なくなるという問題があった。In a battery using a positive electrode case with such hardness, the plating becomes soft due to contact with the sealing mold during sealing, and as shown in Figure 1, flakes of N1 plating occur at the upper end (inlet) of the positive electrode case 71. If it becomes loose and comes off, or if local pressure is applied to the side of the positive electrode case (section B in Figure 1) from the outside and scratches occur, N1 plating powder in the form of cutting chips (Figure 2) c') occurs and adheres between the positive electrode case 1 and the sealing plate 2, causing an external short circuit in the battery, causing capacity consumption and capacity deterioration. In addition, after inserting the battery into the device, Ni plating powder may be attached to the device's wiring or
If it adheres to a substrate or the like, there is a problem that the device will not operate normally.

が発生している。■ If the N1 plating hardness is HV200~400, use this N
In the range of e-plating hardness, 23% of defects occur due to pari formation in the Ni plating (occurs in the area shown in Figure 1), the rate of capacity deterioration of the battery itself is 1.2%, and the rate of deterioration of the battery's capacity is 1.2%, (In the case of this example, an electronic wristwatch was used) The incidence of substrate function-reduced products was 0.32%. This hardness range is N
1 plating powder is likely to be generated, and if N-plating powder C' in the form of cutting dust adheres between the positive electrode case and the sealing plate as shown in Figure 2, the positive electrode side and negative electrode side of the battery This can lead to direct conduction between the two sides, resulting in a short circuit and a decrease in the capacity of the battery itself. In addition, if T1 plating adheres to the wiring or circuit board of an appliance (electronic watch, etc.), it will lead to a decline in the functionality of the wiring or circuit board, causing the problem that the appliance itself will no longer function properly. .

In the range of i-plating hardness, the defects due to the generation of pari in the Ni plating are 0% under the conditions shown in Figure 1, and the rate of occurrence of products with inferior capacity of the battery itself and the occurrence of loss of function of the board of the device are both 0%. It becomes. As mentioned above, the purpose of eliminating the external short circuit of the battery and the functional deterioration of the wiring, board, etc. of the device into which the battery is inserted due to the occurrence of N1 failure has been fully achieved. The Ni plating hardness in this example is
The component ratio of the plating solution is NiSO4:N C1□:H,
