Abstract
A method of manufacturing an electrode for a lithium secondary battery in which a thin film of active material is deposited on a current collector is provided that eliminates adverse effects on the battery caused by protrusions adhered on an electrode surface. The method of manufacturing an electrode for lithium secondary batteries includes depositing a thin film of active material on a current collector using thin-film deposition equipment as shown in FIG. 1, and performing a compression process after depositing the thin film, whereby the heights of protrusions formed on the electrode surface are reduced.
