Capacitor with dual electric layer

The invention relates to electrical engineering, in particular, to capacitor-making industry and can find application in producing high-capacity electric capacitors making use of double electric layer (DEL). Capacitors with DEL have found application as stand-by power sources in systems requiring uninterrupted power supply, such as computation engineering, communications equipment, numerically controlled machine tools, in uninterrupted cycle production processes; for electric-starter starting of diesel engines; for power supply of invalid carriages, golf carriages, and so on. A capacitor with dual electric layer, wherein one of the electrodes is made of a porous carbon material and the other capacitor, of a material containing lead sulfate. The capacitor features enhanced characteristics and lower cost.
