With economic continuous development, the energy, resource and environment etc. become the focal issue of society, find cleaning, can be again
Raw and resource-conserving the energy is that human society is very urgent and unusual difficult task.
Currently, in energy field, there are mainly three types of the energy storage devices of type：Battery, physical capacitor and electrochemical capacitor
Device (also referred to as ultracapacitor).Electrochemical capacitor was grown up in recent years between traditional physical capacitor and battery spy
Property between a kind of novel green energy storage device, have fast charging and discharging characteristic, power density greatly (be tens times of common batteries
More than), have extended cycle life (cycle-index is up to 100,000 times or more), and use temperature range is wide (between -40 DEG C~75 DEG C).Base
In these special performances, electrochemical capacitor has extraordinary application prospect.
