[0002] Currently, for alkaline zinc-manganese batteries, the number of positive electrode rings inside the steel casing is often 2-4. This inevitably results in gaps between the positive electrode rings, which means an increase in internal resistance and thus affects the battery's electrical performance. Therefore, reducing the gaps between the positive electrode rings can effectively improve the battery's performance. By testing the gaps between the positive electrode rings and the corresponding intercalation pressure, the required intercalation pressure for the production line can be accurately determined, enabling precise control of the intercalation pressure and breaking through technical bottlenecks.

[0018] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0019] As shown in Figure 1, this utility model discloses a test device for the gap of the positive electrode ring of an alkaline manganese battery, including a base plate 1, a support column 2 is provided on the upper side of the base plate 1, a test platform 13 is fixed on the support column 2, a placement table 10 is provided on the upper side of the test platform 13, a pressure sensor 11 is provided on the lower side of the placement table 10, the pressure sensor 11 is connected to a pressure digital display screen 12, and a test pressure head 9 and a distance digital display table 8 for displaying the extrusion stroke are provided on the upper side of the placement table 10.

[0020] Furthermore, a support frame 14 fixed to the pillar 2 is also provided on the lower side of the test platform 13.

[0021] Furthermore, a track column 6 is provided on the upper side of the support column 2, and a slider 5 is slidably provided on the track column 6.

[0022] Furthermore, an extension arm 7 is fixedly connected to the slider 5, and the test pressure head 9 and the distance digital display 8 are provided on the side of the extension arm 7 away from the track column 6.

[0023] Furthermore, a motor 3 is also provided on the support column 2, and a threaded shaft 4 is connected to the upper side of the motor 3.

[0024] Furthermore, the threaded shaft 4 passes through and is threadedly connected to the slider 5.

[0025] Specifically, the battery is placed on the placement platform 10, and then the motor 3 is started, which drives the threaded shaft 4 to rotate, which in turn drives the slider 5 to move down, which in turn causes the extension arm 7 and the test head 9 to move down, squeezing the positive electrode ring. At the same time, the values ​​of the distance digital display 8 and the pressure digital display screen 12 are observed.

[0026] The specific testing method is as follows:

[0027] The test simulates the embedding of the positive electrode ring into the steel shell under different pressures, and records the corresponding embedding depth of the positive electrode ring. The prerequisite for the test is that no ring breakage or other phenomena occur during the embedding process, so as not to affect the test results.

[0028] As the test pressure increases until there is no fluctuation on the digital display 8, an X-ray machine is used to inspect the condition of the positive electrode ring inside the battery, and the gap between the positive electrode rings is illustrated.

[0029] By simulating the pressure required for the positive electrode ring to be embedded in the steel shell in this way, and characterizing the way the gap between the positive electrode rings tends to 0, the pressure required for the production line and the stroke required for the ring embedding equipment can be effectively evaluated.
