Background In the production process of the new energy automobile battery copper nickel-plated pole piece, the electrolysis step is a core link for determining the surface quality and performance of the pole piece, and a uniform and compact pretreatment layer is formed on the surface of the copper strip through electrolysis reaction, so that the binding force of a subsequent nickel-plated layer and the electrochemical performance of the pole piece are directly affected; In the long-term operation process of the existing electrolytic tank, impurities such as metal scraps, anode slime, unreacted electrolyte crystals and the like generated by electrolytic reaction are easy to gather at the bottom of the tank body. The accumulation of the impurities not only can change the local concentration and fluidity of the electrolyte, but also can be adsorbed to the surface of the copper strip in the electrolysis process, so that the defects such as spots, pinholes and the like of the pole piece can be caused. More importantly, the prior cleaning mode has the limitations that electrolyte in the tank needs to be discharged firstly during cleaning, so that not only is the electrolyte wasted, but also waste liquid needs to be additionally treated to avoid pollution; excessive cleaning time directly results in a forced extension of the cleaning cycle of the electrolytic cell, during which bottom impurities continue to accumulate, such that electrolyte composition uniformity gradually deteriorates.
