Tunnel type fully automatic vacuum drying system
Product Description 1. Overview:

Fully embody the design concept of Industry 4.0, combined with the specialized assembly line design concept, effectively provide comprehensive solutions for the drying process of the new energy lithium battery industry
Case
2、 The necessity of vacuum drying:

The impact of moisture on the performance of lithium batteries is multifaceted, including capacity, internal resistance, internal pressure, self discharge, power density, cycle life, charge discharge rate, safety, consistency, and other indicators. Excessive moisture can lead to performance degradation, expansion, self ignition, and even explosion. Especially for power batteries with higher requirements for consistency and safety of the entire battery pack, excessive moisture is unacceptable
Vacuum drying is an important barrier to improve battery performance and ensure battery safety. Therefore, lithium battery manufacturers will adopt vacuum drying technology at multiple water control points on the production line to minimize the moisture content in the batteries as much as possible
3、 Limitations of traditional vacuum drying methods:

1. Excessive drying time has become a bottleneck in production

2. The vacuum degree is low and cannot effectively remove water, oxygen, and impurities from the battery
3. Poor temperature uniformity affects the consistency of the battery
4. Due to multiple manual operations, the product is exposed to the atmospheric environment multiple times during the transfer process, making it susceptible to secondary pollution and resulting in poor consistency among multiple batches of the product
5. Need a drying room, high operating costs
4、 New vacuum drying solution features:

1. Following the concept of Industry 4.0, fully automated operation, and intelligent control
2. The production efficiency is several times higher than traditional methods
3. It is a multi process continuous automation system, where each process chamber is seamlessly connected, completely isolated from the atmosphere during the transfer process, with high efficiency and low energy consumption
4. Each process specialty completes a single function, achieving a constant high vacuum, low dew point, and high temperature uniformity drying environment, greatly improving the performance parameters of the product, while ensuring consistency between single and multiple batches of products
5. No need for a drying room, significantly reducing operating costs
