Construction of Lithium - iron - phosphate Battery Clean Workshop
2024.11.06
In the current era of rapid technological development, lithium - iron - phosphate batteries, as a key force in the new energy field, have unprecedentedly high requirements for the production environment. Guangzhou Kunling Purification Equipment Co., Ltd. has rich experience and professional technology in the construction of lithium - iron - phosphate battery clean workshops. Today, let's take an in - depth look at this crucial construction field.
I. Requirements of Lithium - iron - phosphate Battery Production for Clean Workshops
The performance and quality of lithium - iron - phosphate batteries are closely related to the production environment. During the battery manufacturing process, even tiny dust particles can cause a short circuit in the battery and reduce its charge - discharge performance, thereby affecting the overall service life and safety of the battery. In addition, impurities such as moisture and microorganisms in the air can also have an adverse impact on battery materials and production processes. For example, excessive moisture may react chemically with battery materials and damage the chemical structure of the battery. Therefore, in order to ensure the high - quality production of lithium - iron - phosphate batteries, a clean workshop with strict control of temperature, humidity, and air cleanliness is essential.
II. Planning and Design before Construction
(I) Process Layout Planning
Before the construction of the lithium - iron - phosphate battery clean workshop, we first conduct detailed process layout planning. According to the production process of lithium - iron - phosphate batteries, from the storage and pretreatment of raw materials, electrode manufacturing, battery assembly to the final inspection process, each step requires specific space and environmental conditions. Our engineers will deeply understand the production process and reasonably divide different functional areas to ensure that the flow paths of materials and personnel are the shortest and do not interfere with each other. For example, the electrode coating area is set in a relatively independent area with more precise temperature and humidity control because the electrode coating has extremely high requirements for the environment, and such a layout can reduce the impact of external factors on the coating quality.
(II) Determination of Cleanliness Level
According to the production standards of lithium - iron - phosphate batteries, we determine the appropriate cleanliness level. Generally speaking, for the core production processes of lithium - iron - phosphate batteries, such as cell assembly and liquid injection processes, a cleanliness level of 10,000 grade or even higher is required. During the design stage, we will accurately calculate parameters such as the number of air changes and the grade of air filters required in different areas based on international standards and actual production requirements to ensure that the air in the workshop is always kept within the specified cleanliness range.
III. Key Links during the Construction Process
(I) Installation of Enclosure Structure
The enclosure structure is the key to ensuring the airtightness and stability of the clean workshop. We use high - quality color steel plates as the wall and ceiling materials of the workshop. These color steel plates not only have good flatness but also have a specially treated surface that is not easy to accumulate dust and is easy to clean. During the installation process, our construction team will strictly control the splicing gaps between the plates and use professional sealant for sealing to ensure the airtightness of the entire enclosure structure. At the same time, for the floor of the workshop, we will choose anti - static, wear - resistant, and seamless epoxy floor materials to prevent dust generation from the floor and static electricity from causing harm to battery production.
(II) Ventilation and Air Purification System
The ventilation and air purification system is the core of the lithium - iron - phosphate battery clean workshop. We install high - efficiency particulate air (HEPA) filters and ultra - low penetration air (ULPA) filters to filter the incoming air layer by layer to remove impurities such as dust particles and microorganisms. The air - conditioning system is responsible for accurately controlling the temperature and humidity in the workshop. According to the requirements of different production areas, the temperature is controlled between 20 - 25 °C, and the relative humidity is controlled between 40% - 60%. We adopt advanced variable - frequency technology so that the air - conditioning system can automatically adjust the operating power according to the actual temperature and humidity conditions in the workshop, ensuring the stability of the environment and achieving energy saving and consumption reduction.
(III) Electrical and Lighting System
In terms of the electrical system, we must ensure stable and reliable power supply in the workshop. Considering the high - power requirements of lithium - iron - phosphate battery production equipment, we will design a reasonable power wiring, use high - quality wires and cables, and be equipped with an uninterruptible power supply (UPS) system to prevent losses caused by sudden power outages during production. The lighting system selects clean - room - specific luminaires without flicker and with uniform brightness, and reasonably adjusts the lighting intensity according to different production operation areas to avoid the impact of overly strong or weak light on the vision of operators and production processes.
IV. Construction Quality Control and Testing
(I) Quality Control System
During the entire construction process of the lithium - iron - phosphate battery clean workshop, we have established a complete quality control system. From the incoming inspection of raw materials, each process during the construction process to the final overall acceptance, there are strict quality standards and inspection processes. Our quality management personnel will regularly conduct inspections on the construction site and issue rectification notices in a timely manner for links that do not meet the quality requirements to ensure that every construction detail complies with the design requirements and relevant standards.
(II) Testing Methods and Acceptance Standards
After the construction is completed, we will use multiple testing methods to conduct a comprehensive test on the clean workshop. For example, a dust particle counter is used to detect the concentration of dust particles in the air, a temperature and humidity sensor is used to verify the accuracy of the temperature and humidity control system, and an air volume hood is used to detect the air volume of the ventilation system. Only when all the test indicators meet the designed cleanliness level, temperature and humidity range, and other relevant standards can the clean workshop be officially delivered for use, providing a reliable environmental guarantee for the high - quality production of lithium - iron - phosphate batteries.
Guangzhou Kunling Purification Equipment Co., Ltd. always adheres to quality as the core and technology as the driving force in the construction of lithium - iron - phosphate battery clean workshops, contributing to the development of the new energy industry and creating a high - standard clean production space.
