Example Embodiment

[0035] Example 1

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

[0037] The production process of polyaniline synthesis is as follows: take 25L concentration as 0.5molL -1 After cooling to below 5℃, add a certain amount of aniline (1.4kg is the best) under stirring, and react for 5min; add a proper amount of activated carbon (170g), stir and disperse for 30min, then cool in an ice-water bath After reaching 0°C, 190 g of manganese dioxide was added and reacted for 10 minutes. Take another 10L of a certain concentration of hydrochloric acid (1.0molL -1 ), add ammonium persulfate (the best is 3.8kg), stir to dissolve. Under the condition of stirring, the ammonium persulfate solution was dripped in by dripping, and the dripping was controlled at 2h. After the dripping was completed, the stirring was continued, and t...

[0040] Example 2

[0041] The production process of polyaniline synthesis is as follows: take 25L concentration as 1molL -1 After cooling the temperature to below 5℃, add a certain amount of aniline (1.4kg is the best) under stirring, and react (how many minutes) for min; add an appropriate amount of activated carbon (170g), stir and disperse for 30min, Cool down to 0°C in an ice water bath, then add 190g of manganese dioxide and react for 10 minutes. Take another 10L of a certain concentration of hydrochloric acid (1.0molL -1 ), add potassium persulfate (the best is 3.8kg), stir to dissolve. Under the condition of stirring, the potassium persulfate solution was dripped in by dripping, and the dripping was controlled at 2h. After the dripping was completed, the stirring was continued, and the reaction was continued for 4h. The temperature of the entire reaction process was controlled to 5°C. After the reaction is over, rinse with deionized water 5 times, then use 0.1molL -1 The ...

[0043] Example 3

[0044] The production process of polyaniline synthesis is as follows: take 25L concentration as 3molL -1 After cooling to below 5℃, add a certain amount of aniline (1.4kg is the best) under stirring, and react for 5min; add a proper amount of activated carbon (170g), stir and disperse for 30min, then cool in an ice-water bath After reaching 0°C, 190 g of manganese dioxide was added and reacted for 10 minutes. Take another 10L of a certain concentration of hydrochloric acid (1.0molL -1 ), add sodium persulfate (the best is 3.8kg), stir to dissolve. Under the condition of stirring, the sodium persulfate solution was dripped in by dripping, and the dripping was controlled at 2h. After the dripping was completed, the stirring was continued, and the reaction was continued for 4h. The temperature of the entire reaction process was controlled to 5°C. After the reaction is over, rinse with deionized water 5 times, then use 0.1molL -1 The HCl was replaced with HCl for ...

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...
