Farad (short for "fa"), with the symbol F;

1 Farad Yes Farad capacitor When storing 1 coulomb of electricity, the potential difference between the two plates is 1 volt 1F=1C/1V;

1 coulomb is the electric quantity transported by 1A current within 1s, that is, 1C=1A · S;

1 coulomb=1 ampere second;

1 Farad=1 A · s/volt;

The discharge capacity of the battery (storage battery) at 12V 14A=14 * 3600 * 1/12=4200 Farad (F), (Note: the 12V 14A battery is composed of 6 2v14A hours in series. If it is changed to 6 fast parallel, it is equal to 2v84A hours, and if it is converted to 1V, it is 168A hours). The earth's capacitance is only about 1-2F.

Super capacitor manufacturer The reason why it is called "super":

The supercapacitor can be regarded as two non reactive porous electrode plates suspended in the electrolyte. When the electrode plate is electrified, the positive plate attracts the negative ions in the electrolyte, and the negative plate attracts the positive ions. In fact, it forms two capacitive storage layers. The separated positive ions are near the negative plate, and the negative ions are near the positive plate.

Super capacitor module Supercapacitors store energy in separated charges. The larger the area used to store charges, the denser the separated charges, and the larger the capacitance.

The area of the supercapacitor is based on the data of porous carbon, whose porous structure allows its area to reach 2000m2/g, and some measures can be taken to achieve a larger surface area. The charge separation interval of Farad capacitor is determined by the scale of electrolyte ions attracted to the charged electrode. This interval (<10 ∨) is smaller than that of traditional capacitor film materials.

The huge surface area and very small charge separation distance make supercapacitors have a surprising electrostatic capacity compared with traditional capacitors, which is also where their "super" lies.

The area of the traditional capacitor is the flat area of the conductor. In order to obtain larger capacity, the conductor data is rolled very long, and sometimes special arrangement structure is used to add its surface area. Traditional capacitors are separated from their bipolar plates by insulating materials, which are generally plastic film, paper, etc. These materials are generally required to be as thin as possible.
