Key Points for Planning and Implementation of Lithium ion Power Battery Production Line

1. Scientific assessment of geographical location

Prioritize building factories in areas close to the vehicle manufacturing base to reduce logistics costs and improve supply chain response speed. At the same time, it is necessary to evaluate the stability of power supply, the completeness of infrastructure support, and policy support to ensure that the site selection meets long-term operational needs.

2. Technical and Economic Analysis of Equipment Procurement

Match specialized equipment for electrode preparation, module assembly, testing and packaging based on battery models (such as square/cylindrical/soft pack) and target production capacity. Focus on examining the technical qualifications, equipment automation level, and after-sales maintenance response capabilities of suppliers to avoid production line bottlenecks.

3. Standardized design of production process

Develop a complete SOP process based on battery type, from electrode material mixing, coating and drying to finished product packaging. By introducing MES system to monitor the efficiency of process connection in real time, continuously optimize process parameters (such as temperature/pressure control) to improve the yield rate.

4. Full chain quality control system

Establish a three-level quality control system from raw material incoming inspection (such as lithium salt purity testing), process inspection (electrode thickness sampling) to finished product performance testing (charge discharge cycle testing). Implement ISO9001 certification and regularly calibrate testing equipment to ensure data traceability.

5. Safety production and environmental compliance
Select explosion-proof electrical equipment that meets CE certification, equipped with exhaust gas treatment systems (such as SCR catalytic devices) and wastewater recovery facilities. Regularly conduct EHS audits and implement graded control measures for key points such as chemical solvent storage and dust explosion risks.

6. The hierarchical allocation of human resources

According to the degree of automation, allocate positions for process engineers, equipment maintenance specialists, and quality inspection technicians, and establish a skill matrix training system. Retain core technical personnel through a performance-based compensation structure to ensure the continuous improvement capability of the production line.

Taking into account the above factors, the construction of lithium battery production lines requires cross departmental collaboration to achieve a dynamic balance of technology, cost, and safety indicators, ultimately forming a production system with market competitiveness.
