Case: Energy Storage Battery Production Line

Background and Requirements:

A battery manufacturing company focusing on energy storage systems plans to produce lithium iron phosphate batteries (LiFePO4) for home energy storage systems. With the rapid development of the energy storage industry, customer demand for batteries has increased significantly, especially for higher energy density, long life cycle and safety. In order to improve production efficiency and product quality, the company decided to introduce a semi-automatic stacking machine into the production line to meet the growing market demand.

Equipment Selection:

The company selected a semi-automatic stacking machine suitable for energy storage battery production with the following features:

Adaptability: Suitable for different types of positive, negative and diaphragm materials, able to cope with the specific needs of lithium iron phosphate batteries.

High-precision stacking system: With a precise alignment system to ensure alignment between electrodes and diaphragms, reducing material waste.

Efficient production capacity: With a high level of automation, reducing manual intervention, and improving production speed and consistency.

Compact design: Small footprint, suitable for limited production space in the factory.

Process flow

1. Preparation stage:

Material preparation: The production of energy storage batteries requires lithium iron phosphate (LiFePO4) as the positive electrode material, graphite as the negative electrode material, and polyethylene (PE) diaphragm sheets. After cutting, coating and pretreatment, the materials are ready for lamination.

Electrode sheet and diaphragm sheet inspection: Before production, all electrode sheets and diaphragm sheets need to be quality checked to ensure that they are defect-free, surface clean, and meet battery design requirements.

2. Semi-automatic lamination process:

Automatic feeding: After the operator puts the material into the feed trough, the equipment automatically feeds the positive electrode sheet, negative electrode sheet and diaphragm sheet into the lamination machine. The automatic feeding system ensures that each layer of material can be accurately fed in.

Automatic alignment: During the lamination process, the semi-automatic lamination machine uses an advanced alignment system to ensure that each layer of electrode sheet and diaphragm sheet is aligned, reducing deviations and ensuring battery consistency.

Lamination and pressing: After each layer of positive electrode, negative electrode and diaphragm is stacked, the equipment will perform a certain pressure pressing to ensure that each layer of electrode and diaphragm is tightly combined to avoid interlayer detachment.

Automatic compensation: The equipment has an automatic pressure compensation function, which can detect the pressure changes during the lamination process in real time to ensure that the lamination force of each layer of electrode sheets is uniform and consistent.

Manual monitoring: Although it is a semi-automatic equipment, the operator needs to monitor the lamination process to ensure that the equipment runs smoothly and to discover and solve potential problems in time.

3. Quality control:

Accuracy detection: After each round of lamination is completed, the equipment will perform an alignment accuracy test on the electrode sheet to ensure the consistency of the battery cell. Any error will trigger an alarm to remind the operator to make adjustments.

Size detection: After lamination is completed, the size of the battery cell will be automatically detected to ensure that the product meets the specification requirements. Any deviation will cause the equipment to automatically shut down to prevent unqualified products from flowing into subsequent processes.

Compactness inspection of the battery cell: The lamination strength of the battery cell is checked through the pressure monitoring system to ensure the density and stability of each battery cell.

4. Post-stacking processing:

The battery cells that have completed the stacking will be sent to the next process - packaging, injection and activation. The high-precision work of the semi-automatic stacking machine makes the subsequent packaging and injection smoother, avoiding packaging difficulties caused by deformation or unevenness of the battery cells.

Challenges and solutions:

Differences in material adaptability: There are many types of electrode and diaphragm materials in the production of energy storage batteries, which may affect the stacking accuracy. To solve this problem, the manufacturer provides a variety of adjustment options for the characteristics of different materials, allowing operators to adjust parameters such as pressure, alignment accuracy and stacking speed according to the specific material type.

Stacking layer requirements: Energy storage batteries usually require more stacking layers, which increases the complexity of stacking. The pressure regulation and automatic control of the equipment solves the problem of uneven pressure in the multi-layer stacking process, thereby ensuring the consistency of the battery.

Manual monitoring and operator training: Since the semi-automatic stacking machine still requires manual intervention, the operator needs to receive comprehensive training to ensure that any problems in production can be discovered and handled in a timely manner. The factory regularly organizes technical training to improve the skill level of operators.

Experimental results and achievements:

Improved production efficiency: Compared with the traditional manual lamination method, the semi-automatic lamination machine has increased production efficiency by about 40%. The lamination process is more efficient and reduces the intensity of manual labor.

Consistency and quality control: Through the precise alignment system and pressure control system, the lamination quality of the battery core has been significantly improved, and the internal resistance and capacity distribution of the battery are more uniform.

Enhanced flexibility and adaptability: The semi-automatic lamination machine can be quickly adjusted to meet the production needs of energy storage batteries of different models and specifications. It is highly flexible and can cope with a variety of production situations.

Summary:

By introducing the semi-automatic lamination machine, the company has successfully improved the efficiency and product quality of the energy storage battery production line. The high precision and automated operation of the equipment reduce manual intervention and ensure the consistency and stability of the battery. At the same time, the participation of operators and technical training enable the production process to maintain a certain degree of flexibility and adapt to the changing needs of the market. In the future, the company plans to continue to improve the level of automation, further expand the production scale, and enhance the production capacity and market competitiveness of energy storage batteries.
