clips can be set on the profile plate 51 at the corresponding positions of the charging and discharging of the battery cells, or the corresponding distance can be adjusted according to the length of the battery cells, thereby adjusting the distance between the two conductive clips.
