Abstract

The invention relates to a formation capacity grading jig for a soft package lithium battery. A battery layering mechanism comprises a plurality of clamping plates; one faces of the clamping plates located at the two ends are connected with one face of a pressing plate and one end of a fixing and supporting mechanism correspondingly. Silica gel sheets are arranged on the other faces of the clamping plates and the two faces of each clamping plate located between the two ends, the clamping plates are connected through a connecting guide mechanism, and a self-locking transmission mechanism is connected to the pressing plate and drives the pressing plate to apply pressing force to the clamping plates or release pressure to the clamping plates. One end of the self-locking transmission mechanismis mounted at the other end of the fixing and supporting mechanism, and the other end is connected with the pressing plate. A compartment for accommodating the soft package lithium battery is formedbetween every two adjacent silica gel sheets in a compressed state. According to the formation capacity grading jig, a plurality of soft package lithium batteries can be clamped, the formation and capacity grading machining process of the soft package lithium batteries is completed, it is guaranteed that the soft package lithium batteries bear uniform and stable pressing force in the process, anddeformation is avoided.

Description

technical field [0001] The invention relates to a battery jig, in particular to a soft-packed lithium battery forming and containing jig. Background technique [0002] Soft pack lithium battery is a brand-new packaging form of lithium battery. Compared with metal shell packaging, soft pack battery has the characteristics of good safety performance, light weight, large capacity, small internal resistance and flexible design, and has great application space. However, the soft pack battery uses soft aluminum-plastic film as the battery shell. During the process of formation and capacity separation, due to the chemical reaction inside the film, the aluminum-plastic film will be deformed due to uneven force. Therefore, the battery is formed, During processes such as capacity separation, it is necessary to apply a uniform pressing force to the battery externally. Contents of the invention [0003] In order to solve the problem of deformation of the soft-pack lithium battery du...
