With the development of mobile communication technology, cell phone has become an essential communication tool in people’s daily life. However, as the functions of cell phones become richer and richer, the power consumption also increases, and the standby time of cell phone battery becomes shorter and shorter. The charging time of cell phone is long, usually takes several hours, therefore, the charging problem of cell phone becomes one of the problems that consumers are worried about. Film capacitor price for many manufacturers, the battery has also become one of the obstacles that restrict the development of their cell phones.

At present, cell phone batteries generally use lithium batteries and nickel-cadmium batteries to supply power. As the NiCd battery has a serious memory effect, and the energy to volume ratio is also smaller, so it is gradually replaced by the better performance of lithium batteries. In recent years, as the price of lithium batteries has fallen, the trend of its replacement for NiCd batteries has become increasingly obvious. But in general, these two batteries have inherent defects because they are batteries themselves, such as high current charging will damage the battery, and waste batteries are polluting to the environment.
Supercapacitor is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and green environment protection, etc. It is called “green energy”. Compared with lithium battery, supercapacitor has fast charging speed, which can reach more than 95% of its rated capacity in 10 seconds-10 minutes; long charging life, which can be repeatedly charged and discharged hundreds of thousands of times, fast charging and discharging speed, no pollution to the environment, long cycle life, etc. Since the electrical energy contained in the equivalent volume of supercapacitor is close to the capacity of lithium battery, it can be used as an independent power source.
