Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to an open-cell drying and transport box. Background Technology

[0002] During battery manufacturing, to prevent the core from absorbing water, the storage environment of the cells after grooving needs to be strictly controlled for moisture content. If there is too much moisture, the electrolyte will react with the moisture during the subsequent manufacturing process to produce lithium salts. At the same time, too much moisture inside the battery will also generate a large amount of gas during charging and discharging, causing the internal pressure of the battery to increase, and may even cause the explosion-proof valve to open during the manufacturing process.

[0003] In the existing technology, existing drying ovens generally do not have battery racks inside, so the batteries cannot be fixed inside. They also usually require external power to maintain the dryness inside the oven, which is inconvenient for transportation. Furthermore, the internal space of existing drying ovens is small, making them unsuitable for transporting large quantities of grooved battery cells. Therefore, we propose an open-type battery cell drying and transportation box to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing drying ovens, which generally lack internal battery racks, making it impossible to secure batteries inside. Furthermore, they typically require external power to maintain dryness within the oven, which is inconvenient for transportation. Additionally, the limited internal space of existing drying ovens makes them unsuitable for transporting large quantities of grooved battery cells. Therefore, this invention proposes an open-type battery cell drying and transport box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An open-cell drying transport box includes a box body, and the transport box further includes:

[0007] The box door is hinged to the front side of the box body and has an observation window.
