Ultracapacitor : Introduction
LS Ultracapacitor (Supercapacitor) is promising energy storage device that positioned between conventional electrolytic capacitor and
rechargeable batteries. High power, high energy and long-term reliability feature of LS Ultracapacitor (Supercapacitor) enable this component
to use in various applications as backup power unit, auxiliary power unit, instantaneous power compensation, peak power compensation and
energy storage as well.
LS Ultracapacitor provides optimum design of package to have the best performance and reliability.
Ultracapacitor (Supercapacitor) is composed of two elec
trodes immersed in electrolyte, and its porous dielec
tric separator prevents short circuit of two electrodes.
Ultracapacitor (Supercapacitor)stores energy relied on
electrostatic charges on opposite electrode surface of the
electric double layer, which is formed between each of the
electrodes and the electrolyte.
Randomly distributed ions in electrolyte move toward the
electrode surface of opposite polarity under electric field
when charged. It is purely physical phenomena rather than
though a chemical reaction and highly reversible process,
which result in high power, high cycle life, long shelf life, and
