Technical parameters：

Application case

Experiment preparation

Material preparation: Prepare an appropriate amount of assembled soft-pack lithium battery semi-finished products, including the batteries that have completed the assembly of positive and negative electrode sheets, electrolyte injection, and initial packaging.

Tools: In addition to the two-top-side-sealing integrated machine, prepare auxiliary tools such as gloves, scissors, and rulers.

Environment preparation: Ensure that the operation area is clean and dust-free, and that the temperature and humidity meet the technical requirements to avoid the impact of static electricity and dust. The operating area should be equipped with an inert gas (such as argon) protection system to prevent the battery from reacting with air contact.

Experimental procedure

Battery pretreatment:

Place the assembled soft-pack lithium battery semi-finished product on the operating table to check whether there is leakage or other defects.

Confirm the initial packaging effect of the battery, ensure that the aluminum plastic film and the battery body fit well, no bubbles and leakage sealing phenomenon. 

Parameter setting:

According to the battery specifications and packaging requirements, set the sealing parameters of the dual top side sealing machine, including sealing temperature, sealing time, and sealing pressure.

It can be tested in small batches first and adjusted to the best state before being formally put into production.

Battery loading:

Place the battery on the workbench of the dual top side sealing machine to ensure the correct and stable position of the battery.

Adjust the fixture to keep the battery in place and avoid moving during the sealing process.

Top seal:

Start the top sealing procedure, and the sealing device will automatically seal the top of the battery.

Ensure that the sealing line is continuous, smooth and free of bubbles. When the sealing is complete, the sealing device automatically returns.

Side seal:

Move the top sealed battery to the side sealing station to ensure that the side sealing position is correct.

Start the side sealing procedure, and the sealing device will automatically seal the side of the battery.

Ensure that the sealing line is continuous, smooth and free of bubbles. When the sealing is complete, the sealing device automatically returns.

Quality inspection:

Carefully check each piece of packaged soft pack lithium battery to ensure that the top and side sealing lines have no leakage sealing, no bubbles, no burning and other undesirable phenomena.

Use tools such as microscopes and thickness gauges for detailed inspection and record relevant data.

Performance test:

Some samples were randomly selected for charge-discharge cycle test to evaluate the key indicators such as capacity retention rate and internal resistance.

Record test results and analyze the impact of packaging on battery performance.

Result analysis

Through the use of dual top-side sealing all-in-one machines, the company achieved the following results in the packaging process of soft-pack lithium batteries:

Improve the packaging quality: The high-precision sealing system ensures the continuity and flatness of the top and side sealing lines, reduces the phenomenon of leakage sealing and bubbles, and improves the sealing and consistency of the battery.

Enhanced safety: The high quality package reduces the safety risks of the battery during the charge and discharge process and improves the safety of the battery.

Improved production efficiency: The automated all-in-one design significantly reduces packaging time, improves production efficiency, and reduces labor costs.

Reduce the rate of defective products: standardized operation process and high-precision equipment reduce the error caused by human operation and reduce the rate of defective products.
