Control method for improving copper powder particles in lithium battery copper foil dissolved copper deposition

The invention discloses a control method for improving copper powder particles in lithium battery copper foil dissolved copper deposition, and relates to the technical field of lithium battery copper foil production.The method comprises the following steps that firstly, copper is dissolved through a copper dissolving system, a solution is obtained, and the solution enters a filtering system through a collecting tank; 2, acquiring a pressure maintaining value of a filter in the filtering system in real time, and judging whether the proportion and the content of a medium in the filter need to be adjusted or not based on a comparison result of the pressure maintaining value and a threshold value of the pressure maintaining value; 3, the solution enters an electrolysis system through the filtering system, and the electrolysis system conducts electrolysis treatment on the solution; and 4, obtaining a dissolution and filtration evaluation value in real time, obtaining a dissolution and filtration grade based on the
