Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically a decentralized lithium battery drying device. Background Technology

[0002] Lithium-ion batteries are batteries whose electrochemical system contains lithium, including metallic lithium, lithium alloys, lithium ions, and lithium polymers. Lithium-ion batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. As an energy storage medium, lithium-ion batteries have a relatively stable structure, especially their internal components, which are chemically very stable. However, during the production process, a small amount of moisture may be present, requiring drying before use.

[0003] Chinese Patent CN212081840U discloses a distributed lithium battery drying device, including a dryer with fixed boxes fixedly connected to the left and right sides of the dryer's inner cavity. This invention utilizes a connecting column moving upwards in conjunction with a limiting groove, simultaneously pulling an arc-shaped ring to the left. The arc-shaped ring's leftward movement causes a sliding plate to move to the left. The sliding plate, in conjunction with a sliding groove, compresses a spring for shock absorption, releasing the locking teeth from the separator. The user can then adjust the height of the separator to increase the space for more lithium batteries to dry. Finally, the rotating rod is rotated in the opposite direction, causing the bushing and connecting column to move downwards. This downward movement of the connecting column causes the arc-shaped ring and sliding plate to move to the right. Finally, the sliding plate, in conjunction with the locking teeth, locks the separator in place. This design solves the problem of existing lithium battery drying devices lacking adjustable space, increases user processing efficiency, reduces user working time, and improves the practicality of the drying device.

[0004] However, the above technical solution has the following drawbacks: In the above distributed lithium battery drying device, multiple batteries are stacked on the separator, and there is obstruction between multiple battery cells, which makes the drying time of the battery in the middle longer.
