Abstract
The utility model provides a hydrogen storage alloy negative pole piece device for testing, comprising a nickel belt, a hydrogen storage alloy negative pole piece and foamed nickel, wherein the hydrogen storage alloy negative pole piece is directly hung in a tail groove of the nickel belt; a battery membrane is arranged on the outer layer of the hydrogen storage alloy negative pole piece; the foamed nickel is arranged outside the battery membrane. The hydrogen storage alloy negative pole piece device for testing is simple in operation; as the battery membrane is arranged on the outer layer of the hydrogen storage alloy negative pole piece, the phenomenon that alloy powder falls off from the foamed nickel, caused by the fact that the circulation times of the hydrogen storage alloy negative pole piece are too much, the soaking time in alkaline liquor is too long or the reaction is too violent can be solved, and no unfavourable influence is caused on the performance testing of hydrogen storage alloy.
Description
Technical field
The utility model relates to test hydrogen storage alloy negative sheet, specifically a kind of device of testing with hydrogen storage alloy negative sheet.
Background technology
At present, device for the negative plate of hydrogen storage alloy electrochemical performance test is fairly simple, the general device that respectively stacks a nickel foam at the upper and lower of negative plate that adopts, this device is no problem during for the volume test of hydrogen bearing alloy, but when when it come to the testing time, the longer electrochemical kinetics that cyclical stability is tested and reaction is more violent was tested, can because negative plate cycle-index too much and in alkali lye long soaking time or reaction too violent, and the phenomenon that generation hydrogen storing alloy powder comes off from nickel foam, this is disadvantageous to hydrogen storage alloy performance test.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provide a kind of simple in structure, can solve hydrogen storage alloy negative sheet cycle-index too much, the device of hydrogen storage alloy negative sheet for long soaking time or the too violent and test that comes off from nickel foam of reaction in alkali lye.
The utility model solves the technical scheme that its technical problem adopts:
A kind of device of testing with hydrogen storage alloy negative sheet, comprise nickel strap, hydrogen storage alloy negative sheet, nickel foam, described hydrogen storage alloy negative sheet is directly mounted in nickel strap end groove, its innovative point is, described hydrogen storage alloy negative sheet skin is provided with battery diaphragm, and described battery diaphragm is provided with nickel foam outward.
Described hydrogen storage alloy negative sheet and battery diaphragm adopt carbonaceous conductive glue to carry out bonding.
A kind of test with the device of hydrogen storage alloy negative sheet compared with prior art of the present utility model, the beneficial effect producing is:
The utility model is simple in structure, hydrogen storage alloy negative sheet be provided with outward battery diaphragm can solve hydrogen storage alloy negative sheet cycle-index too much, long soaking time or the too violent and phenomenon that causes alloyed powder to come off from nickel foam of reaction in alkali lye, and can not have a negative impact to the performance test of hydrogen bearing alloy.
Accompanying drawing explanation
Accompanying drawing 1 is for having adopted negative plate structure of the present utility model and test schematic diagram.
Accompanying drawing 2 is traditional negative plate structure and test schematic diagram that does not add battery diaphragm.
In figure, 1, nickel strap, 2, hydrogen storage alloy negative sheet, 3, nickel foam, 4, battery diaphragm.
Embodiment
Below in conjunction with 1,2 pairs of a kind of tests with the device of hydrogen storage alloy negative sheet of the present utility model of accompanying drawing, be described in detail below.
As shown in Figure 2, generally, hydrogen storage alloy negative sheet 2 is first fixed in nickel strap 1 groove, then directly at hydrogen storage alloy negative sheet 2 skins, is provided with two nickel foam 3.In test process, this device can because of the cycle-index of hydrogen storage alloy negative sheet 2 too much, in alkali lye, long soaking time or test reaction too acutely cause alloyed powder to see through nickel foam 3 to enter testing apparatus, the performance test of hydrogen bearing alloy is had a negative impact.
As shown in Figure 1, hydrogen storage alloy negative sheet 2 of the present utility model is first fixed in nickel strap 1 groove, then at hydrogen storage alloy negative sheet 2 skins, be provided with one deck battery diaphragm 4, at battery diaphragm 4 skins, nickel foam 3 is set again subsequently, in test process, this device can not have a negative impact to the performance test of hydrogen bearing alloy.
A kind of test of the present utility model uses the device processing and fabricating of hydrogen storage alloy negative sheet simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characterictic described in specification, be the known technology of those skilled in the art.
Claims (2)
