In the manufacturing process of lithium batteries or battery packs, over 20 steps involve welding to achieve conductive connections or seals.

In a significant development for the battery industry, a technologically advanced coin cell crimper machine has been introduced, promising to streamline and enhance the manufacturing process of coin cell batteries. This cutting-edge device marks a leap forward in the field of battery assembly, offering increased efficiency, precision, and reliability. With its state-of-the-art features and robust capabilities, the coin cell crimper machine is set to revolutionize battery production worldwide.

On January 10, BMW Group officially announced that it will invest 650 million euros to renovate the Munich plant in Germany, including four buildings, a new car assembly line with logistics area and new body shop, and will produce pure electric models as early as the end of 2027. The BMW Group said that the Neue Klasse pure electric model will be officially put into production from 2026, and the 75-year era of internal combustion engine vehicles at the Munich plant will end by the end of 2027, making the plant the first in the BMW Group's global production network to successfully complete the electric transformation from the end of 2027.

The preparation of electrode is the most critical part in the whole process, and the quality of electrode directly affects whether the next step can be carried out. Slurry preparation is a non-Newtonian high-viscosity fluid formed by mixing living matter, adhesive, solvent, thickener and other powders evenly. The fluid needs to have a certain viscosity, good fluidity and a small enough particle size. What kind of equipment is needed for the preparation of electrode to meet the requirements?

The process mainly includes the following steps: 1. Preparatory work 2. Size mixing 3. Prepare the electrode sheet 4. Dry 5. Equipped with button battery

In the manufacturing process of lithium-ion batteries, there are three very key items that must be strictly controlled: first, dust; Second, metal particles; The third is water. Dust and metal particles are not well controlled, which will directly lead to internal short circuit of the battery, fire and burning safety accidents; If the moisture is not effectively controlled, it will also cause greater harm to the battery performance and lead to serious quality accidents! Therefore, for the control of the water content of the main materials such as electrode sheets, separators, and electrolytes in the process, it is very critical, and there can be no relaxation. The following is detailed from three aspects: the harm of water to lithium batteries, the source of water in the process, and the control of water in the process.
