PROCESS FOR PREPARING ELECTRODE OF LITHIUM SECONDARY BATTERY USING FIBER PULSE TYPE LASER

摘要

A manufacturing method of an electrode of a lithium secondary battery by using a fiber pulse type laser is provided to minimize burr and electrode dust generated in the cut surface in cutting and to obtain desired various sizes of electrodes by only one cutting process. A manufacturing method of an electrode of a lithium secondary battery comprises a process for cutting an electrode by irradiating a laser on the one side of electrode in cutting the electrode coated with a coating layer containing an active material to a metal foil with the predetermined size. The cutting process is carried out with a fiber pulse type laser.
