preparation example Construction

[0037] According to a non-limiting embodiment of the present invention, a method for preparing a zinc-air water-soaked battery is provided, which specifically includes the following steps.

[0038] Prepare zinc powder, carboxymethylcellulose and sodium hydroxide.

[0039] Sodium hydroxide is ground into powder, and zinc powder, carboxymethyl cellulose agent, and sodium hydroxide powder are mixed uniformly under airtight conditions at a ratio of 2:1:1 by mass parts and used as a negative electrode coating material for future use.

[0040] Lay a negative electrode coating material with uniform thickness as the first negative electrode layer, connect the current collector made of nickel foam to the wire and place it on the first negative electrode layer, and lay a negative electrode coating material with uniform thickness on the current collector as the second negative electrode layer , heat and press at about 55°C, set the holding time at 30 minutes, heat and press until the car...

Embodiment 1

[0050] Weigh 10g of zinc powder, 4g of sodium carboxymethylcellulose, and 4g of potassium hydroxide. Grind potassium hydroxide into powder. Fully stir the weighed material in a closed mixer to obtain a uniform powder after mixing; pour a certain amount of mixed powder into the mold, then put it into a current collector with a wire, and then place it on the current collector. Pour in a certain amount of mixed powder, heat press and hold the pressure for a certain period of time. The temperature of the hot press is set at 50°C, and the holding time is set at 20 minutes, so that the binder is solidified and formed, and the zinc negative electrode can be obtained. First cover the zinc negative electrode with absorbent paper, stack the positive electrode, negative electrode, and separator in turn, weld the negative electrode wire and positive electrode together, fix it with a heat shrinkable tube, and assemble it into the battery case to get the battery monomer. After completing ...

Embodiment 2

[0053] Weigh 10g of zinc powder, 5g of sodium carboxymethylcellulose, and 5g of potassium hydroxide. Grind potassium hydroxide into powder. Fully stir the weighed material in a closed stirrer to obtain a uniform powder after mixing. Pour a certain amount of mixed powder into the mold, then put a current collector with wires, and then pour a certain amount of mixed powder on the current collector, heat pressurize and hold the pressure for a certain period of time, the temperature of hot pressurization Set it to 60°C, set the holding time to 10 minutes, let the binder solidify and shape, and then the zinc negative electrode can be obtained. First cover the zinc negative electrode with absorbent paper, stack the positive electrode, negative electrode, and separator in turn, weld the negative electrode wire and positive electrode together, fix it with a heat shrinkable tube, and assemble it into the battery case to get the battery monomer. After completing the above steps, dip ...

Abstract

The invention discloses a zinc air battery capable of being used with water and a preparation method therefor. The zinc air battery capable of being used with water comprises a battery shell and at least one group of battery stacks; the battery shell comprises a base shell with an accommodating space in the interior and a shell cover for sealing the base shell; the at least one group of battery stacks are mounted in the accommodating space of the base shell; each group of the battery stacks comprises an isolation net, an air positive electrode and a zinc negative electrode which are stacked in sequence, wherein the zinc negative electrode is coated in a water-absorbing paper sleeve to be electrically insulated from the air positive electrode; and in addition, the coating layer material of the zinc negative electrode comprises 20-30% of strong alkali based on mass percentages. The zinc air battery is simple in preparation process and capable of being used with water, and meanwhile, the discharge consistency in battery use is improved.

Description

technical field [0001] The invention relates to the field of air batteries, in particular to a zinc-air battery and a preparation method thereof. Background technique [0002] With the increase of people's consumption and the acceleration of industrialization, the global demand for energy is increasing day by day, resulting in a large consumption of non-renewable energy, a sharp decrease in its reserves, and the problems of environmental pollution and energy shortage are becoming increasingly prominent. Research and development of cleaner and more efficient green energy has become an important means for various countries to solve energy, environmental, social and economic problems. Zinc-air batteries use oxygen in the air as the positive electrode electrochemically active material, and use metal zinc as the negative electrode electrochemically active material, which has the characteristics of high energy density, abundant resources, and green and pollution-free reactive mate...
