The super capacitor has the advantages of high energy density and higher power density than a rechargeable battery, can be charged and discharged quickly, has a long service life, has very wide ranges of voltage and working temperature, and is a novel, efficient and practical energy storage device.
Description
Technical field
The invention belongs to capacitor technology field, be specifically related to a kind of ultracapacitor of Graphene electrodes.
Background technology
The novel batteries such as Li ion, NiMH can provide a reliable energy storage program, and widely use in a lot of field.As everyone knows, chemical cell is by electrochemical reaction, and produce faraday Charger transfer and store electric charge, useful life is shorter, and temperature influence is comparatively large, this is the difficulty adopting the designer of lead-acid battery (storage battery) to face too.Meanwhile, big current directly can affect the life-span of these batteries, and therefore, for some application requiring long-life, high reliability, these batteries based on chemical reaction just show all deficiencies.
The decisive factor affecting its capacity in ultracapacitor is electrode material.In existing ultracapacitor, electrode material mainly contains: active carbon series and transition metal oxide series.The material conductivity of active carbon series is poor, and the electrode equivalent series resistance as capacitor is large.And the specific area practical efficiency of this active carbon series is no more than 30%, electrolyte ion is difficult to enter.Transition metal oxide is used as electrode material and has good effect in the capacity improving ultracapacitor, but its cost is too high, cannot promote the use of.
Summary of the invention
Technical problem to be solved by this invention is, for above-mentioned deficiency of the prior art, to provide a kind of ultracapacitor of Graphene electrodes.This ultracapacitor has large and higher than the rechargeable battery power density advantage of energy density, and can fast charging and discharging, and long service life, has very wide voltage and operating temperature range, is a kind of novel, efficient, practical energy storing device.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ultracapacitor of Graphene electrodes, comprise shell, it is characterized in that, be provided with two Graphene electrodes parallel with side wall of outer shell in described shell, be filled with electrolyte between two described Graphene electrodes, between two described Graphene electrodes, be provided with barrier film, the end of described Graphene electrodes is provided with lead-in wire, and described lead-in wire passes shell and is connected with the pin be arranged at above shell.
The ultracapacitor of above-mentioned a kind of Graphene electrodes, described barrier film and Graphene electrodes be arranged in parallel.
The ultracapacitor of above-mentioned a kind of Graphene electrodes, described barrier film is positioned at the centre position of two Graphene electrodes.
The present invention compared with prior art has the following advantages:
1, ultracapacitor of the present invention has large and higher than the rechargeable battery power density advantage of energy density, and can fast charging and discharging, and long service life, has very wide voltage and operating temperature range.
2, ultracapacitor of the present invention is a kind of novel, efficient, practical energy storing device.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
