There is more attention to the development of new autonomous "physical" batteries with energy storage in the electric double layer (ultra-electrolytic capacitors with a dielectric layer between the electrodes (supercapacitors)). Supercapacitor is a new element of energy storage device with energy density 10 times higher than in the conventional capacitors, and pulse discharge capacity up to 10 times higher than the power batteries. High voltage (potential difference), to which the capacitor is charged and capacitance are important in energy area and improve the supercapacitor characteristics. For that present work new nonwoven materials with/without of inorganic inclusions (carbon or magnetite nanopatticles) are synthesized and modification of porous material to increase the amount of pore is obtained. The electrospinning technology provides continuous production of nanofibrous materials and was used for create a separator of supercapacitors in this work. Morphology and electric parameters were measured by the scanning electron microscope (Tescan Mira LMU II) and probe analyzer (Agilent), respectively. The application of energy storage of condenser type (ESCT) based on supercapacitor energy storage systems with nanofibrous materials makes it possible to reduce the installed capacity batteries and increase their lifetime by 1.5 - 2 times.
