Embodiment 1
[0090] The single battery includes a casing and a pole core located in the casing. The two surfaces of the casing are respectively provided with electrode terminals that are electrically connected to the pole core and extend out of the casing for drawing current. The electrode terminals on each surface are 2 pieces; there are lugs on the pole core, and the electrode terminals are electrically connected to the pole core through the lugs; L1 is the width of the lug, L2 is the width of the pole piece, L2 / L1=15, L1=40mm, the mark of the single battery for S1.
Embodiment 2
[0092] Compared with Example 1, the difference is that L2 / L1=20, L1=55mm, and the single battery is marked as S2.
Embodiment 3
[0094] Compared with Example 1, the difference is that L2 / L1=30, L1=50mm, and the single battery is marked as S3.
