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.
In the above-mentioned “electronic” capacitors, the charge
transfer is performed by fast electrons, thereby creating
virtually instant rated capacitance value. In the BestCap
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

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.
by several varieties of supercapacitors, under short pulse
width conditions. It can also be seen from Figure 2, how well
