The LiFePo4 battery is revealed in huge aluminum (silver) and copper (yellow) foils using this LFP battery Manufacturers procedure. NCM's ternary materials are coated in aluminum foil, whereas graphite is a negative active substance that is covered in copper foil.
Automatic Operation
In this circumstance, automatic operation is ensured by the electrodes' unique positive and negative divisions. Because of the color of the cloth, it is referred to as a divider. The battery cell is still defective. To initiate a chemical reaction, the positive and negative electrodes require an electrolyte.
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 packaging is carried out on the production line in front of the steel casing.
Steel Shell Quality
The steel shell is a single stamping piece less than a millimeter thick. Thus, the steel must meet strict standards of strength and quality.
At this stage, the negative electrode tab is attached to the steel sheath using spot welding. Our laser spot welding machine from Miyachi delivers the highest precision and high-quality results. Welding of the base of the steel body failed spot welding. In his hand was a copper nail. He connected it to a spot welder through a mysterious hole in the bottom. The negative electrode is now attached to the steel case with a strip of nickel tape.
Reaction of Chemicals
Prior to electrolyte injection, argon is pumped into the glove box. The oxygen concentration in sealed gloves should be less than 10 ppm (parts per million) (exactly equal to an oxygen-free vacuum environment) to avoid oxidizing the electrode. The circulating cleaning system supplies gaseous argon electrolyte to a sealed box. and can purify the catalyst of hydrogen and oxygen through the reaction of hydrogen and oxygen. The gadget's desiccant collects vapors and dries the air inside the box.
Examine and Charge.
Injecting an electrolyte into an electrolyte removes all electrical charge. Until the states of the positive and negative electrodes become stable enough for regular use, they must be charged by means of the first charge.
"Chemical reaction" is used to specify the initial charge. A second charge is required after the initial charge to protect the electrode surface. The minimal self-discharge of a LiFePo4 battery can be explained by this protective layer. Layer quality also affects performance and battery life. As a result, the company formation process is critical. The bulk cabinet can convert chemicals.
Batteries contain chemicals. For the safety and durability of batteries, they must be packed in boxes before shipping. The standard for each box is 200 pieces. They will keep all these parameters at a constant level. Otherwise, they will be labeled as "B" or "C" batteries.
