Embodiment 1
[0034] (1) Pretreatment of nickel foam collector:
[0035] ① Cutting and pre-treatment of nickel foam:
[0036] First, cut the commercially available nickel foam into small pieces with a length and width of 2cm, then place the cut nickel foam in a beaker filled with 50mL of acetone, seal the mouth of the container with plastic wrap, and then place the beaker in ultrasonic cleaning Ultrasonic treatment is carried out in the ultrasonic cleaner, the power of the ultrasonic cleaner is 90W, and the ultrasonic treatment time is 30min, so as to degrease the nickel foam sheet at room temperature; after that, the nickel foam sheet that has been degreased with acetone under ultrasonication is taken out from the beaker , it was cleaned 5 times with deionized water, then the foamed nickel sheet that was treated with acetone and cleaned was placed in a beaker containing 50 mL of 2mol / L hydrochloric acid for etching, and the mouth of the container was sealed with a plastic wrap, and then P...

[0073] (1) Pretreatment of nickel foam collector:
[0074] ① Cutting and pre-treatment of nickel foam:
[0075] First, cut the commercially available nickel foam into small pieces with a length and width of 2cm, then place the cut nickel foam in a beaker filled with 50mL of acetone, seal the mouth of the container with plastic wrap, and then place the beaker in ultrasonic cleaning Ultrasonic treatment is carried out in the ultrasonic cleaner, the power of the ultrasonic cleaner is 90W, and the ultrasonic treatment time is 30min, so as to degrease the nickel foam sheet at room temperature; after that, the nickel foam sheet that has been degreased with acetone under ultrasonication is taken out from the beaker , it was cleaned 5 times with deionized water, then the foamed nickel sheet that was treated with acetone and cleaned was placed in a beaker containing 50 mL of 2mol / L hydrochloric acid for etching, and the mouth of the container was sealed with a plastic wrap, and then P...
