240 and the first conductive wire member 400 have a space therebetween into which a first support member 410 is inserted.

The first conductive wire member 400 may be coupled to the first support member 410 by screw threads. Specifically, a screw thread formed on the outer surface of the first conductive wire member 400 and a screw thread formed on the inner surface of the first support member 410 may engage with each other.

In addition, the first support member 410 may be coupled to the first through hole 240 by screw threads. Specifically, a screw thread formed on all or part of the outer surface of the first support member 410 and a screw thread formed on all or part of the inner surface of the first through hole 240 may engage with each other.

Between the first support member 410 and the first through hole 240, a sealing member (not shown) may be inserted therebetween to seal the inner space from the outside.

The analysis device 100 may include a second conductive wire member 600 penetrating another side wall of the body member 200 and being partially inserted into the inner space.

The second conductive wire member 600 may provide current and/or voltage needed in charging and discharging the battery cell, and may include a conductive material. Specifically, the second conductive wire member 600 may include a conductive metal, and may have rigidity sufficient to maintain its shape even when a predetermined pressure is applied.

Hereinafter, the connection relationship between the second conductive wire member 600 and the body member 200 will be described in detail.

The body member 200 may include a second through hole 250 formed through another side wall with a diameter wider than a diameter of the second conductive wire member 600. The second conductive wire member 600 is inserted into the inner space through the second through hole 250.

The second through hole 250 and the second conductive wire member 600 may have a space therebetween into which a second support member 610 is inserted.

The second conductive wire member 600 may be coupled to the second support member 610 by screw threads. Specifically, a screw thread formed on the outer surface of the second conductive wire member 600 and a screw thread formed on the inner surface of the second support member 610 may engage with each other.

In addition, the second support member 610 may be coupled to the second through hole 250 by screw threads. Specifically, a screw thread formed on all or part of the outer surface of the second support member 610 and a screw thread formed on all or part of the inner surface of the second through hole 250 may engage with each other.

Between the second support member 610 and the second through hole 250, a sealing member (not shown) may be inserted to seal the inner space from the outside.

The first conductive wire member 400 and the second conductive wire member 600 may be installed to have the same central axis. The battery cell may be installed between the first conductive wire member 400 and the second conductive wire member 600, and a predetermined pressure is applied to the battery cell. Here, when the central axis of the first conductive wire member 400 and the central axis of the second conductive wire member 600 are not placed on the same line, the battery cell may not be properly loaded or pressure may be unevenly applied to the battery cell.

The analysis device 100 may include a first mounting member 500 including a first substrate having a shape of a plate and a predetermined area. The first mounting member 500 may be coupled to an end of the first conductive wire member 400 to support one surface of the battery cell.

The analysis device 100 may include a second mounting member 700 including a second substrate having a shape of a plate and a predetermined area. The second mounting member 700 may be coupled to an end of the second conductive wire member 600 to support another surface of the battery cell.

The battery cell may be loaded between the first mounting member 500 and the second mounting member 700.

FIG. 5 shows the first mounting member 500 and the second mounting member 700. In FIG. 5, the second mounting member 700 is illustrated in a first embodiment. FIG. 6 shows a battery cell loaded between the first mounting member 500 and the second mounting member 700.

The first substrate 510 may have one surface connected to one end of the first conductive wire member 400. A method of connecting the first substrate 510 with the first conductive wire member 400 is not particularly limited. The first substrate 510 may be connected with the first conductive wire member 400 by welding, thread screwing, or the like.

The first mounting member 500 may further include a first current collecting member 520 disposed on another surface of the first substrate 510 and having the same or smaller area than the first substrate 510.

The first current collecting member 520 may be brought into direct contact with the battery cell so as to apply the current and/or voltage provided from the first conductive wire member 400 to the battery cell and collect electrons generated from the battery cell.

The first current collecting member 520 may include a platinum mesh (Pt mesh) or the like. As described above, because the first current collecting member 520 is brought into direct contact with the battery cell, more stable current collection is possible.

FIG. 7 shows a battery cell having a smaller area than that of the first substrate 510 is loaded. The first substrate 510 has installed thereon a first current collecting member 520 having an area equal to that of the battery cell, and has installed thereon a spacer 530 on the remaining area of the first substrate 510.

FIG. 8 shows a battery cell having an area equal to that of the first substrate 510 is loaded. The first substrate 510 has installed thereon a first current collecting member 520 having an area equal to that of the battery cell, and the battery cell is loaded thereon. The battery cell may have a structure in which a positive electrode layer, an electrolyte layer, and a negative electrode layer are stacked in this order. The positive electrode layer and the negative electrode layer may be brought into contact with the first current collecting member 520 and a second current collecting member 740, and the electrolyte layer is provided therebetween.

Because the analysis device 100 is configured to analyze the cross section of the battery cell, the battery cell may be loaded between the first mounting member 500 and the second mounting member 700 with the cross section thereof facing the cover member 300.
