Description

Technical Field

[0001] This utility model relates to the field of battery cell support technology, and in particular to a soft-pack battery cell support. Background Technology

[0002] Soft-pack batteries are thin lithium-ion batteries that use a flexible aluminum-plastic composite outer shell and lithium-ion electrolyte. They are characterized by their light weight, small size, and good safety performance, and are widely used in portable electronic products, electric vehicles, energy storage devices, and other fields. The positive and negative electrode tabs of soft-pack batteries are made of thin metal sheets, making the tab structure relatively fragile and prone to tearing during bending. The bottom corners of soft-pack batteries are also more prominent, making them susceptible to friction damage and leakage. The surface of the soft-pack battery is made of aluminum-plastic packaging, which is easily scratched during installation into battery modules, affecting the lifespan of the battery modules. To protect the soft-pack batteries, cell brackets are provided for support during the connection and fixing process. However, most existing cell brackets install individual soft-pack batteries in a single bracket and then arrange them in series or parallel to form a group. This method of installing a single cell in a single bracket results in many repetitive processes, which can affect production efficiency. Furthermore, misalignment can easily occur when stacking cell brackets, further reducing production efficiency. Utility Model Content
