Description

TECHNICAL FIELD

[0001] The utility model relates to battery processing technical field especially relates to a solid state battery pole piece clamping material pushing device. BACKGROUND

[0002] The solid state battery pole piece is the core component of the battery, and its design directly affects the battery performance and safety. The surface of the new solid state battery pole piece is coated with a layer of functional gel material. This material plays multiple roles in battery assembly: on the one hand, it precisely bonds the positive and negative pole pieces through adhesion during lamination, ensuring structural stability; on the other hand, it forms a dense isolation layer after solidification, preventing positive and negative contact and avoiding short circuit risk. At the same time, the gel material also has ion conductivity, which can build a continuous ion transmission channel between the solid electrolyte and the electrode, reduce the interface impedance, and improve the battery rate performance. This design simplifies the assembly process and significantly improves the cycle life and safety of the battery, providing important technical support for the large-scale application of solid state batteries.

[0003] In the existing die-cutting machine, the pole piece material belt usually passes between the pressure roller and the traction roller, and is clamped and rolled by the pressure roller and the traction roller to convey the pole piece material belt to the clamping assembly. The clamping assembly first clamps and fixes the pole piece material belt, and then cuts the pole piece material belt into the required size by the cutting device, so as to facilitate subsequent lamination. However, since the surface of the solid state battery pole piece is coated with a layer of gel material, which has certain adhesion, the cut material piece is easily adhered between the two clamping plates of the clamping assembly, causing difficulty in material taking and affecting production efficiency.
