Background
Standard copper foils for electronic circuits are often switched to copper foil electrolyte systems for lithium ion batteries due to market conditions or specific production needs. The additive used in the former is mainly collagen or similar additive, and is influenced by the collagen or related additive in the process of switching the former to the latter, and the additive in the latter is difficult to establish a balanced system, and the waste copper foil needs to be continuously removed for more than half a month, so that the consumption of the collagen in the system and the influence on the lithium electrolytic copper foil at the later stage are accelerated, and waste in time and production cost is caused.
In general, in the process of switching a copper foil electrolyte system for an electronic circuit to a copper foil electrolyte system for a lithium ion battery, if no lithium-ion battery copper foil additive is added, most of additives such as collagen and the like remaining in a sewage tank of the former electrolyte system need to be consumed for a long time, and the remaining residual part also has adverse effects on the later lithium-ion battery copper foil, so that the copper foil surface is rough or has adverse effects such as color difference. When a normal additive of the copper foil for the lithium battery is added, because the additive contained in an electrolyte system of the copper foil for the lithium battery contains a displacement agent with a relatively strong displacement function, the displacement agent and chloride ions are combined in the electrolyte system to form a blocking layer, so that the consumption of collagen or similar additives is further prevented, and the time for switching the electrolyte system from an electronic circuit foil to the lithium battery foil is longer.
