Power supply solution for formation of electronic aluminum foil at middle-high voltage and application method thereof

The invention relates to power supply solution for formation of electronic aluminum foil at middle-high voltage and application method thereof. The power supply solution comprises citric acid and salt thereof, and specifically comprises citric acid, ammonium citrate dibasic, ammonium dihydrogen citrate, ammonium citrate tribasic, potassium citrate, and sodium citrate, one or few of the above components is/are totally dissolved by pure water so as to prepare the power supply solution with conductivity of 20-80ms/cm and pH value of 5.0-7.5. The power supply solution for formation prepared by the method can lower the voltage of a power supply tank, lower energy consumption, effectively improve production efficiency, and improve product quality.
