Technical field
The present invention relates to a kind of electrode material electric conductivity test device, in particular it relates to a kind of powdered electricity Pole material electric conductivity simulating test device.
Background technology
With the scientific and technological progress in epoch, new-energy automobile has turned into auto manufacturing's developing direction important from now on.Existing Having under technical conditions, the supporting electrokinetic cell of new-energy automobile mainly has lead-acid accumulator, lead carbon battery or lithium battery, these three The electrokinetic cell both positive and negative polarity of type is powdered electrode material product.The performance quality of electrokinetic cell depends primarily on powder used Last shape electrode material electrical conductivity height, the industry generally carry out conductivity measurement to accomplish to quantify test using four probe method. Before this method test, powdered electrode material is first pressed into strip by electrode size to be measured, then re-sinters shaping.Prior art Although enforcement difficulty is little, operability is also very strong, can realize the conductivity measurement of powdered electrode material.But power The electrode of battery actual use is in the powder electrode for compressing shape, is not the electrode of sinter molding, although both powder used Electrode material is identical, but structure type is completely different, so four probe method is not suitable for accurate measurement powdered electrode.
The content of the invention
The problem of being not suitable for accurate measurement powder electrode test present invention is generally directed to prior art four probe method, proposes one Kind powdered electrode material electric conductivity simulating test device, the apparatus structure is simple, makes easy, simple operation, due to test Condition is similar to actual service conditions, and test result is accurate, reliable.
The present invention is achieved through the following technical solutions technical goal.
Powdered electrode material electric conductivity simulating test device, it includes outer cylinder body, inner barrel, movable terminal, cushion block, powder Last shape electrode material, fixing terminal, wire and tester.It is theed improvement is that:The inner barrel axially penetrates through outer cylinder body simultaneously Exposed both ends, one end of inner barrel plug dress fixing terminal are fixedly connected with outer cylinder body, and the other end disposes the inner barrel of movable terminal With outer cylinder body fit.The powdered electrode material is filled in the inner chamber of inner barrel stage casing, with the activity being placed in inner barrel Terminal promotes cushion block compacted powder shape electrode material.The fixing terminal is connected with the overhanging end of movable terminal by wire, two Tester is concatenated between root wire and forms simulation test loop.
As further improvement project, the outer cylinder body and inner barrel are manufactured with insulating materials, preferably plastic manufacturing.Activity Terminal, fixing terminal and cushion block are pure red copper matter product.
As further improvement project, the movable terminal is adjustable diameter and screw adjusting knot with respect to the axial displacement structure of inner barrel Structure.
The present invention compared with prior art, has the positive effect that:
1st, telescopic test device is simple in construction, makes easy, easy to use;
2nd, pure physical measurement, low is required to test condition, is easy to use in production scene;
3rd, powdered electrode material, which is injected into inner barrel, is compacted, such a testing conductivity under simulation status, is easy to get to connecing The electrical conductivity relative value of nearly practical application, because the data validity for obtaining electrode used therein material electric conductivity is strong, be advantageous to accelerate Battery new-product development progress.
