Description

Technical Field

[0001] This utility model relates to the field of new energy battery electrode processing, specifically a simple press-fitting machine for new energy battery electrodes. Background Technology

[0002] With the rapid development of new energy technologies, new energy batteries are also undergoing continuous innovation. In new energy batteries, the electrode sheets establish electron transport channels through metal current collectors (aluminum foil / copper foil), while the active material layer and binder layer work together to maintain the mechanical strength of the electrode and prevent structural collapse during charging and discharging. The electrode sheets are composed of positive and negative conductive materials: the positive electrode uses lithium compounds such as lithium cobalt oxide, lithium iron phosphate, and ternary materials (such as lithium nickel cobalt manganese oxide), coated on the surface of aluminum foil; the negative electrode is mainly composed of graphite-based carbon materials, coated on copper foil, achieving stable lithium ion insertion and extraction through a layered structure. The electrode sheets are coated on the aluminum foil surface and are sheet-like. Due to production convenience, the initially produced electrode sheets are relatively large, while new energy batteries are small and vary in shape. Therefore, it is necessary to cut the large electrode sheets into smaller ones. However, the cut small electrode sheets are flat and cannot be directly used as battery electrodes. To address this, a simple press-fitting machine was designed to press the cut small battery electrode sheets into the desired shape for the battery. Utility Model Content
