Hybrid/electric vehicle market is
expected to grow over the long
term due to higher government

•
As voltage is applied, charge accumulates on the electrode surfaces. Ions in the electrolyte solution
diffuse across the separator into the pores of the electrode of opposite charge. Thus, a double-layer
of charge is produced at each electrode.
• In ultracapacitors, charge separation distance is determined by the size of the ions in the
electrolyte, which are attracted to the charged electrode. This charge separation is much smaller
than can be accomplished using conventional dilectric materials.
The combination of enormous surface area
and extremely small charge separation
gives the ultracapacitor its outstanding
capacitance relative to conventional capacitors

acceleration.
TÍTULO DEL PATRÓN
Ultracapacitor technology is ideally suited to REGENERATIVE BRAKING
because:
ü They deliver many times more power for weight than lithium-ion
batteries.
ü They have efficiencies of up to 98%.
ü They are tolerant of high temperatures.
ü They charge almost instantly.
ü They are one of the cheapest technologies available for power discharges
below 15 secs.
It’s projected that as many as half of new cars
will be fitted with these systems by 2022.

•
Batteries perform poorly at low temperatures and the high temperatures common in
engine compartments also impair battery performance, shorten battery life and can
create serious safety hazards.

It is demonstrated that an integrated system combining batteries with ultracapacitors
dramatically improve braking energy recuperation efficiency and eliminate the need
for battery over-sizing, reducing the weight and cost of the entire system.

The ultra capacitor market has grown through application to consumer electronics. The most
typical case is mobile phone applications such as memories and time clocks. Based on these
applications, the global ultra capacitor market recorded 480 billion won in 2011.

future, reaching 840 billion won in 2015 and 1 trillion 250 billion won in 2020 at the annual
growth rate of 11.3%.
The ultra-small and small product
(less than 1F) markets are expected
to grow slightly, but the medium and
large product (more than 1F)
markets will grow. It is
also expected that the ultra-large
product market (more than 1000F)
will grow rapidly especially in the
field of transportation.
