Technical parameters：

Application case：

Experiment preparation

Material preparation: Prepare an appropriate amount of lithium metal raw materials to ensure high purity and no impurities.

Tools: In addition to the lithium metal automatic production machine, you must prepare safety protective equipment, such as gloves, goggles, and ESD clothes.

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

Experimental procedure

Raw material preparation:

Put the lithium metal raw material into a special container to ensure that the surface of the raw material is clean and no oxidation.

Seal the container and pass an inert gas (such as argon) to remove the air in the container and prevent the oxidation of the lithium metal.

Raw material loading:

Connect the sealed container to the feed port of the lithium metal automatic producer.

Start the equipment and automatically transmit the lithium metal raw material to the production system.

Filmmaking parameter setting:

Set the parameters of the production system, including thickness, width, length, etc., according to the required lithium metal sheet specifications.

Adjust the temperature control device and set the appropriate temperature to ensure that unnecessary physical or chemical changes do not occur during the production of lithium metal.

Automatic production:

Start the lithium metal automatic production machine, and the equipment will automatically complete the rolling and cutting process of lithium metal.

The calender uniformly calends the lithium metal raw material to the desired thickness.

The cutting device cuts the rolled lithium metal sheet to the desired size and shape.

The prepared lithium metal sheet is automatically collected into the specified container.

Quality inspection:

Carefully check each prepared lithium metal sheet to ensure uniform thickness, smooth surface, no cracks and impurities.

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

Electrode assembly: 

The qualified lithium metal sheet is sent to the subsequent battery assembly line for assembly together with the positive electrode material, diaphragm and other components.

Ensure good contact between lithium metal sheet and other components to avoid short circuit and leakage. 

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 the test results and analyze the influence of lithium metal on the performance of the battery.

Result analysis

Through the use of lithium metal automatic production machines, the company achieved the following results in the preparation of high-performance soft-pack lithium batteries:

Improved production accuracy: The automated production system ensures that the thickness and size of the lithium metal sheet are highly consistent, improving the quality of the electrode material.

Improved safety: Inert gas protection system and strict safety protection measures effectively prevent dangerous reactions between lithium metal and air, ensuring the safety of operators.

Enhanced battery performance: high-quality lithium metal sheets significantly improve the energy density and charge and discharge efficiency of the battery, extending the cycle life of the battery.

Improve production efficiency: The automated production process reduces the manual operation time, improves production efficiency and reduces production costs.
