Abstract

A spirally-wound battery structure and a method for producing the same is provided. In the method, a power-supplying electrode plate spirally winds a hollow cylinder and has first conductive tabs and second conductive tabs. A first conductive terminal plate and a second conductive terminal plate are inserted into the hollow cylinder. Conductive welding sheets sleeve the conductive terminal plates to clamp the conductive tabs between the conductive welding sheet and the conductive terminal plate. The conductive welding sheet, the conductive tabs, and the conductive terminal plate are welded with laser. A casing encapsulates the hollow cylinder, the power-supplying electrode plate, the first conductive tabs, the second conductive tabs, the first conductive welding sheet, and the second conductive welding sheet. The first conductive terminal plate and the second conductive terminal plate penetrate through the casing.

Abstract

The present invention discloses a coating layer removing apparatus and a method for the same. The apparatus of the present invention comprises a transport device displacing an electrode plate; a laser device having a laser head arranged above the displacement path of the electrode plate; and a control center electrically connected to the transport device and the laser device. The method of the present invention comprises mounting an electrode plate on the transport device; using the control center to set the speed of displacing the electrode plate, and program the time interval, count and penetration depths of the laser beams; and using the device of the present invention to form exposed areas equidistantly on the electrode plate. The apparatus of the present invention automatically removes a coating layer with a laser beam without directly contacting the electrode plate. Therefore, the present invention can fast form exposed areas of high quality.
