Abstract

The invention provides a soft packing lithium ion battery and a method of producing the same. The electrical core of the lithium ion battery is provided with two electrode lugs, and the parts of the electrode lugs, which are exposed outside the electrical core of the lithium ion battery, meet the connection requirements. An adjusting belt with matchable shape and size is electrically connected with the parts of the electrode lugs, which are exposed outside the electrical core of the lithium ion battery, to form a new electrode lug. The soft packing lithium ion battery can better meet the requirement of the center distance between the electrode lugs, and the method of producing the soft packing lithium ion battery is easy and feasible and can be operated on the existing equipment of the battery manufacturer. The method of producing the soft packing lithium ion battery can be also used for modifying the structure of the prior soft packing lithium ion battery so as to ensure that the center distance between a positive electrode lug and a negative electrode lug of the manufactured or modified soft packing lithium ion battery is in a specified fluctuation range, thus the qualification rate of the electrical core of the lithium ion battery is improved, the materials in stock are reduced and the cost is lowered.
