Embodiment 1

[0012] Example 1: Add 2.0×10 -2 mol / L Al 3+ Al(OH) 3 , including 3.0×10 -2 mol / L Li + LiOH, containing 2.0×10 -2 mol / L Zn 2+ ZnO, containing 1.0×10 -2 mol / LCu 2+ CuSo, containing 2.0×10 -2 mol / L Tl + TlNo 3 , including 1.5×10 -2 mol / L Pb 2+ Pb(Ac) 2 In any of them, metal ions are deposited on the surface of activated carbon in the form of alkali through the supercapacitor charge and discharge activation process.

Embodiment 2

[0013] Embodiment two: with Al 3+ , Li + , Zn 2+ 、Cu 2+ , Tl + , Pb 2+ Any one of them uses a certain method to modify the active substance-activated carbon powder, so that the ions are deposited in the micropores of the activated carbon.

[0014] Here in Pb 2+ Here is an example of how to do it:

[0015] (1) Use 0.7mol / L Pb(NO 3 ) 2 The solution was soaked in activated carbon under vacuum condition, so that Pb(NO 3 ) 2 The solution completely enters the micropores of the activated carbon, and the free solution is filtered out, and then 7mol / L NaOH solution is added and stirred to deposit Pb(OH) on the surface of the activated carbon. 2 , obtained by suction filtration to deposit Pb(OH) 2 active material, the Pb(OH) in the final active material 2 Occupy 11%, use this to make supercapacitors, deposit 11% Pb(OH) 2 , increase the specific capacity by 30.5F / g.

[0016] (2) Use 0.7mol / L Pb(NO 3 ) 2 The solution was soaked in activated carbon under vacuum condition, ...

Abstract

The treatment process of active carbon for super capacitor features the undervoltage deposition of one of the metal ion of Al3+, Li+, Zn2+, Cu2+, Ti+ and Pb2+ on the surface of active carbon to form quasi-Faraday capacitor for electrochemical double layer capacitor. Any one kind of the solution of the said ions may be added into super capaictor KOH electrolyte solution or any one kind of the solution of the said ions may be used in modifying active carbon powder to deposit the ion in the pores. The super capacitor of the present invention is matched with accumulator or other battery to constitute composite battery with high power, great capacitance and fast charging. The composite battery may be used widely in astronautic, millitary, traffic, electric power, communication and other fields.

Description

technical field [0001] The invention relates to a treatment method for activated carbon used in supercapacitors, and belongs to the technical field of supercapacitor manufacturing. Background technique [0002] The competition for the space domain and the demand for space weapons in future wars, such as laser weapons used to destroy or blind the enemy's reconnaissance and communication satellites, require high-power-density energy support. The start-up and reliable launch power support of strategic weapon delivery vehicles in alpine regions requires reliable high-power output and energy storage power devices with excellent temperature characteristics. The enhancement of people's environmental awareness makes electric vehicles or low-pollution hybrid vehicles approach human life as a clean vehicle; the requirements for high-power power during the start and acceleration of electric vehicles increase the requirements for batteries. Existing batteries are difficult to meet the ...
