Description
Technical field: the utility model relates to a kind of capacitor, relates in particular to a kind of energy storage capacitor.
Background technology: well-known, in various electric energy storing devices, though the traditional capacitor power density is high, capacitance is little, energy density is low; Though the storage battery energy density is high, power density is low; Though ultracapacitor has the high power density of traditional capacitor and the high-energy-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,, cause the breakdown inefficacy of individual capacitors because of voltage distribution is uneven easily, thereby cause the breakdown damage of whole capacitors because the performance parameter of each single capacitor is inconsistent though obtain the special voltage of total hectovolt through the serial connected super capacitor.For this reason, can amount control circuit come equalizing voltage through being provided with usually, 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 a kind of high-efficiency energy-storage and energy transducer of exploitation badly with high working voltage.
Summary of the invention: in order to overcome the defective that exists in the prior art, the energy storage capacitor that the utility model aims to provide a kind of power density and capacitance is big, operating voltage is high.
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 in tantalum niobium anode bodies and ruthenium-oxide cathode in the said metal shell, be filled in the electrolyte in the metal shell; Tantalum niobium anode bodies is that n is individual, the ruthenium-oxide cathode is n+1, and ruthenium-oxide cathode and tantalum niobium anode bodies are spaced, and is separated by porous septum between the tantalum niobium anode bodies of each ruthenium-oxide cathode and vicinity; Each tantalum niobium anode bodies is parallel to positive pole through anode lead wire, and each ruthenium-oxide cathode is parallel to negative pole through cathode terminal; N is a natural number.
With prior art relatively, therefore the utility model can obtain to be higher than the operating voltage of 100V owing to adopted technique scheme, a series of defectives such as overcome that the internal resistance that a plurality of ultracapacitors series connection are brought is big, system complex and reliability are low; The utlity model has advantages such as simple in structure, that capacitance is big, energy density is big.
