example 1

[0023] Example 1: The supercapacitor storage battery provided in this embodiment is mainly used for the No. 1 rechargeable battery.

[0024] Choose a lead foil with a thickness of 0.05mm, spray a mixture of PTFE, graphene, and activated carbon with a thickness of 0.01mm, and the ratio of PTFE, graphene, and activated carbon is 1:1:8, and then treat it according to the conventional formula. After coating the lead foil, the total thickness of the plate after coating the lead paste is 0.2mm, and then select a separator with a thickness of 0.2mm, and wrap the sheet according to the method of separator-negative plate-separator-positive plate. A super capacitor is wound into a battery, and the dimensions of the battery are as follows: hollow 5mm, diameter 30mm, height 50mm. Its capacity can reach 4Ah. Performance and cost performance are higher than AA rechargeable Ni-MH batteries of the same size.

The charging acceptance capacity and high current discharge capacity a...

preparation example 1

[0029] Take 1Kg of water, add 20g of PTFE under the condition of constant stirring, after the PTFE is completely dissolved, continue to stir, add 20g of graphene, after the graphene is added, disperse the mixed solution with a high-speed disperser, and finally process it The active material composite layer material was loaded into the spray gun, and a uniform layer of active material composite layer material with a thickness of 5 μm was sprayed on both sides of the 0.05 mm thick lead foil. Compared with the wound lead-acid battery that has not been treated with the lead foil, the wound lead-acid battery prepared with the lead foil treated with the active material composite layer material has a very large advantage in life.

Abstract

The invention discloses a super capacitor battery. A positive pole plate, a negative pole plate and partition plates are wrapped according to a mode of partition plate-negative pole plate-partition plate-positive pole plate to form a super capacitor spiral battery. The super capacitor battery is characterized in that the positive pole plate and the negative pole plate have the same structure and are of a five-layer composite structure composed of a lead foil layer in the middle, active material compound layers at the two sides of the lead foil layer and lead paste layers at the two sides of the active material compound layers, wherein the thickness of the lead foil is 0.01-0.1 mm, the lead foil is provided with holes of which the diameter is 0.01-0.02mm, the active material compound layers are composed of a compound of binder and carbon material, and the active material compound layers are 0.005-0.01mm thick. The current collector of the super capacitor battery has large surface area and strong conductive capability. The pole plates are thinner, and the surface area is increased sharply. Full play can be given to the energy density and power density of the super capacitor battery. Furthermore, full play can be given to the characteristics of activated carbon super capacitors, and the HRPSoc life is improved.

Description

technical field [0001] The invention belongs to the field of batteries, and in particular relates to a supercapacitor storage battery. Background technique [0002] With the continuous development of the economy, energy, resources and the environment have become the focus of society. Finding clean, renewable and resource-saving energy is a very urgent and arduous task for human society. All kinds of lead-acid batteries are cost-effective, safe, easy to use and maintain, mature in production technology and friendly to the environment, renewable, and are increasingly becoming the preferred batteries for various electric vehicles, communication power supplies and UPS power lights. However, due to the limitations of the electrochemical system of lead-acid batteries, the mass density and power density of the battery are low, and the cycle life of the battery is low when it is suitable as a power battery, especially as an energy storage battery and a hybrid of a photovoltaic syste...
