Part 2: User Manual
1. Background
Film capacitors store charge by means of two layers of conductive film that are separated by a dielectric material. The charge accumulates on both
conductive film layers, yet remains separated due to the dielectric between the conductive films.
Electrolytic capacitors are composed of metal to which is added a thin layer of nonconductive metal oxide which serves as the dielectric.
These capacitors have an inherently larger capacitance than that of standard film capacitors.
In both cases the capacitance is generated by electronic charge and therefore the power
capability of these types of capacitors is relatively high while the
energy density is much lower.
The Electrochemical Double Layer Capacitor (EDLC) or Super Capacitor is a form of
hybrid between conventional capacitors and the battery.
The electrochemical capacitor is based on the double layer phenomena
occurring between a conductive solid and a solution interphase.
The capacitance, coined the "double layer capacitance", is the result of charge separation in the interphase. On the solid electrode, electronic charge is
accumulated and in the solution counter charge is accumulated in the form of ionic
charge.
The EDLC embodies high power and high energy density (Fig. 1).

Revision: 21-3-10

Electrochemical Capacitors
The operating principle of the super capacitor is similar to that of a battery. Pairs of
electrodes are separated by an ionic conductive, yet electrically
insulating, separator (Fig. 2). When a super capacitor is charged, electronic charge
accumulates on the electrodes (conductive carbon) and ions (from the electrolyte) of
opposite charge approach the electronic charge.
This phenomenon is coined "the double layer phenomenon".
The distance between the electronic and the ionic charges is very small, roughly 1
nanometer, yet electronic tunneling does not occur.
Between charging and discharging, ions and electrons shift locations.
In the charged state a high concentration of ions will be located along the
electronically charged carbon surface (electrodes).
As the electrons flow through an external discharge circuit, slower moving ions will
shift away from the double layer. During EDLC cycling electrons and ions constantly
move in the capacitor, yet no chemical reaction occurs.
Therefore electrochemical capacitors can undergo millions of charge and
discharge cycles. This phenomenon which occurs with carbon electrodes of very high
surface area and a three-dimensional structure, leads to incredibly high capacitance
as compared to standard capacitors.
One can envision the model of the EDLC as two capacitors formed by the solid
(carbon) liquid (electrolyte) interphase separated by a conductive ionic
membrane. An equivalent electronic model is two capacitors in a series
connection (Fig. 3) where Cdl is the capacitance of each electrode; Rp is the
parallel resistance to the electrode, Rs is the resistance of the separator.
We conclude that the energy density of electrochemical capacitors is higher than that
of electrolytic capacitors, and therefore they have applicability for systems with lower
frequency requirements.

Cellergy’s Technology
By use of a unique patented production and manufacturing process,
Cellergy has developed a small footprint, low Equivalent Series Resistance
(ESR), high frequency EDLC capable of storing relatively large amounts of
energy.
The development is based on an innovative printing technology allowing the
production of EDLC’s in many different sizes with varied dimensions and
shapes.
In fact, Cellergy produces one of the smallest low ESR footprint EDLC's on
the market today.
Since the patented printing technology is based on conventional printing
techniques, the manufacturing process is simple and unique, and it is possible to manufacture large wafers of EDLC's.
The basis of the technology is a printable aqueous electrode paste based on a
high surface area carbon paste that is printed in an electrode matrix
structure on an electronically conductive film.
The electrodes are then encapsulated with a porous ionic conducting
separator and another electrode matrix is then printed on the separator.
This bipolar printing process is repeated as many times as required enabling
us to tailor our product to the specifications of the end user.
The finished wafer is then cut into individual EDLC's that are then packaged.
Cellergy's EDLC's boasts low equivalent series resistance as well as a low
leakage current due to our unique encapsulation technology and electrode
composition.
Cellergy's EDLC's require no cell balancing or de-rating.
The combination of the separator and carbon paste lead to the capability of
very high power bursts within low milli-second pulse widths.
Cellergy’s technology is based on aqueous components that are all
environmentally friendly and non-toxic. Though the system is water based,
the capacitor can work at temperatures between -40°C and 70°C.
This working temperature range is achieved by the unique water based
electrolyte that impregnates the high surface carbon.
Because the chemistry of the system is based on water, the performance of
Cellergy's EDLC's is not affected by humidity.

Voltage Drop
Two main factors affect the voltage drop of all capacitors including EDLC's.
The first voltage drop is defined as the Ohmic voltage drop.
The capacitor has an internal resistance defined as ESR (Equivalent Series Resistance).
As current flows through the capacitor, a voltage drop occurs that obeys Ohms
law. This voltage drop is instantaneous and will diminish the
moment that no current is drawn.
The second voltage drop (capacitance related voltage drop) is due to
capacitor discharge.
The voltage of the capacitor is directly proportional to the charge
accumulated in the capacitor. During current discharge, capacitance is
consumed (current emitting from the capacitor) thus causing a linear
voltage decrease in the capacitor. When the current is stopped, the voltage of the
capacitor indicates the charge left in the capacitor. The combination of the Ohmic related voltage drop and the capacitance related voltage drop determine the
actual working voltage window of an EDLC under drain conditions (Fig. 4).

EDLC and Battery Coupling
Under drain conditions, a battery undergoes a voltage drop similarly to the
EDLC. Because of many physical and chemical constraints, the
battery often cannot supply the power required while still retaining its
open circuit voltage.
The working voltage of the battery reflects the load on the battery, thus the
larger the voltage drop of the battery the larger the load on the
battery.
Many difficulties are encountered by the designer planning the online
power demand of a system, mainly because the power of the batteries is
limited.
If the battery must supply high power at short pulse widths, the voltage
drop may be too great to supply the power and voltage required by the end
product (cutoff voltage).
The large load on the battery may decrease the useful energy stored in the
battery and even may harm the battery and shorten its work life.
This problem may be resolved by connecting the battery in parallel to an
EDLC (Fig. 5).

EDLC and Battery Coupling (Continued)
Voltage
Under conditions of high power and short duration current pulses, a voltage damping effect will be achieved. The voltage drop of the
battery will be decreased resulting in better energy management and
superior energy density of the battery (Fig. 6).
The power supplied will be produced by both the EDLC and the
battery, and each will supply the relative power inversely to its own ESR.
The inefficiency of batteries at lower temperatures is well known.
The capacitance of most batteries decreases with decreasing
temperatures.
This decrease is due to the slow kinetics of the chemical reaction in the
battery which increases the internal resistance of the battery.
At low temperatures, the voltage drop of the battery increases and
reduces the usefulness of the battery. This voltage drop can be
reduced greatly by coupling of the battery and the EDLC.
In conclusion, coupling the battery and EDLC results in superior power
management for many short interval and high power
applications..

Handling Cautions
1) Do not apply more than rated voltage.
If you apply more than rated voltage, Cellergy electrolyte will be electrolyzed and the super capacitors ESR may increase.
2) Do not use Cellergy for ripple absorption.
3) Operating temperature and life
Generally, Cellergy has a lower leakage current, longer back-up time
and longer life in the low temperature range i.e. the room temperature.
It will have a higher leakage current and a shorter life at elevated temperatures.
Please design the Cellergy such that is not adjacent to heat emitting
elements.
4) Short-circuit Cellergy
You can short-circuit between terminals of Cellergy without a resistor.
However when you short-circuit frequently, please consult us.
5) Storage
In long term storage, please store Cellergy in following condition;
1) TEMP. : 15 ~ 25 °C
2) HUMIDITY: 45 ~ 75 %RH
3) NON-DUST
6) Do not disassemble Cellergy. It contains electrolyte.
7) The tips of Cellergy terminals are very sharp. Please handle with care.
8) Reflow process is not recommended for Cellergy capacitors.
Note
The Cellergy EDLC is a water based component. Extended use of the EDLC at elevated
temperatures may cause evaporation of water leading to ESR increase.
