Interpretation of the production process and procedures of 4LR44 battery

Lithium-ion battery manufacturers interpret the production process and procedures of 4LR44 battery. Stirring, coating, winding, and testing are important production processes for 4LR44 battery. The process technology of 4LR44 battery is very strict and complex. The safety performance of lithium-ion battery products is directly related to the life and health of consumers. Naturally, lithium-ion battery production and manufacturing have high requirements for the performance, precision, stability and automation level of equipment.

Lithium-ion battery manufacturers interpret the production process and procedures of 4LR44 battery

Power lithium batteries and energy storage batteries have put forward higher technical requirements for battery consistency and quality control in lithium-ion battery production lines. Objectively, industrial robot technology must be introduced. However, most of the domestic robot system integration is concentrated in the automotive industry, machine tool loading and unloading and other large-scale contact manufacturing production lines. The important processes that 4LR44 battery have to go through during the production process are as follows:

Among the important processes in lithium-ion battery manufacturing, stacking, welding and cutting are three processes that are connected one after another, and they use automated or semi-automated special machines. Before the transformation, the connection and flow between the three processes required manual intervention, which could not achieve continuous production, had high labor intensity, and could not guarantee the consistency of battery products.

1. Stacking machine

It is important to use a diaphragm to separate the positive and negative electrode materials of 4LR44 battery to prevent the electrode from short-circuiting. The positive and negative electrodes are pre-loaded into the electrode magazine box, and the positive and negative electrodes are counted and stacked alternately by the manipulator. After the stacking is completed, the robot arm places the wire on the stacking table tooling, and the production line workers take it away for the next process.

2. Ultrasonic welding machine

The worker holds the battery after stacking and sends the tabs to the welding position. Through the high-frequency elastic vibration of the acoustic system, the positive and negative tabs of the stacked battery are welded under the clamping purpose of the static pressure between the workpieces. Under pressure, the metal surfaces are rubbed against each other to form a fusion between molecular layers. Its advantages are fast, energy-saving, high fusion strength, no sparks, and close to cold processing.

3. Cutting machine

The lithium-ion battery pole ear to be punched and cut is manually sent to the cutting machine blade. By controlling the movement of the cylinder, the cutting knife is driven to cut the protruding part of the pole ear. The cutting process must ensure the symmetry of the pole ears on both sides and the temperature of accuracy and quality.

Production process and links of 4LR44 battery

1. Slurry stirring is an important link in lithium-ion battery equipment. The positive electrode slurry of 4LR44 battery is composed of adhesives, conductive agents, positive electrode materials, etc., and the negative electrode slurry is composed of adhesives, graphite carbon powder, etc.; the preparation of positive and negative electrode slurries includes the mixing, dissolution, and dispersion of liquids and liquids, liquids and solid materials; the quality of slurry dispersion directly affects the quality and performance of 4LR44 battery.

2. Coating determines the consistency and superiority of the battery and occupies a technical position in battery manufacturing. Regardless of the type of battery produced (such as cylindrical or square), the coating machine used in manufacturing is the same; different types of batteries require different types of winding machines.

3. In addition to lithium-ion battery winding machines, there are also capacitor winding machines, textile winding machines, etc. According to the operation mode of the machine, it can be divided into manual winding machines, semi-automatic winding machines, and fully automatic winding machines.

4. The importance of testing items is becoming increasingly prominent. 4LR44 battery are prone to burn or explode due to short circuits, overcharging, etc., and will form finished batteries with protection boards in applications; in applications with higher energy density, 4LR44 battery need to be combined in series and parallel to form lithium-ion battery packs, which are managed by battery management systems (BMS).

It can be seen that the production process of 4LR44 battery is relatively long, including more than 50 processes, and more than 50 types of equipment are required accordingly. In recent years, lithium-ion battery production has developed towards integration, whole-line, and automation. Lithium-ion battery automation production lines supply standardized products to customers. Traditional development methods cannot cope with the rapidly changing needs of customers.

It can be seen that the production process and procedures of 4LR44 battery are closely related to product quality and safety. Every link in the production process of 4LR44 battery must be managed strictly and carefully to improve the safety performance of lithium-ion battery products.
