    2018-04-04
    The advantages of EDLC over standard capacitors and batteries make them ideal alternatives. These advantages include: more charge and discharge times than rechargeable batteries, higher actual efficiency of 98, lower internal resistance, higher output power, better thermal performance, better safety
  • [industry information] Analysis of Super Capacitor
    2018-04-04
    In principle, supercapacitors can be thought of as a rechargeable battery. It can store charges that are proportional to its capacity and release them when the discharge is required. The biggest difference between super capacitors and electrolytic capacitors is their electronic bilayer structure, wh
  • [industry information] What's a Super Capacitor?
    2018-04-04
    Super capacitors, which are mainly used for high-power power sources and large industrial and consumer power supplies, are now finding opportunities to use their talents in products of all sizes, especially portable devices. Super capacitors are well known for their capacitance values and rapid char
