Embodiment 1
[0021] Weigh 12.48mL of water into a 50mL small beaker, and weigh 1.8791g of fumed silica into the small beaker to make a fumed silica hydrosol (ultrasound if necessary). Dilute 98% concentrated sulfuric acid with deionized water into an aqueous solution of sulfuric acid with a specific gravity of 1.37, let it stand to cool to room temperature and perform freezing treatment. Add 20mL of sulfuric acid aqueous solution with a specific gravity of 1.37 into the fumed silica hydrosol and mix thoroughly. Weigh polyvinylpyrrolidone accounting for 0.04% of the total mass of the gel battery electrolyte, add it to the above mixed solution, stir and mix thoroughly, and make the gel battery electrolyte.
Embodiment 2
[0023] Weigh 12.48mL of water into a 50mL small beaker, and weigh 1.8791g of fumed silica into the small beaker to make a fumed silica hydrosol (ultrasound if necessary). Dilute 98% concentrated sulfuric acid with deionized water into an aqueous solution of sulfuric acid with a specific gravity of 1.37, let it stand to cool to room temperature and perform freezing treatment. Add 20mL of sulfuric acid aqueous solution with a specific gravity of 1.37 into the fumed silica hydrosol and mix thoroughly. Weigh polyvinylpyrrolidone accounting for 0.08% of the total mass of the gel battery electrolyte, add it to the above mixed solution, stir and mix thoroughly, and make the gel battery electrolyte.
Embodiment 3
[0025] Weigh 12.48ml of water into a 50ml small beaker, and weigh 1.8791g of fumed silica into the small beaker to make a fumed silica hydrosol (ultrasound if necessary). Dilute 98% concentrated sulfuric acid with deionized water into an aqueous solution of sulfuric acid with a specific gravity of 1.37, let it stand to cool to room temperature and perform freezing treatment. Add 20ml of sulfuric acid aqueous solution with a specific gravity of 1.37 into the fumed silica hydrosol and mix thoroughly. Weigh polyvinylpyrrolidone accounting for 0.12% of the total mass of the electrolyte of the colloidal battery, add it to the above mixed solution, stir and mix thoroughly to prepare the electrolyte of the colloidal battery.
