Abstract:
A current collector for an electrochemical device and a method for manufacturing the same are provided. The current collector has wrinkles formed spontaneously according to heat expansion and cold shrinking of a metal thin film. A method for manufacturing an electrode includes heating a metal thin film for a current collector, stretching the heated metal thin film, and cooling the heated metal thin film.
