>> Introduction to LS Ultracapacitor Cell
Structure
Ultracapacitor is consisted of two electrodes immersed in an electrolyte and separator prevents the charge from moving between two
electrodes having different polarity.
LS Cable provides optimum design of package to have the best performance and reliability.
Operating Principle
Ultracapacitor 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 through a chemical reaction and highly reversible
process, which result in high power, high cycle life, long shelf life, and maintenance-free product.
>> Difference among LS Ultracapacitor & other energy storage devices
High Energy & High Power
Ultracapacitor is unique energy storage device to offer
high power and high energy simultaneously compared
with conventional electrolytic capacitor and battery.
The high content of energy stored by Ultracapacitor in
comparison to conventional electrolytic capacitor is
came from activated carbon electrode material having
the extremely high surface area and the short distance
of charge separation created by the opposite charges in
the interface between electrode and electrolyte.
High power, long shelf and cycle life performance of
Ultracapacitor originate in the energy storage
mechanism differing from battery. In battery, energy is
stored and released via chemical reaction inside
electrode material that cause degradation of overall
system. On the other side, Ultracapacitor uses
physically charge separation phenomena between
charge on electrode and ions in electrolyte at the
interface. Since charge and discharge process are
purely physical and highly reversible, Ultracapacitor can
release energy much faster (with more power) than a
battery that relies on slow chemical reactions and can
be cycled hundreds of thousands of times without deep
effect on performance.
Charge & Discharge
Ultracapacitor is an energy storage device that has different charge & discharge characteristics compared with rechargeable battery. Battery has
voltage plateau region but Ultracapacitor shows only linear relationship with voltage during charge and discharge. The linear relationship with
voltage can change to constant voltage by simply connecting DC-DC converter. The amount of energy stored in Ultracapacitor can be easily
calculated by measuring voltage.
Energy Equation for Ultracapacitor
Different unit between Ultracapacitor(Farad) and battery(Ampere hour) make user to confuse when adopting Ultracapacitor in their
system. The amount of energy stored in Ultracapacitor can be easily calculated by using following equation.
Energy (Joule) = 1/2 x Capacitance (Farad) x Voltage2 (Volt)
It can be converted from Farad for Ultracapacitor to Watt hour unit which is normally used for conventional rechargeable battery.
Energy (Watt hour) = Energy (Joule) / 3600 (sec)
LS Cable recommends to operate Ultracapacitor from maximum voltage to half voltage and release 3/4 of total energy.
>> Introduction to LS Ultracapacitor Module
LS Ultracapacitor Module provides leading solution for high voltage and current required application by connecting 3000F Ultracapacitor unit
cell in series. Higher voltage and capacitance module can be built simply by connecting the modules.
Low internal resistance and high working voltage features of module maximize its available energy while keeping maintenance free, high
reliability and wide operating temperature features of LS Ultracapacitor unit cell.
