Laser cleaning device for electrode tab of battery and laser cleaning method using the same

Abstract

A laser cleaning device, and a laser cleaning method using the same, for removing an electrolyte solution stuck to an electrolyte tab during a process of injecting the electrolyte solution are disclosed. The laser cleaning device for an electrode tab of a battery includes: a cleaning housing, in which a battery case for receiving an electrode group, an electrolyte solution and an electrode tab exposed to the outside are embedded; a laser generator which includes a laser source for generating a laser beam and an output controller for controlling output of the laser beam; a laser transmitter which transmits the laser beam generated by the laser generator; and a laser emitting unit which is installed inside the cleaning housing, and which irradiates the laser beam transmitted by the laser transmitter onto the electrode tab so as to remove liquid pollutants stuck to the electrode tab. The laser cleaning method comprises steps generally corresponding to the latter functions of the laser cleaning device.
