Title: SECONDARY BATTERY ELECTRODE, METHOD FOR MANUFACTURING SAME, SECONDARY BATTERY, AND METHOD FOR MANUFACTURING SAME
Abstract:
Provided is a method for manufacturing a secondary battery electrode, said method enabling stable and high-speed manufacturing of a secondary battery electrode having a straight clean cut part. A method for manufacturing a secondary battery electrode (10) according to one embodiment of the present invention comprises a first step for forming an active material layer (22) on at least one surface of a long core body (21). The method for manufacturing the secondary battery electrode (10) according to the one embodiment of the present invention further comprises a second step for cutting an electrode precursor (20) which is the long core body (21) having the active material layer (22) formed thereon, into a prescribed shape by using a continuous oscillation laser.
