The prismatic lithium battery pack assembly line represents an essential element in the production of lithium-ion batteries, specifically those utilized in electric vehicles (EVs) and energy storage solutions. Gaining insight into the workflow and technologies that constitute these assembly lines can provide valuable knowledge regarding the efficiency and scalability of battery manufacturing.
The first step encompasses the selection and preparation of materials, alongside the creation of electrodes. This phase entails mixing active components, applying coatings onto current collectors, and subsequently drying and compressing these electrodes. Precision during this stage is vital for ensuring the batteries' quality and performance.
In the cell assembly stage, the electrodes are precisely cut and organized into cells. Regarding prismatic cells, this entails the meticulous stacking of electrodes with separators. Advanced automation technologies are frequently employed to sustain high levels of accuracy and efficiency during this operation.
Laser welding is the preferred technique for sealing the cells, particularly the upper covers of prismatic lithium batteries. This approach guarantees precise and robust seals, which are crucial for maintaining the safety and longevity of the batteries. After this, the cells are filled with electrolyte and thoroughly sealed.
Following the sealing process, the newly sealed cells undergo a formation process, whereby they are charged and discharged multiple times to create the solid electrolyte interphase (SEI) layer. This is then succeeded by an aging phase in which performance and stability are assessed. This step is critical for confirming the reliability of the batteries prior to their integration into packs.
The concluding stage involves the integration of the cells into modules and packs. This process includes the installation of battery management systems (BMS) and other electronic components essential for monitoring and regulating battery performance. Subsequently, these modules undergo rigorous testing for quality and performance before being packaged for distribution.
