| description | The invention discloses a production technology of a double-layer composite electrolytic copper foil. A specific technical process comprises the following steps of adding pure copper sheets and waterinto a dissolution groove; meanwhile, adding concentrated sulfuric acid into the dissolution groove; inflating air into the dissolution groove; filtering a prepared copper sulfate solution, and then adding into an electrolysis groove; meanwhile, adding an additive into the electrolysis groove; under the effect of an electric field, preparing a primary copper foil; cleaning a surface oxide layer ofthe primary copper foil in an acid washing groove; then, respectively coating the surface of the copper foil with an anti-oxidization layer and a reduction layer; next, performing cutting and packaging on the prepared copper foil to obtain a copper foil finished product. The copper foil has the advantages that in a later period of production, the surface of the copper foil is coated with the anti-oxidization layer at firs |
