The invention discloses a manufacturing method of a high-tensile lithium battery copper foil. Copper is dissolved so that a main electrolyte can be prepared; the main electrolyte is subjected to multi-stage filtering and then mixed with an additive solution so that an electrolyte solution can be obtained; and electrolyzing is performed under the temperature of 30-70 DEG C and the electric currentdensity of 30-85 A/dm2 so that an original foil can be made. The lithium battery copper foil manufactured by the method is good in effects of the tensile strength and the ductility, and the color andthe brightness of the copper foil are stable and can be easily controlled. The tensile strength of the copper foil is obviously improved by using a thiourea compound as a C-type additive.
