Lithium-ion Pouch Cell Production Line Building Project in Europe

Jun 28,2019

Project Name: Lithium-ion Pouch Cell Production Line Building Project in Europe


Description: Xiamen TOB New Energy Technology Co., Ltd. designs and builds a lithium-ion pouch cell production line for the customer's battery factory. We provide a full set of battery technology, production line equipment and some consumables. After the delivery of the project, TOB New Energy will send engineers to the factory to complete the commissioning of the equipment.


Date: 2019


Location: Europe



After fully verifying its material system and production process, the customer decided to build a lithium-ion pouch battery production line for its own battery factory. The manufacturing process of the battery can be divided into three links in sequence: the front section, the middle section, and the back section. To put it simply, the first stage is the process of positive and negative electrode production. The middle section is the process of battery production, including five processes including punching, stacking/winding, welding, heat sealing, drying, and electrolyte filling. The core link is the stacking/winding process, which has the highest value in the entire middle process, accounting for about 70%. The latter part is the link of inspection and assembly. This time, the lithium-ion soft-pack battery production line built by Xiamen TOB New Energy Technology Co., Ltd. for customers uses the stacking process. The whole production line completely includes the slurry process, electrode making process, assembly process and chemical formation process of the battery, which can fully meet the daily production needs of customers.
