超級法拉電容可以當電池用嗎？想要知道答案首先我們要知道法拉電容屬于雙電層電容器，其基本原理是利用活性炭多孔電極和電解質組成的雙電層結構獲得超大的容量。一張圖片告訴你超級電容的結構特點，如下圖：
Can super farad capacitors be used as batteries? In order to know the answer, first of all, we should know that farad capacitor belongs to electric double-layer capacitor. Its basic principle is to use the double-layer structure composed of activated carbon porous electrode and electrolyte to obtain super large capacity. A picture shows you the structural characteristics of supercapacitors, as shown in the following figure:
超級電容器類似于普通電解電容，都有一個正極和一個負極，兩個電極之間有一層隔膜，在正負極和隔膜之間以電解液填充，可看出多孔化電極有更多的表面積去吸附電解液的電荷，因此容量可以達到很大。隔膜一般是纖維結構的電子絕緣材料，而電解液材料一般是根據引出電極材料選擇。
Supercapacitors are similar to ordinary electrolytic capacitors. They have a positive electrode and a negative electrode. There is a layer of diaphragm between the two electrodes. The electrolyte is filled between the positive and negative electrodes. It can be seen that the porous electrode has more surface area to absorb the charge of the electrolyte, so the capacity can be large. The diaphragm is generally a fiber structure of electronic insulation material, and the electrolyte material is generally selected according to the lead out electrode material.
法拉電容是可以充當電池使用的，因為它具有以下優點：
Faraday capacitors can be used as batteries because they have the following advantages:
1. 充電速度快，充電10秒～10分鐘可達到其額定容量的95％以上；
The charging speed is fast, and it can reach more than 95% of its rated capacity in 10 seconds to 10 minutes;
2. 循環使用壽命長，深度充放電循環使用次數可達1~50萬？危揮？“記憶效應”；
The cycle life is long, and the cycle times of deep charge discharge can reach 10 ~ 500000? Danger? "Memory effect";
3.大電流放電能力超強，能量轉換效率高，過程損失小，大電流能量循環效率≥90%；
High current discharge capacity, high energy conversion efficiency, small process loss, large current energy cycle efficiency ≥ 90%;
4.功率密度高，可達300W/KG~5000W/KG，相當于電池的5~10倍；
High power density, up to 300W / kg ~ 5000W / kg, equivalent to 5 ~ 10 times of the battery;
使用時候直接當普通電池使用就行了。
When using, it can be used as a normal battery.
超級電容在汽車領域當中可以作為汽車的啟動電源，比傳統蓄電池電源性能好；在UPS不間斷電源當中，用超級電容器可以提供瞬時功率輸出，作為備用電源；作為激光器脈沖能源以及其他設備儲能能源等。
In the automotive field, super capacitor can be used as the starting power supply of the car, which has better performance than the traditional battery power supply; in the UPS UPS, the super capacitor can provide instantaneous power output as the backup power supply; as the laser pulse energy and other equipment energy storage energy.
