Abstract

The embodiment of the invention provides an unformed battery, a preparation method of the battery and formation equipment, the unformed battery comprises an air bag and a battery main body connected with the air bag, and the air bag is provided with reinforcing ribs. Due to the fact that the air bag is provided with the reinforcing ribs, the stress strength of the air bag is enhanced, in the formation process of the battery, the anti-pressure ability to the pressure of generated gas is enhanced, namely, the deformation degree of the air bag is reduced, the deformation direction of the air bag can be more regular, and then the possibility of generation of wrinkles or collapse is reduced.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to an unformed battery, a method for preparing the battery and a formation equipment. Background technique [0002] With the rapid development of new energy technology, battery technology, as an important new energy technology, has also developed rapidly and has been widely used in daily life. [0003] In battery technology, in order to improve the safety and flexibility of battery applications, batteries have appeared. Compared with batteries with metal casings, in the case of potential safety hazards, the batteries will only burst when there is a safety hazard, and it is not easy to explode. It has the advantages of light weight, large capacity, small internal resistance and flexible design. [0004] In the production process of the battery, the main body of the battery needs to be placed in the packaging case, and then the electrolyte solution is injected into the pa...
