The power type supercapacitor disclosed by the utility model has the advantages of large volumetric specific capacity, small equivalent series resistance, wide applicable temperature range and the like, and is a high-efficiency energy storage and energy conversion device.
Description
Technical field: the utility model relates to a kind of capacitor, relates in particular to a kind of ultracapacitor.
Background technology: well-known, the power density of ultracapacitor is far above lithium ion battery, and energy density is far above traditional capacitor, and its charge and discharge cycles number of times can reach more than 100,000 times, and the life-span reached more than 10 years; Have the charging interval short, charging and discharging currents is big, short time power output advantages of higher.Can be widely used in generation of electricity by new energy, new-energy automobile, intelligent grid, energy saving building, energy saving technology reduction of discharging and aviation, military affairs etc. needs the industry-by-industry of high power density and high-energy-density energy storage energy transducer.Yet though ultracapacitor has the high power density of traditional capacitor and the high-energy-density metric density advantage of storage battery concurrently, the operating voltage of single ultracapacitor receives the electrolyte decomposition voltage limit, and its operating voltage generally is no more than 1.5～3.5V.But though obtain the special voltage of total hectovolt through the serial connected super capacitor; But because the performance parameter of each single capacitor is inconsistent; Cause the breakdown inefficacy of individual capacitors because of voltage distribution is uneven easily, thereby cause the breakdown damage of whole capacitors, useful life is short.For this reason, must can amount control circuit come equalizing voltage through being provided with, not only power-supply system is complicated, thereby and series connection also can increase the reliability reduction that the system internal resistance causes peak power output and power-supply system; Therefore need that exploitation is a kind of to have reliability height, a ultracapacitor that power density is big badly.
Summary of the invention: in order to overcome the defective that exists in the prior art, the utility model aims to provide a kind of long service life, the little power type super capacitor of internal resistance.
To achieve these goals; The utility model adopts following technical scheme: it comprises metal shell, be fixed on this metal shell the positive pole of insulation with it, be fixed on the negative pole that is electrically connected with it on this metal shell, be encapsulated at least one cartridge units in the said metal shell, said cartridge units by anode strip, cathode sheets and be located at this anode strip and this cathode sheets between barrier film constitute; Separate by barrier film between the adjacent core subelement, be electrically connected through lead-out wire between the adjacent core subelement; Wherein, the anode strip that is positioned at uppermost cartridge units is connected, is positioned at nethermost cartridge units with positive electrical cathode sheets is connected with negative electricity.
Be connected in series through lead-out wire between the adjacent core subelement; Be connected in parallel through lead-out wire between the adjacent core subelement.
With prior art relatively, therefore the utility model can obtain higher operating voltage owing to adopted technique scheme, has overcome a plurality of ultracapacitors series connection and a series of defectives such as the internal resistance that brings is big, system complex and reliability are low; The utlity model has advantages such as simple in structure, that volume and capacity ratio is big, power density is high, equivalent series resistance is little, the Applicable temperature scope is wide.
