Ammonium adipate is mainly used as a formation agent in the manufacturing process of low-voltage aluminum foil and solid-state capacitors, and as a solute in medium- and low-voltage electrolytes. Its aqueous solution can also be used as a charging agent for medium- and high-voltage aluminum foil and in capacitor manufacturing. In the production of electronic aluminum foil, ammonium adipate is used as a working solution, and it has high requirements for chloride ion content, which must be controlled below 2 mg/kg.
