Embodiment 1

[0036] The new synthesis process of adding activated carbon and two oxidants can make the yield and capacity of polyaniline in the whole synthesis process very high, which is the key indicator of future industrialization.

[0037] The production process of polyaniline synthesis is as follows: take 25L concentration as 0.5molL -1 After cooling down to below 5°C, add a certain amount of aniline (optimally 1.4kg) and react for 5 minutes; add an appropriate amount of activated carbon (optimally 170g), stir and disperse for 30min, then cool down in an ice-water bath to 0°C, then add 190 g of manganese dioxide, and react for 10 minutes. Take another 10L of hydrochloric acid of a certain concentration (1.0molL -1 ), add ammonium persulfate (optimally 3.8kg), and stir to dissolve. Under the condition of stirring, the ammonium persulfate solution was added dropwise, and the drop was controlled within 2 hours. After the dropwise addition, the stirring was continued, and the reaction w...

Embodiment 2

[0041] The production process of polyaniline synthesis is as follows: take 25L concentration as 1molL -1 Hydrochloric acid, after cooling down to below 5°C, add a certain amount of aniline (optimally 1.4kg) while stirring, and react for (how many minutes) min; add an appropriate amount of activated carbon (optimally 170g), stir and disperse for 30min, Cool down to 0°C in an ice-water bath, then add 190 g of manganese dioxide, and react for 10 minutes. Take another 10L of hydrochloric acid of a certain concentration (1.0molL -1 ), add potassium persulfate (optimally 3.8kg), and stir to dissolve. Under the condition of stirring, the potassium persulfate solution is added dropwise, and the drop is controlled within 2 hours. After the drop is completed, continue to stir and react for another 4 hours. The temperature of the entire reaction process is controlled at 5°C. After the reaction, wash with deionized water repeatedly 5 times, and then use 0.1molL -1 HCl was replaced for ...

Embodiment 3

[0044] The production process of polyaniline synthesis is as follows: take 25L concentration as 3molL -1 After cooling down to below 5°C, add a certain amount of aniline (optimally 1.4kg) and react for 5 minutes; add an appropriate amount of activated carbon (optimally 170g), stir and disperse for 30min, then cool down in an ice-water bath to 0°C, then add 190 g of manganese dioxide, and react for 10 minutes. Take another 10L of hydrochloric acid of a certain concentration (1.0molL -1 ), add sodium persulfate (optimally 3.8kg), and stir to dissolve. Under the condition of stirring, the sodium persulfate solution is added dropwise, and the drop is controlled within 2 hours. After the drop is completed, continue to stir and react for another 4 hours. The temperature of the whole reaction process is controlled at 5°C. After the reaction, wash with deionized water repeatedly 5 times, and then use 0.1molL -1 HCl was replaced for 1 h, washed with water for 3 times, and then repla...

Abstract

The invention relates to a zinc-polyaniline cell and a preparation method thereof. The technical problems of high cost, low specific energy, short service life and heavy pollution of the existing chargeable cell are solved. The cell comprises a cell positive electrode, a cell negative electrode, an electrolyte and a membrane, and the cell positive electrode is made of polyaniline and carbon composite materials. The cell can be widely applied to the field of cell preparation.

Description

technical field [0001] The invention relates to a charging and discharging device and a preparation method thereof, in particular to a zinc-polyaniline battery with low cost, high specific energy and long service life and a preparation method thereof. Background technique [0002] At present, the traditional secondary batteries mainly include lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries. The performance comparison of these four batteries is shown in Table 1. It can be seen from Table 1 that the four secondary batteries have their own advantages and disadvantages. Lead-acid batteries are the cheapest, but have the shortest cycle life, serious pollution, and the lowest specific energy. Nickel-metal hydride and nickel-cadmium batteries have twice the specific energy and longer life than lead-acid batteries, but they are seriously polluted, especially nickel-cadmium, and cadmium ions are highly toxic metal ions. The per...
