超级法拉电容可以当电池用吗？想要知道答案首先我们要知道法拉电容属于双电层电容器，其基本原理是利用活性炭多孔电极和电解质组成的双电层结构获得超大的容量。一张图片告诉你超级电容的结构特点，如下图：
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:
超级电容器类似于普通电解电容，都有一个正极和一个负极，两个电极之间有一层隔膜，在正负极和隔膜之间以电解液填充，可看出多孔化电极有更多的表面积去吸附电解液的电荷，因此容量可以达到很大。隔膜一般是纤维结构的电子绝缘材料，而电解液材料一般是根据引出电极材料选择。
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.
法拉电容是可以充当电池使用的，因为它具有以下优点：
Faraday capacitors can be used as batteries because they have the following advantages:
1. 充电速度快，充电10秒～10分钟可达到其额定容量的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. 循环使用寿命长，深度充放电循环使用次数可达1~50万？危挥？“记忆效应”；
The cycle life is long, and the cycle times of deep charge discharge can reach 10 ~ 500000? Danger? "Memory effect";
3.大电流放电能力超强，能量转换效率高，过程损失小，大电流能量循环效率≥90%；
High current discharge capacity, high energy conversion efficiency, small process loss, large current energy cycle efficiency ≥ 90%;
4.功率密度高，可达300W/KG~5000W/KG，相当于电池的5~10倍；
High power density, up to 300W / kg ~ 5000W / kg, equivalent to 5 ~ 10 times of the battery;
使用时候直接当普通电池使用就行了。
When using, it can be used as a normal battery.
超级电容在汽车领域当中可以作为汽车的启动电源，比传统蓄电池电源性能好；在UPS不间断电源当中，用超级电容器可以提供瞬时功率输出，作为备用电源；作为激光器脉冲能源以及其他设备储能能源等。
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.
