AI Technical Summary
Existing hot press needle beds can only be applied to the formation process of batteries of a selected thickness, which has poor versatility and leads to increased equipment and production costs.
A thermoforming needle bed was designed with an adjustable placement space along a preset extrusion direction. It is equipped with first and second pressure plates and an adjusting component, which can adjust the position of the pressure plates to accommodate batteries of different thicknesses, maintain the electrical connection between the probe and the electrode, and reduce electrode damage.
Stable electrical connection between probes and electrodes was achieved during the formation process of batteries of different thicknesses, reducing equipment and battery production costs.
