Apply the coating.
This method reveals LiFePo4 Battery in a large aluminum (silver) and copper (yellow) foils. NCM’s ternary materials are coated in aluminum foil, while graphite is a negative active material, and copper foil is used to cover it. “White serves as a boundary.
126mm is the width of a whole roll of positive and negative electrode material. After that, I’ll cut it into seven 18mm-wide rolls. Each roll will be cut into several equal portions and then distributed evenly. – The components depict single cells in each segment of the diagram. That’s how many batteries you’ll get from the current price per tone of the material, which is currently priced at $20,000 per ton. High-intensity, high-temperature-resistant Mylar will be applied to each piece by an automated process. Weighted, A1, A2, A3, and lighter are the next five levels to be weighed. CPU wafers are the same here. They will produce multiple physical types in the same batch due to the cutting method. According to a person’s physical attributes, one’s carrying capacity will be divided.
Assembly
As a result of the electrodes’ distinct positive and negative divisions, automatic operation is ensured in this scenario. It is referred to as a divider because of the color of the cloth. The battery cell is still a bad one. The positive and negative electrodes need an electrolyte to start a chemical reaction. A lithium battery with charged ion output energy can be charged and discharged because lithium ions can flow between the positive and negative electrodes. Automatic roll-packing is carried out on the production line before the steel shell.
The steel shell is a single stamping mold piece with a thickness of less than a millimeter. Thus, steel must meet exacting standards for both strength and quality.
At this point, the negative electrode tab is attached to the steel shell using a spot weld. Our laser spot welding machine from Miyachi ensured pinpoint accuracy and high-quality results. Welding the bottom of the steel shell was a no-go for the spot welder. A copper nail was in his hand. He plugged it into the spot welder through the mysterious hole on the bottom. Now the negative electrode is attached to the steel case using a strip of nickel tape.
Argon is pumped into the glove box before the electrolyte is injected. The oxygen concentration in the sealed box gloves must be less than 10 parts per million (ppm) (precisely equal to an oxygen-free vacuum environment) to avoid electrode oxidation. The circulating purifying system delivers the electrolyte argon gas to the sealed box. and can clean the catalyst of hydrogen and oxygen via the hydrogen and oxygen reaction. The gadget’s desiccant collects moisture and dries the air within the box simultaneously.
Examine and Charge.
Injection of electrolyte into electrolyte removes all electrical charge. Until the positive and negative electrode states are stable enough to be used regularly, they must be charged through the first charge.
A “chemical reaction” is used to describe the initial charge. A second charge is needed after the initial charge to safeguard the electrode surface. The minimal self-discharge of LiFePo4 Battery can be attributed to this protective layer. The layer’s qualities also influence the battery’s performance and lifespan. As a result, the process of forming a company is critical. A volumetric cabinet can transform chemicals.
Batteries include chemicals. For the safety and longevity of the batteries, they must be packaged in boxes before shipping. The standard for each box is 200 pieces. They will maintain all of these parameters at a constant value. Otherwise, they will be labeled as “B” or “C” batteries.
