Embodiment 1
[0025] Weigh 0.6 g of water-absorbing resin polyacrylic acid cross-linked polymer (such as Carbopol 740B resin, Noveon, INC) according to 3% of the total amount of water (20 g), and slowly sieve it into rapidly stirring water until Carbopol is completely swollen to form a hydrosol . Then slowly add 10g of polystyrene acrylic emulsion to the above gel, stir to form a white cream, after fully emulsified, add 3ml of acetone or ethanol to eliminate air bubbles, then quickly apply the cream to a film coating machine, dry, The result is a homogeneous polymer film that can be stored and transported like conventional separators. When the membrane is in use, immerse the membrane together with the positive and negative electrodes of the battery (such as nickel hydroxide positive electrode, hydrogen storage alloy negative electrode) in 5-10N potassium hydroxide solution for 5-20 hours, take out the trapped dry lye, and put it into vacuum drying Dry it in the box for 2 hours, and add 0.5...
Embodiment 2
[0028] Weigh cellulose and acrylic acid cross-linked polymer water-absorbent resin according to 5% of the total amount of 6N potassium hydroxide aqueous solution (20g), and slowly sieve it into the above-mentioned 6N potassium hydroxide aqueous solution which is stirred rapidly, until the polymer is completely swollen and forms a gel. glue. Then slowly add polystyrene acrylic emulsion of 30% gel weight to the above gel to emulsify to form a white cream. After fully emulsified, quickly apply the cream on glass or other substrates with a smooth surface, and dry it in vacuum for 2 hours. , In this way, the quasi-solid polymer aqueous solution system electrolyte membrane for alkaline batteries described in the present invention has been prepared.
Embodiment 3
[0030] Under ultrasonication, add 0.054g nano Y2O3 into 20g 6N potassium hydroxide aqueous solution, and continue ultrasonication for 15 minutes to fully disperse Y2O3. Weigh cross-linked polyacrylate water-absorbent resin and 1.0% PVA water-absorbent resin with lye content of 3.0%, and slowly sieve the above two water-absorbent resins into the above-mentioned 6N potassium hydroxide aqueous solution which is stirred rapidly, until the polymer is completely swollen and forms a gel glue. Then slowly add 30% polymethyl acrylate emulsion of the gel weight to the above gel to emulsify to form a white cream. After fully emulsifying, quickly apply the cream on a glass or other substrate with a smooth surface, and dry it in vacuum for 2 hours. In this way, the electrolyte membrane of the quasi-solid polymer aqueous solution system for the alkaline battery described in the present invention is prepared.
