Nichwell Organic Solvent Purification System

Nichwell offers customers a fast, safe and easy-to-operate organic solvent purification system. This product provides laboratories with a system that meets the highest levels of security and can be customized as required.

Nichwell Organic Solvent PurificationSystem uses the working gas to pressurize the liquid level of the storage tank for solvent tank filling (99.99% nitrogen or higher purity gas is recommended). The solvent will enter the dual-column purification column that can remove water and oxygen through the pipeline system. The ultrapure solvent will flow into the solvent receiving bottle or reactor or glove box after the vacuum treatment.

Nichwell Contact Baking Automation Production Line

Process flow:

1. The "feeding conveyor" will stop when the three-cell battery pack (hereinafter referred to as the "battery pack") is moved to the designated position in front of the vacuum oven, and the battery pack will be sequentially moved to the vacuum oven by the "unloading robot 1". Inside (the oven has 30 layers, 6 per layer, and a total of 180 batteries can be placed);

2. Each vacuum baking system has 12 vacuum ovens and 2 cooling boxes. "Unloading robot 1" feeds the oven from right to left in about 15 minutes. After the robot finishes loading the first oven, it loads the second oven, and so on, between each oven. 15 minutes interval; set heating time (6 hours), baking temperature is 85 ° C;

3. After the baking is completed, the "Unloading Robot 1" puts the battery pack on the "Transition Conveyor Belt", the "Transition Conveyor Belt" stops the battery after it is transferred to the cooling box, and the "Unloading Robot 2" will "Transition The batteries on the "conveyor belt" are placed into the cooling box in turn. After the completion, the door is closed and cooled for five minutes. The battery is cooled to 45 ° C;

4. After the cooling is completed, the door of the cooling box is opened, and the "unloading robot 2" takes out the battery packs in turn, places them on the "unloading conveyor", and transfers them to the sorting process.

Features of Nichwell Vacuum Oven

1. Baking mode: The battery is directly placed on the heating plate, and the vacuum is used to dry quickly;

2. The sealing material on the automatic door is made of fluorine rubber, and the sealing surface on the oven is water-cooled;

Method for Drying Lithium Ion Battery Cells

In the production process of lithium-ion batteries, it is necessary to dry the battery cells after they are put into the shell or before they are put into the shell to ensure that the moisture content of the batteries is controlled within a certain range before the next liquid injection process can be performed. The high moisture content of lithium-ion battery cells will cause the moisture in the lithium battery to react with the electrolyte during the charge and discharge process, which will affect the life and performance of the lithium-ion battery. How to effectively reduce the moisture content of battery cells, improve production efficiency, and save costs is an important process issue in the industrialized production process of modern lithium-ion batteries.

An automated production line for lithium-ion batteries is provided. The integrated production line consists of an oven, a cooling glove box, a liquid injection glove box, a buffer glove box, a squeeze (static) vacuum box, a sealed glove box, and a discharge vacuum box. The oven and glove box are seamlessly connected to achieve continuous production. The oven and the glove box are seamlessly connected. After baking, the battery core is always kept in a water-free and oxygen-free glove box environment. The entire production line includes a cooling glove box, which has a fast cooling speed and a low cost operating environment without water and oxygen. It guarantees that the battery cell is from baking to filling, and the sealing process is operated in a controlled anhydrous and oxygen-free environment, which provides the most solid protection for the quality of the battery. Functions such as automatic transmission can realize the automatic production of batteries, greatly improve production efficiency, and save human capital. The configuration of the MES manufacturing execution system and the configuration of the MES manufacturing execution system have achieved low information production costs, and customers do not need to build a drying room and purchase a rotary dehumidification system, Saving investment costs and operating costs.
