Abstract

An electrodeposited copper foil and a preparation method thereof and a lithium battery are provided. The electrodeposited copper foil contains copper having a content of greater than or equal to 99.9 wt% and a chlorine element having a content of 100-200 µg/g, and further contains a gold element having a content of 80-200 µg/g and a platinum element having a content of 80-200 µg/g. The electrodeposited copper foil containing the gold element and the platinum element can remedy stripe breakage occurring in the rolling process of a lithium-ion battery and potential safety hazards during the use of the battery, thereby improving the elongation and the production process efficiency; in addition, minor addition of gold and platinum exhibits good electrical conductivity, thereby improving the electrical conductivity of the foil material.
