BestCap®Ultra-low ESR
High Power Pulse Supercapacitors
Supercapacitors (also referred to as Electrochemical
Capacitors or Double Layer Capacitors) have rapidly become
recognized, not only as an excellent compromise between
“electronic” or “dielectric” capacitors such as ceramic,
tantalum, film and aluminum electrolytic, and batteries (Figure
1), but also as a valuable technology for providing a unique
combination of characteristics, particularly very high energy,
power and capacitance densities.
There are, however, two limitations associated with
conventional supercapacitors, namely: high ESR in the tens
of Ohms range, and high capacitance loss when required to
supply very short duration current pulses. BestCap®
successfully addresses both of these limitations.
The capacitance loss in the millisecond region is caused by
the charge transfer (i.e. establishment of capacitance) being
carried out primarily by relatively slow moving ions in double
layer capacitors.
In the above-mentioned “electronic” capacitors, the charge
transfer is performed by fast electrons, thereby creating
virtually instant rated capacitance value. In the BestCap®, a
unique proton polymer membrane is used – charge transfer
by protons is close to the transfer rate for electrons and
orders of magnitude greater than organic molecules. Figure
2 below illustrates the severe capacitance loss experienced
by several varieties of supercapacitors under short pulse
width conditions. It can also be seen from Figure 2 how well
BestCap®retains its capacitance with reducing pulse widths.
For comparison purposes, the characteristic of an equivalent
capacitance value aluminum electrolytic capacitor is shown
in Figure 2. The electrolytic capacitor is many times the vol-
ume of the BestCap®.

2.13 PRODUCT SAFETY MATERIALS HANDLING
Precautions
• Do not disassemble the capacitor.
• Do not incinerate the capacitor and do not use incineration
for disposal.
The capacitor contains polymeric electrolyte and carbon
electrodes. However, since the polymer is composed of
acid based chemical ingredients, if punctured or
dismantled and the skin is contacted with the capacitor
internal components, it is recommended to wash the skin
with excess of running water.
If any internal material contacts the eyes, rinse thoroughly
with running water.
Be aware not to apply over-voltage. Combination of
charging at voltage greater than the nominal, plus high
temperature, plus prolonged time may result in capacitor
bulging or rupturing.
BestCap®is RoHS compliant
May be assembled with Pb-Free solder.

High Power Pulse Supercapacitors
4.1: ELECTROCHEMICAL EDLC VS.
ELECTRONIC TECHNOLOGY -
BESTCAP®CONSTRUCTION
To understand the benefits offered by the BestCap®, it is
necessary to examine how an electrochemical capacitor
works. The most significant difference between an electron-
ic capacitor and an electrochemical capacitor is that the
charge transfer is carried out by the electrons in the former
and by electrons and ions in the latter. The anions and
cations involved in double layer supercapacitors are con-
tained in the electrolyte which may be liquid (normally an
aqueous or organic solution) or solid. The solid electrolyte is
almost universally a conductive polymer.
Electrons are relatively fast moving and therefore transfer
charge “instantly.” However, ions have to move relatively
slowly from anode to cathode, and hence a finite time is
needed to establish the full nominal capacitance of the
device. This nominal capacitance is normally measured at
1 second.
The differences between EDLC (Electrochemical Double
Layer Capacitors) and electronic capacitors are summarized
in the table below:
4.2: VOLTAGE DROP
Two factors are critical in determining the voltage drop when
a capacitor delivers a short current pulse; these are ESR
and “available” capacitance as shown in Figure 4.
Figure 4. Voltage-time relation of capacitor unit
The instant voltage drop ΔVESR is caused by and is directly
proportional to the capacitor’s ESR. The continuing voltage
drop with time ΔVC, is a function of the available charge, i.e.
capacitance. From Figures 3 and 4 it is apparent that, for
very short current pulses, e.g. in the millisecond region, the
combination of voltage drops in a conventional supercapaci-
tor caused by a) the high ESR and b) the lack of available
capacitance causes a total voltage drop, unacceptable for
most applications. Now compare the BestCap®performance
under such pulse conditions. The ultra-low ESR (in
milliOhms) minimizes the instantaneous voltage drop, while
the very high retained capacitance drastically reduces the
severity of the charge related drop. This is explained further
in a later section.
EFFICIENCY/TALKTIME BENEFITS OF BESTCAP®
Since BestCap®, when used in parallel with a battery, pro-
vides a current pulse with a substantially higher voltage than
that available just from the battery as shown in Figure 5, the
efficiency of the RF power amplifier is improved.
Figure 5. GSM Pulse
Additionally, the higher-than battery voltage supplied by the
BestCap®keeps the voltage pulse above the “cut off volt-
age” limit for a significantly longer time than is the case for
the battery alone. This increase in “talk time” is demonstrated
in Figures 6(a) (Li-Ion at +25°C), and 6(b) (Li-Ion at 0°C).

SECTION 4: APPLICATION NOTES
A capacitor basically consists of two conductive plates
(electrodes), separated by a layer of dielectric material.
These dielectric materials may be ceramic, plastic film,
paper, aluminum oxide, etc.
EDLCs do not use a discrete dielectric interphase
separating the electrodes.
EDLCs utilize the charge separation, which is formed
across the electrode – electrolyte interface.
The EDLC constitutes of two types of charge carriers:
IONIC species on the ELECTROLYTE side and
ELECTRONIC species on the ELECTRODE side.

PULSE CAPACITOR APPLICATIONS
As mentioned earlier, the voltage drop in a circuit is critical
as the circuit will not operate below a certain cut-off voltage.
There are two sources of voltage drop (ΔV) which occur, the
first ΔVESR is because of the equivalent series resistance
(ESR) and the second, called the capacitive drop, is ΔVC.
From Ohm’s law,
voltage = current x resistance or V = IR
Let us say that the instantaneous starting voltage is Vo, or
voltage for the circuit from where the voltage drops. If the
capacitor has an ESR of 100 milliOhms and the current is 1
amp,
ΔVESR = 1 amp x (0.100) ohms = 0.1 volts or 100 milli-volts.
On demand, during the discharge mode, the voltage V = Vo
- ΔVESR = (Vo - 0.1) volts
The second voltage drop is because of the capacitance.
This is shown in the equation as a linear function because of
simplicity. Simply put,
Q (charge) = C (capacitance) x V (voltage)
The derivative, dQ/dt = I (current, in amps) = C x dV/dt
Hence, ΔVC(dV, the voltage drop because of capacitance) =
I x dt/C. This formula states that the larger the capacitance
value the lower the voltage drop. Compared to a Ta capacitor,
this ΔVCis reduced by a factor of about 10 to 100. So,
BestCap®has an advantage where higher capacitance is
needed. If the current pulse itself is 1 amp, the current pulse
width is 1 second and the capacitance is 10 millifarads, the
ΔVC= 1A x 1Sec/0.01F, or a 100 volts; such an application
is out of the range of BestCap®. However, if the pulse width
becomes narrower, say 10 milli-seconds, and the capaci-
tance is 100 millifarads, the ΔVC= 1 x (10/1000)/(100/1000)
= 0.1 volt or 100 milli-volts. This shows the advantage of the
large capacitance and hence the term “pulse” capacitor.
The specific power – specific energy graphs are used in the
battery industry to compare competitive products. As the dt
becomes smaller i.e.100 milliseconds, 10 milliseconds and
then 1 millisecond, our estimates show that the specific
power for the BestCap®is the highest as compared to our
competitors because of our choice of internal materials
chemistry.
Concl usi on: we now clearly show that BestCap®has an
advantage over competitors for short current pulse whose
widths are smaller than a few hundred milliseconds.

4.3 ENHANCING THE POWER
CAPABILITY OF PRIMARY BATTERIES
When electronic equipment is powered by a primary (non
rechargeable) battery, one of the limitations is the power
capability of the battery.
In order to increase the available current from the battery
while maintaining a constant voltage drop across the battery
terminals, the designer must connect additional cells in
parallel, leading to increased size and cost of both the
battery and the finished product.
When high power is only required for short periods, more
sophisticated approaches can be considered. The tradition-
al approach involves using a high power rechargeable
battery, charged by a low power primary cell.
A far superior solution, however, is the use of a BestCap®
Supercapacitor, which is a device specifically designed to
deliver high power.
Traditional design:
Design using BestCap®:
BestCap®Supercapacitor benefits to the designer are:
Substantially lower voltage drop for pulse durations of up
to 100msec.
Substantially lower voltage drop at cold temperatures
(–20°C).
• Discharge current limited only by the ESR of the capacitor
The following analysis compares a primary battery connect-
ed in parallel to a Lithium Tionil Chloride, to the same
primary battery connected to a BestCap®Supercapacitor.
Various current pulses (amplitude and duration) are applied
in each case.

4.4 BESTCAP®FOR GSM/GPRS PCM-
CIA MODEMS
There is an increasing usage of PCMCIA modem cards for
wireless LAN and WAN (Wide Area Network) applications.
The PCMCIA card is used as an accessory to Laptops and
PDAs and enables wide area mobile Internet access, includ-
ing all associated applications like Email and file transfer.
With the widespread use of GSM networks, a PCMCIA
GSM modem is a commonly used solution. To achieve
higher speed data rates, GSM networks are now being
upgraded to support the GPRS standard.
The design challenge:
GSM/GPRS transmission requires a current of approximate-
ly 2A for the pulse duration. The PCMCIA bus cannot supply
this amount of pulsed current. Therefore, there is a need for
a relatively large capacitance to bridge the gap.
The capacitor supplies the pulse current to the transmitter
and is charged by a low current during the interval between
pulses.

It is assumed that during the pulse, 0.5A is delivered by the
battery and 1.5A by the capacitor.
Concl usi on: High capacitance is needed to minimize voltage
drop. A high value capacitance, even with a higher ESR,
results in a lower voltage drop. Low voltage drop minimizes
the conductive and emitted electro magnetic interference
and increases transmitter output power and efficiency.
