Method for producing electrodeposited nickel starting sheet

The invention discloses a method for producing an electrodeposited nickel starting sheet. The method comprises the following steps: placing a starting sheet in dilute sulphuric acid for pickling treatment; the acid-washed starting sheet serves as an electrodeposition cell cathode, an electrodeposition cell anode is an insoluble anode, new electrodeposition liquid is introduced into an electrodeposition cell for circulation, the circulation amount of the new liquid is controlled, and the nickel starting sheet is produced according to different production periods; and then the nickel starting sheet is stripped from the starting sheet, the stripped nickel starting sheet enters a unit to be processed to obtain a nickel starting sheet product, and the stripped starting sheet is placed in dilute sulphuric acid again to be subjected to acid pickling treatment. The nickel starting sheet is obtained through the method of starting sheet acid pickling, nickel skin production and starting sheet stripping, the nickel star
