Positive tab of polymer lithium ion battery

The utility model discloses a positive tab of a polymer lithium ion battery. The positive tab comprises an aluminum-nickel composite strip sheet body and an insulation rubber block arranged in the middle or at the upper end of the aluminum-nickel composite strip sheet body, wherein the insulation rubber block wraps the aluminum-nickel composite strip sheet body. According to the positive tab of the polymer lithium ion battery, disclosed by the utility model, an aluminum-nickel composite strip forms a tab body, thus the trouble of laser welding when the positive tab is produced in the prior art is prevented, a manufacturing process of the positive tab is simplified, the production efficiency of the polymer lithium ion battery is favorably improved, the bending resisting times of the positive tab is increased by 2.5 times, and the service life is prolonged.
