A large-capacity high-power polymer lithium ion battery comprises a positive-electrode piece, a diaphragm bag, a negative-electrode piece, a positive-electrode double cell, a positive-electrode single cell, a negative-electrode double cell and a negative-electrode single cell. According to the large-capacity high-power polymer lithium ion battery, a short circuit caused by the contact of the positive-electrode piece and the negative-electrode piece of the battery is avoided, manual operation in a battery assembling process is reduced, affects from human factors on the quality of the battery is reduced, producing efficiency and product quality are improved, producing cost is reduced, and service life and safety performance of the battery are guaranteed. Mechanized production of battery assembling is provided with supports of the process basic theory, and equipment manufacturing of lithium batteries in future is provided with a basis.
