METHOD FOR MANUFACTURING NEGATIVE ELECTRODE FOR SECONDARY BATTERY AND NEGATIVE ELECTRODE FOR SECONDARY BATTERY

A method of manufacturing a negative electrode for a secondary battery includes a first step of preparing a lithium metal sheet coated with a lithium metal or to which the lithium metal is adhered in a form of a thin film on a release film and wound into a roll, a second step of laminating the lithium metal sheet to allow the lithium metal to be adjacent to a negative electrode material mixture, to thereby manufacture a negative electrode in which lithium metal is laminated and a third step of applying pressure to the negative electrode. The release film is coated with silicon. The negative electrode manufacturing method uniformly laminates or bonds lithium metal which is difficult to handle on the negative electrode material mixture of the secondary battery and advantageously enhances the speed of the pre-lithiation by using the patterned lithium metal.
