Supercapacitor - Batteries 2.7v and 250000F
Supercapacitor - a cross between a capacitor and a battery. Small and lightweight battery with dimensions comparable to the size of today's batteries AA (or AAA), is able to be charged very quickly within minutes and quickly enough to give the stored energy, and if you want a small current consumption, it is capable of quite a long time to feed different electronics. At the same time of the advantages of ultracapacitors, compared with batteries, we can note the low weight, greater efficiency (over 95%), unipolarity (in fact, there is no + and - it all depends on how you charge), low toxicity materials, high reliability and long service life, up to several hundred thousand cycles charge - discharge and duration of up to 10 years.
on the basis of the graphene film a new type of supercapacitor that can store per unit weight as much energy as nickel-hydride batteries. But, unlike batteries, super capacitor can be charged or discharged in a few seconds. New ultracapacitor energy storage density is 285.6 Wh / kg at room temperature, and 296 Wh / kg at a temperature of 80 ° C. These values make these supercapacitors champions among supercapacitors manufactured using carbon nano materials.
