Cylinder lithium battery

[0017] Figure 1-Figure 3 One embodiment of the invention is shown.

[0018] See Figure 1-Figure 3 , The first negative pole tab 22 and the second negative pole tab 23 are provided on the negative pole piece 21 , and the positive pole tab 12 is provided on the positive pole piece 11 . After the second negative tab 23 is set on the negative pole piece 21, compared with the state where only the first negative pole tab 22 is set on the negative pole piece 21, the internal resistance of a lithium battery of the same material and volume drops from 30mΩ to 19mΩ, that is, the About 1 / 3, the discharge rate of the lithium battery increases accordingly, which increases the output power of the lithium battery. Only one positive tab 12 is arranged on the positive pole piece 1, which occupies a small volume and has little impact on the capacity of the lithium battery, so that the capacity of the lithium battery of the same volume and material will not decrease significantly when the rat...
