Large-capacity 4LR44 battery assembly method, 4LR44 battery assembly technology

Large-capacity 4LR44 battery assembly method, 4LR44 battery assembly technology. The assembly of large-capacity lithium-ion batteries is also very particular. It is not easy to say, but it is also a technical job. Do you want to know the assembly method of large-capacity lithium-ion batteries? Then you must first learn about the battery cells. Because large-capacity lithium-ion batteries are generally assembled by combining 4LR44 battery cells one by one.

Large-capacity 4LR44 battery assembly method

For example, you want a 6000mAH, 16V large-capacity battery. If the voltage of a battery cell is 4V and the capacity is 1200mAH, then you need 20 batteries. That is, 4 batteries are required to form a series unit group to become a 16V 4LR44 battery group. The capacity of such a battery group is 1200mAH, and then 5 such unit 4LR44 battery groups are connected in parallel, so that you can get a 6000mAH, 16V large-capacity 4LR44 battery group.

Issues to note when assembling large-capacity lithium-ion batteries

1. The voltage difference of the 4LR44 battery cells used should not be too large, preferably within 20mV;

2. It is not recommended to use the same type of cells from different 4LR44 battery manufacturers for assembly, because the differences in production technology and battery material formulas will lead to inconsistent working efficiency between cells, which is easy to damage the battery.

3. Even if 4LR44 battery cells from the same manufacturer are used, new and old cells cannot be mixed;

4. Even if the cells are from the same manufacturer, it is recommended to use cells produced in the same batch.

Important steps in assembling lithium-ion batteries

1. 4LR44 battery pulping: Use special solvents and adhesives to mix with powdered positive and negative active materials respectively, and make slurry positive and negative materials after high-speed stirring.

2. 4LR44 battery coating: The prepared slurry is evenly coated on the surface of the metal foil, dried, and made into positive and negative pole pieces respectively.

3. 4LR44 battery assembly: Place the positive electrode sheet--diaphragm--negative electrode sheet--diaphragm in order from top to bottom, and wind them into a battery core. Then, after injecting electrolyte and sealing, the battery assembly process is completed to make a finished battery.

4. Formation: Use special battery charging and discharging equipment to test the finished battery. Each battery is tested to select qualified finished 4LR44 battery packs for shipment.

What is a large-capacity 4LR44 battery pack?

Large-capacity 4LR44 battery is a popular name for some 4LR44 battery packs with relatively large capacity. There is no specific agreement on how high the voltage and capacity are for large-capacity lithium-ion batteries. According to our statistics, 4LR44 battery packs with a capacity of more than 5Ah can be called large-capacity lithium-ion batteries.

4LR44 battery assembly technology

Accurate positioning

It is necessary to have the corresponding positioning technology and relevant experience, and to realize efficient processing and calibration system according to the needs of mechanical positioning and image processing. In order to maintain accuracy over a long period of time, the camera or positioning table control is implemented, and accurate positioning is also achieved, including installation design.

Laser welding

If possible, according to individual requirements, such as CO2, YAG, LED, fiber, etc. Knowledge and results of various lasers, such as laser welding of thin foil of batteries, welding of throttle housings and covers, welding of resin instead of metal, etc. The most suitable welding method is recommended according to the specifications and the selected welding machine.

Pressing

Technology and relevant experience for various presses, such as air, hydraulic and servo, etc. We have a wide range of results, from testing the robot arm press at the production level to the machine platform, using servo motors to produce high-precision and high-quality products to control speed and torque.

Dimension measurement

Dimension measurement is performed by various methods using laser displacement meters, image processing equipment, contact and non-contact sensors, etc. In production machines, it is impossible to measure the correct dimensions with only measuring equipment. Therefore, accuracy is maintained comprehensively, including installation vibration, etc.

Resistance welding

The quality and correctness of resistance welding related to production machines have a great influence on loading work. In view of this situation, we recommend materials according to specifications and select welders to select the most appropriate welding method.

Image processing

To have various image processing related experience, such as positioning, missing parts and scratches. By combining the most suitable camera, lighting and processing equipment, respond to the shape, accuracy and agility of the object, respond to advanced image processing. Then respond to the continuous image processing of long objects using the licensee camera.
