Abstract

The present application provides a manufacturing device and method for an electrode assembly. The manufacturing device for an electrode assembly comprises a winding pin and a heating component, wherein the winding pin is used for winding an electrode sheet and a separator to form a winding structure, and the heating component is configured to be inserted into the winding center of the winding structure and heat the winding structure. By means of the manufacturing device, the heating component can heat the winding structure at the winding center of the winding structure, such that at least some of ion channels in the separator in the inner ring of the winding structure are melt and close, thereby blocking ion shuttling, facilitating reduction of lithium deposition in the winding structure, and effectively lowering the risk of lithium deposition in a battery.
