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.

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 maybe 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.

Conclusion: 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 PCMCIA

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,

including all associated applications like Email and file

transfer.

With the wide spread 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.

* V=V1+V2=1.5A*ESR + (1.5A*1.154msec)/C

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.
