- A super
capacitor is basically two parallel conducting plates separated by
an insulating material known as a dielectric. The value of the
capacitor is directly proportional to the area of the plates and
inversely proportional to the thickness of the dielectric.
Manufacturers building “super” capacitors achieve higher levels of
capacitance while minimizing size by using a porous carbon material
for the plates to maximize the surface area and a molecularly thin
electrolyte as the dielectric to minimize the distance between the
plates.
- Some of the
most attractive features in wireless and portable devices today
demand high levels of current for very short durations
- “super”
capacitors offer high levels of capacitance in a relatively small
case size.
- Working with
the battery and a DC/DC converter, a super capacitor discharges its
power during peak loads and recharges between peaks, providing the
power needed to operate systems from battery operated hosts.
- By using a
super capacitor (SC), designers can deliver the high current levels
needed for these short duration events and then recharge from the
battery between events. By reducing the current drawn from the
battery, this architecture offers users improved talk time and
longer battery life. It also allows the designer to reduce the
system footprint by
optimally sizing the battery and power circuitry to cover just the
average power consumption instead of peak levels
- A super capacitor can be used to store the required current and
deliver it quickly without draining the main
battery.
- Super capacitors recharge in seconds with >500k cycles and
store energy in an electrostatic field rather than a chemical state
like a battery
- Based on the energy storage mechanism the Super capacitors can be
classified into three basic types ; electrostatic double layer
capacitor (EDLC), electrochemical pseudocapacitor and hybrid
capacitors
- Common types
categorized by rated voltage, type, capacitance, packaging type and
case size / dimension. The most common values for capacitance are
0.22 F, 0.47 F and 1 F. super capacitors with capacitance up to 400
F are available. The rated voltage can be between 2.3 V and 11 V,
with the most common capacitors having a rated voltage of 5.5 V.
- The supercapacitor market is estimated to register a CAGR of
around 35.4% for the period 2015-2020 and is projected to reach
around
$4.2 billion by 2020. Consumer electronics and automotive segment
will be the highest revenue generating segments during this period
according to market research firms
- Electric Vehicles, whose shipments are estimated to reach 6.3
million units by 2022, is a huge opportunity for the super capacitor
manufacturers
- Important market segments are Industrial Automation Products,
Consumer Electronics Products, Power & Energy Products and
Transportation Products
- In the near
future, Super capacitors would make it possible to recharge a mobile
phone or laptop in just a few seconds. They would also allow
electric cars to travel similar
distances as petrol cars, but without the need to stop for lengthy
recharging breaks of typically six to eight hours. Instead, they
would recharge fully in the time it takes to fill
a regular car with petrol. An electric car could travel from New
York to Washington, D.C., without the need to recharge — but when it
did recharge for this operation to take just a few minutes to
perform
