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