Embodiment 1

[0036] Embodiment 1 A kind of preparation method of Prussian blue type aluminum-air battery material

[0037] 1) Mix 0.1428g cobalt chloride hexahydrate, 0.2647g sodium citrate, and 20mL water in a 50mL beaker A, stir to dissolve.

[0038] 2) Mix 0.1317g of potassium ferricyanide and 20mL of water in a 50mL beaker B, and stir to dissolve.

[0039] 3) Pour the solution in beaker B into beaker A quickly, then vigorously stir the solution in beaker A for 5 minutes to make it fully mixed, then seal the mouth of beaker A with plastic wrap, and place beaker A in an oven at 30 degrees Celsius to keep the temperature 24 hours.

[0040]4) Take out the beaker, carefully remove the supernatant, add appropriate amount of water, transfer the solution to two 10mL centrifuge tubes,

[0041] Centrifuge at 10000rpm / min for 5 minutes, remove the supernatant, add water and ultrasonically disperse the solid. Centrifuge again 7-10 times in the same way, and dry in a 40°C oven.

[0042] 5) Mix ...

Embodiment 2

[0046] Example 2 A method of using a Prussian blue aluminum-air battery material as a positive electrode catalyst for an aluminum-air battery

[0047] 1) Mix 5g of polyvinyl alcohol, 0.5g of polyoxyethylene, and 50mL of water in a 100mL plastic beaker, put it in an oil bath, and stir at 95°C for 2 hours.

[0048] 2) Mix 5g of potassium hydroxide, 0.5g of zinc oxide, 0.15g of sodium stannate, and 5mL of water in a 25mL glass beaker, stir to dissolve and pour into the solution stirred in step 1), and continue to stir at 95°C for 1 hour .

Abstract

The invention provides a flexible aluminum-air cell material and a preparation method and applications thereof, and specifically relates to a surface modified sulfur doped Prussian blue analog nano framework aluminum-air cell positive electrode catalyst and a preparation method and applications thereof.

Description

technical field [0001] The invention belongs to the field of chemical power sources, and in particular relates to a flexible aluminum-air battery material and its preparation method and application. The material is a surface-modified sulfur-doped Prussian blue analogue nanoframe aluminum-air battery cathode catalyst. Background technique [0002] The depletion of fossil energy and environmental pollution have prompted people to explore new renewable energy and energy storage devices. As a new type of chemical power source that has emerged in recent decades, metal fuel cells have many advantages such as high efficiency and greenness, and can be used as a substitute for traditional lead-acid batteries. One of the most important ones, the aluminum-air battery, has higher specific energy and theoretical electromotive force than other non-lithium primary and secondary batteries, and the negative electrode material aluminum is cheap and easy to obtain, and is the most abundant met...
