The side of the positive electrode guard plate 4 facing the battery cell (as shown in fig. 7), the side of the negative electrode guard plate 7 facing the battery cell (as shown in fig. 8) and the two sides of the middle partition plate 5 (as shown in fig. 9 and 10) are respectively provided with a positioning groove 30 matched with the end part of the battery cell, and the side wall of the positioning groove 30 is provided with a notch 31 for the nickel strap 2 to pass through.

When the cell unit comprises more than 2 parallel groups 1 of cells, a middle partition board 5 is arranged between every two adjacent parallel groups 1 of cells in the cell unit, and through holes for screws 8 to pass through are formed in the middle partition board 5. As for the number of the parallel battery cells 1 included in the battery cell unit and the number of the battery cells included in each parallel battery cell 1 should be determined according to the capacity requirement of the battery. In addition, the positioning grooves 30 may be provided only in the portions of the positive electrode protection plate 4, the negative electrode protection plate 7, and the separator 5.

Further, the battery also comprises a printed board 10 which is positioned at one side of the battery cell and connected with the nickel strap 2, and the anode guard board 4 and the cathode guard board 7 are respectively connected with the printed board 10 through printed board fastening screws 11, as shown in fig. 11 to 13. The nickel strap 2 is provided with a lead-out portion welded to the printed board 10, and the lead-out portion of the nickel strap 2 is bent and welded to the printed board 10 (as shown in fig. 16). Further, it is preferable that the printed board 10 is provided with projections 34 at both ends, and the positive electrode protection plate 4 and the negative electrode protection plate 7 are provided with grooves 33 respectively which are fitted with the projections 34 at both ends of the printed board 10. Specifically, the positive electrode guard plate 4 and the negative electrode guard plate 7 are further provided with screw holes for fixing the printed board 10, and the printed board 10 is fixed to the side face of the battery body by the printed board fastening screws 11, so that the printed board 10 can be prevented from moving or separating from the battery body, and breakage of the lead-out portion of the nickel strap 2 welded to the printed board 10 can be avoided.
It should be noted that, in other embodiments of the present invention, the printed board 10 may be fixed to the positive electrode protection plate 4 and the negative electrode protection plate 7 in other manners. For example, the positive electrode guard plate 4 and the negative electrode guard plate 7 are in snap connection with the printed board 10.

The tensile strength of the welding reinforcing spring piece 6 is far higher than that of the nickel strap 2. After assembly, the two spring plate parts of the welding reinforcement spring plate 6 are respectively abutted against the nickel strips 2 of the adjacent 'parallel battery cell group 1', and are conducted, and the reliability of series connection conduction can be ensured due to the elastic characteristic of the welding reinforcement spring plate 6.

When the leading-out parts of the nickel strap 2 of the positive electrode and the negative electrode are broken accidentally, the standby wire 13 can ensure the conduction between the nickel strap 2 and the printed board 10, thereby ensuring the reliability of the battery. The positive electrode plate 4 and the negative electrode plate 7 are preferably provided with spare wire grooves 29 for accommodating spare wires 13 and solder packages 35 thereof, respectively.
