In the test process, the slurry is filled from the slurry filling opening and overflows from the slurry overflowing opening, an impedance test instrument continuously tests the impedance of the slurry when the slurry passes through the pool body, and then, the consistency of the slurry can be judged through analyzing the consistency of the data. The device has the advantages that the structure is simple, the operation is convenient, and the usability of measuring results is high.
Description
Technical field
The utility model relates to technical field of lithium-ion battery, is specifically related to the conforming proving installation of pulp of lithium ion battery, especially directly the proving installation of reaction paste consistency of performance.
Background technology
Because lithium ion battery other batteries relatively has the incomparable superior function and the diversity of sharp processing, obtained application more and more widely at present, so the technology of lithium ion battery is studied more and more also.
For important processing link of lithium ion battery---the configuration of slurry, industry is more and more paid attention to from the technician.The test of slurry preparing process, slurry store method and sizing agent consistency etc. all becomes the emphasis of research, because the consistance of slurry has an immense impact on to the following process (the most direct painting process) and the performance of finished product battery, as: the pole piece surface appearance is poor, capacity of battery, circulation, security performance etc.
Test conventional method to sizing agent consistency has at present: adopt the particle size of fineness gauge testing size, the viscosity that adopts the viscosity meter testing size, electron-microscope scanning SEM etc., above method of testing all is to adopt static test, can only feed back slurry situation at a time.In fact in the battery production process, the state of slurry is continual variation, so existing conventional static test can't satisfy the high-quality requirement of present battery production.
The utility model content
Technical problem to be solved in the utility model has provided a kind of size performance consistency test device of new structure, this device can be carried out the homogeneity of on-line testing slurry, the dynamic response slurry is at the different conditions of different time points, thereby provides foundation for the production of lithium battery.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
The conforming device of a kind of measurement size performance, comprise the pond body that is used to hold slurry, have slurry inlet and slurry spillway on the body of pond, the testing impedance contact block that can measure the slurry resistance value also is installed on the body inwall of pond, described testing impedance piece is connected with the external impedance testing apparatus.
Be the performance of the slurry in the measuring cell body more accurately, be separately installed with the testing impedance contact block on the pond body inwall near slurry inlet and slurry spillway, the testing impedance contact block is a derby.Be convenient to the situation that operating personnel understand slurry in the body of pond simultaneously, be equipped with transparent lid at body top, described pond.
The utility model has following remarkable result compared to existing technology:
1, the utility model proving installation is simple in structure, and is cheap for manufacturing cost, can replace existing expensive testing tool, practical.
2, this proving installation can be realized on-line testing, than before static test realized great leap, this proving installation has been realized follow-on test, in time reflect the different conditions of slurry at different time, for subsequent production provides foundation, stopped because slurry in use changes quality even the safety problem that causes battery, this proving installation is that battery satisfies high-end demand and provides safeguard.
Description of drawings
Accompanying drawing 1 is the utility model perspective view.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing.
Referring to accompanying drawing 1, the conforming device of a kind of measurement size performance, this device can be tested the performance that is positioned over the fluid in the body of device pond, and present embodiment describes at the impedance behavior test that holds the lithium battery anode and cathode slurry in the body of pond.
The device of present embodiment comprises the pond body 1 that is used to hold cell size, and body top, pond is equipped with transparent lid 4, and the state that transparent cover body is convenient to the slurry that holds in operating personnel's claire body is set.Body top, pond one end has slurry inlet 2, and body top, the pond other end is provided with slurry spillway 3, and slurry inlet 2 is communicated with the cell size flow in pipes, and pond somaplasm material spillway overflows pipeline with slurry and is communicated with.
Be real-time, the dynamic resistance value that enters the cell size in the body of pond that detects exactly, the testing impedance contact block 5 that can measure the slurry resistance value also is installed on the body inwall of pond, and the present embodiment proving installation is installed near making on the pond body inwall of slurry inlet 2 and slurry spillway 3 that test is more accurate the testing impedance piece.The testing impedance contact block is selected common derby for use, and at present general test test pencil contact area is too little, so adopt derby to replace existing general testing impedance test pencil as testing impedance contact block of the present utility model.The testing impedance contact block is connected with the external impedance testing apparatus.The slurry resistance value that different materials, proportioning can be set on the external impedance testing apparatus is done reference, by the consistance of analysis detecting data, can infer the consistance of slurry then.
In the process that slurry is using, shifting, slurry injects the pond body 1 that has cavity from the slurry flow in pipes by slurry inlet 2, when Chi Tizhong filled up slurry (fixedly slurry volume), slurry entered subsequent production processing from slurry spillway 3 and uses; When filling up, passes through in slurry testing impedance contact block and testing impedance equipment, the impedance magnitude of dynamic testing size, go out the conforming situation of slurry by impedance and response fluctuation thereof, thereby realize its consistance of on-line testing of slurry, be convenient in time pinpoint the problems, for subsequent production provides guidance, thereby stopped battery because the sizing agent consistency difference causes the quality problems even the safety problem of battery.
The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.For example can change the performance test of the test block that is installed on the body inwall of pond with the different slurries that inject in the adaptation pool body.That is to say that under the prerequisite that does not break away from the present utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
