Abstract

The invention relates to a fixture for forming and containing a soft-packed lithium battery. The battery layering mechanism includes a plurality of clamping plates. And the two sides of each clamping plate located between the two ends are provided with silica gel sheets, and the clamping plates are connected by a connecting guide mechanism, and the pressing plate is connected with a self-locking transmission mechanism, which drives the pressing plate to each clamping plate. Apply compressive force or release pressure; one end of the self-locking transmission mechanism is installed on the other end of the fixed support mechanism, and the other end is connected to the pressing plate; a space for accommodating the soft-packed lithium battery is formed between two adjacent silica gel sheets in a compressed state. compartment. The present invention can clamp a plurality of soft-pack lithium batteries, complete the process of formation and volume separation, and ensure that the soft-pack lithium batteries are subjected to uniform and stable pressing force during the process, and the formation and volume separation fixture will not be deformed.

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...
