description The invention provides an activation method of an electrolytic water hydrogen production electrode, a preparation method of the activated electrolytic water hydrogen production electrode, the electrolytic water hydrogen production electrode and an electrochemical device. The activation method comprises the following steps: (1) constructing an electrolytic bath based on a first nickel-based electrode, a second nickel-based electrode and an alkaline electrolyte; and (2) positive electrolysis and reverse electrolysis are alternately carried out, so that the first nickel-based electrode and the second nickel-based electrode are activated, and the activated water electrolysis hydrogen production electrode is obtained. According to the method, forward electrolysis and reverse electrolysis are alternately carried out for multiple times, so that nickel on the surface of the nickel-based electrode for hydrogen production through water electrolysis is repeatedly reconstructed for multiple times to form the flower-shape
