BestCap® Ultra-low ESR
High Power Pulse Supercapacitors
Introduction to BestCap®
INTRODUCING BESTCAP®: A NEW GENERATION OF 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.

Capacitance (mF)
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 volume of the BestCap®.

Cleaning/Handling/Storage Conditions/Part Marking/Termination Finish
SECTION 2: MECHANICAL SPECIFICATIONS
2.8 CLEANING
The BestCap® supercapacitor is cleaned prior to shipment. Should cleaning be required prior to insertion into the application, it is recommended to use a small
amount of propanol taking care not to remove the label. The cell should not be immersed due to possible deterioration of the epoxy encapsulation. Care must
also be taken not to bend the leads.
2.9 HANDLING
Care should be taken not to allow grease or oil into the part as it may lead to soldering problems. Handling should be minimized to reduce possible bending of
the electrodes leads.
2.10 STORAGE CONDITIONS
AVX BestCap® supercapacitor is unaffected by the following storage conditions:
Temperature:
15°C ~ 35°C
Humidity:
45% RH ~ 75% RH
This temperature and humidity range is specified for consideration of terminal solderability. BestCap® are able to withstand shelf life at 70ºC for 1000 hours.

2.13 PRODUCT SAFETY MATERIALS HANDLING
Precautions
• 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.
• 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.

Application Notes/BestCap® Construction/Voltage Drop
4.1: ELECTROCHEMICAL EDLC VS. ELECTRONIC TECHNOLOGY - BESTCAP® CONSTRUCTION
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.
To understand the benefits offered by the BestCap®, it is necessary to
examine how an electrochemical capacitor works. The most significant
difference between an electronic 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 contained in the electrolyte
which may be liquid (normally an aqueous or organic solution) or solid. The
solid electrolyte is almost universally a conductive polymer.

Figure 4. Voltage-time relation of capacitor unit
Cell Case (Anode)
The instant voltage drop ∆VESR is caused by and is directly proportional
to the capacitor’s ESR. The continuing voltage drop with time ∆VC, 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 supercapacitor
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®
Battery Voltage (Volts)
The differences between EDLC (Electrochemical Double Layer Capacitors)
and electronic capacitors are summarized in the
table below:
• 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.

Current (Amps)
Since BestCap®, when used in parallel with a battery, provides 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.
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.

Additionally, the higher-than battery voltage supplied by the BestCap® keeps
the voltage pulse above the “cut off voltage” 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).

Cutoff Voltage Limits

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 (∆V) which occur, the first ∆VESR is because of the equivalent
series resistance (ESR) and the second, called the capacitive drop, is ∆VC.

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,
∆VESR = 1 amp x (0.100) ohms = 0.1 volts or 100 milli-volts. On demand,
during the discharge mode, the voltage V = Vo

The second voltage drop is because of the capacitance. This is shown in the
equation as a linear function because of simplicity. Simply put,
Battery Alone
GSM Pulse @ 2 Amps
Q (charge) = C (capacitance) x V (voltage)
Figure 6a. Li-ION Battery at +25°C
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 ∆V C is 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 ∆V C = 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 milliseconds, and the capacitance is 100 millifarads, the ∆VC
= 1 x (10/1000)/(100/1000) = 0.1 volt or 100 millivolts. 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.

BestCap® Ultra-low ESR
High Power Pulse Supercapacitors
Enhancing the Power Capability of Primary Batteries
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
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.
The following analysis compares a primary battery connected 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.
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 traditional approach involves using a
high power rechargeable battery, charged by a low power primary cell.
BestCap® 5.5V 100mF
A far superior solution, however, is the use of a BestCap® Supercapacitor,
which is a device specifically designed to deliver high power.

The PCMCIA card is used as an accessory to Laptops and PDAs and enables
wide area mobile Internet access, including 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 approximately 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.
Conclusion: 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.
