Background technology
The Experimental cell device is a device commonly used in a kind of electrochemical property test.In the research of battery material, often use the Experimental cell device that positive electrode, negative material, diaphragm material and electrolytic solution are assembled into Experimental cell, measure all performances of battery material, as the conductivity of charge/discharge capacity, charge and discharge cycles, solid electrolyte etc.
Use the battery (as lithium ion battery) of nonaqueous electrolytic solution must under dry environment, carry out charge and discharge and measurement.In the past, this class battery need clamp barrier film with electrode slice in exsiccator or dry glove box and bubble goes in the electrolytic solution to constitute battery, drew lead then and measured.In whole measuring process, the battery that is made of positive and negative plate, barrier film and electrolytic solution must remain in exsiccator or the glove box, and testing tool must be put together with exsiccator or glove box during measurement, brings many inconvenience to operation.In order to address this problem, people have proposed some solutions.The one, be assembled into button cell, the 2nd, adopt dismountable Experimental cell device to assemble Experimental cell.Button cell and these adopt Experimental cells of Experimental cell devices assembling to finish the back in the battery assembling and take out from exsiccator or glove box and measures, the problem that surveying instrument must be put together with exsiccator or glove box when having solved measurement thus.But the assembling of button cell needs special equipment, and the dismounting of battery is very inconvenient.(as: patent No. is 99227657.8 to the Experimental cell device that exists, and name is called: the Chinese utility model patent of " electrochemical measurement test cell device " at present.) then there is poor, the leakage easily of sealing, or problems such as corrosion stability is poor, easy damage.
Summary of the invention
The purpose of this utility model is to provide a kind of good airproof performance, Experimental cell device that corrosion stability is good for the battery (as lithium ion battery) that uses nonaqueous electrolytic solution.
The utility model comprises: battery case hold concurrently first external electrode, cover plate hold concurrently second external electrode, insulator seal ring, dead ring, conduction pressure head, power spring.Insulator seal ring is clipped in cover plate and holds concurrently between second external electrode and double first external electrode of battery case; There is arc groove cover plate and battery case and insulator seal ring contact position; Dead ring is near the battery case inwall; The conduction pressure head is arranged in battery case; Power spring between cover plate is held concurrently second external electrode and conduction pressure head, cuff contacts on the conduction pressure head and with double second external electrode of cover plate; Between the bottom of battery case and conduction pressure head, leave the space that is used to place mesuring battary.In addition, on the outside surface of double second external electrode of cover plate and double first external electrode of battery case, also conductive connector can be installed.
The Experimental cell device that the utility model is related, its shell external electrode of holding concurrently is made of metal material, has good electrical conductivity with the external electrode that guarantees Experimental cell.Insulator seal ring is made of whippy electrically insulating material, and there is arc groove cover plate and battery case and insulator seal ring contact position, to guarantee air tight, the no leakage of Experimental cell, guarantees the not short circuit of positive and negative electrode of Experimental cell.The conduction pressure head and the power spring that connect battery electrode and external electrode are made of metal material, and make the power spring lock ring on the conduction pressure head, and to guarantee that battery electrode closely contacts with external electrode, electric current is unimpeded.Dead ring electricity consumption insulating material in the battery case is made, and causes short circuit to guarantee that the conduction pressure head can directly not contact with the battery case inwall with power spring.Cover plate the hold concurrently conductive connector of the first external electrode outside surface of second external electrode and battery case of holding concurrently is made of metal material, guaranteeing that electric current is unimpeded, and conveniently is connected with instrument and measures.Six indispensable parts of Experimental cell device (battery case hold concurrently first external electrode, cover plate hold concurrently second external electrode, insulator seal ring, dead ring, conduction pressure head, power spring) all adopt the material that electrolytic solution is had good stability and corrosion resistance, with the stability that guarantees Experimental cell and the durability of Experimental cell device.
The utility model is simple in structure, cost is lower, easy to use, unpick and wash easily, good airproof performance, corrosion stability is good, can prolonged and repeatedly use.
