This type of die-cutting device has disadvantages such as easy breakage of the waste electrode strip, high waste output, and low precision. It can cause the equipment to malfunction and require manual redirection of the material. Moreover, the more waste there is, the higher the production cost. The low precision also affects the yield of the finished electrode sheets. [Utility Model Content]
