Electrolytic capacitors, like batteries alternative
Electrolytic capacitors, as an alternative to batteries, can be used in the near future. They were used at the dawn of the electric age and now humanity is again thinking to use a capacitor as the main source of mobile energy. In this article we will talk about the possibility of using the capacitor as a battery.
The beginning of the 21st century is the widespread proliferation of all sorts of electronic gadgets, the rejection of fossil fuels and switching to electric engines. All this causes a huge demand for batteries that can store electricity. Modern batteries are quite small and require too much time to recharge. In the case of appliances, this factor plays such a big thing, as with electro-cars and other transport uses electricity as the energy source. Agree that refueling on the road, which can last from two to six hours hardly seem pleasant. That is why modern scholars consider the various types of capacitors as alternatives to batteries.
Unlike a battery, which during storage convert electrical energy into chemical, and then Vice versa, which leads to the loss of about 10% of the charge energy of the capacitor does not change, the efficiency of such storage is up to 99%. Also, the battery capacity gradually decreases depending on the number of cycles of charge-discharge, which is called «memory». Unlike a battery, a capacitor can be recharged in a few minutes. The speed of charging depends on the maximum current of the charger. The battery power is limited to the duration of it occurring in chemical processes.
Despite all the advantages of modern types of capacitors do not allow you to use them as a full replacement of batteries. Practical use found only supercapacitors, which are used in luminaires, which are powered by solar energy. Also discusses options for their use as sources of emergency power and launchers for vehicles. Perhaps in the near future they will completely replace batteries, but not in the next couple of years.
