An electrolyzed copper foil and a current collector of an energy storage device are provided. The electrolyzed copper foil includes a transition layer and a nano-twin copper layer formed on the transition layer. The transition layer has an equiaxial grain of a (111) plane having a volume ratio of 20-40%, a (200) plane having a volume ratio of 20-40%, and a (220) plane having a volume ratio of 20-40%. A thickness of the transition layer is 0.2 &#x3bc;m to 1.5 &#x3bc;m. The nano-twin copper layer has a columnar grain of the (111) plane having a volume ratio of more than 85%, and a thickness of the nano-twin copper layer is 3 &#x3bc;m to 30 &#x3bc;m.
