Electronic enthusiasts provide you with the top ten production processes of automotive power batteries. This article first introduces the concept and structure of power batteries, then introduces the seven characteristics of power batteries, and finally introduces the top ten production processes of automotive power batteries and the characteristics of power batteries. application. Power battery overview
Power batteries are the power sources that provide power for tools, mostly referring to batteries that provide power for electric cars, electric trains, electric bicycles, and golf carts. It is mainly different from the starting battery used to start the car engine. Valve sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries are mostly used.
Power battery structure
1.Battery cover
2. Positive electrode--the active material is lithium cobalt oxide
3. Diaphragm - a special composite membrane
4. Negative electrode——active material is carbon
5. Organic electrolyte
6. Battery case
Seven characteristics of power batteries
1. Super long life. The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times. The lithium iron phosphate power battery produced by Shandong Haiba Energy Group Co., Ltd. has a cycle life of more than 2,000 times. Standard charging (5 hours rate) use, can reach 2000 times. Lead-acid batteries of the same quality last "half a year for new ones, half a year for old ones, and another half year for maintenance", which is 1 to 1.5 years at most, while lithium iron phosphate batteries will last 7 to 8 years when used under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries.
2. It is safe to use. Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganate will explode under strong collision and pose a threat to the life safety of consumers. Iron phosphate Lithium has undergone rigorous safety testing and will not explode even in the worst traffic accidents.
3. It can be charged and discharged quickly with a large current of 2C. Under a special charger, the battery can be fully charged within 40 minutes at 1.5C, and the starting current can reach 2C. However, lead-acid batteries currently do not have this performance.
4. High temperature resistance. The electric heating peak of lithium iron phosphate can reach 350℃~500℃, while the peak value of lithium manganate and lithium cobalt oxide is only around 200℃.
5. Large capacity.
6. No memory effect.
7. Small size and light weight.
The first step in the top ten production processes of automobile power batteries: positive and negative electrode homogenization workshop
The function of this workshop is to fully mix the materials used for the positive and negative electrodes with strictly calculated proportions in the homogenization tank. During this process, dust needs to be strictly controlled to prevent dust from affecting the consistency of the battery. Its dust control level Equivalent to medical grade.
The second process: coating workshop
In the coating workshop, the stirred slurry will be evenly attached to the aluminum foil, and then suspended and dried in an oven heated by special oil. The purpose is to avoid the flow of the slurry and ensure uniform adhesion. This is also an important step in ensuring the performance consistency of finished battery products.
The third process: rolling workshop
In the rolling workshop, the aluminum foil with the positive and negative electrode materials attached is rolled by a roller with a pressure of about 50 tons. On the one hand, the coated material is made more compact, the energy density is increased, and the thickness is ensured. On the other hand, Dust and humidity will also be further controlled. Unfortunately, there is still a certain gap between domestic materials and foreign materials in terms of thermal stability. In order to ensure safety and achieve better performance, BAK currently uses imported raw materials.
The fourth process: cutting the positive and negative electrodes
The rolled aluminum foil is cut according to the size required to produce the battery, and the generation of burrs (visible under a microscope) is fully controlled. The purpose of this is to prevent the burrs from piercing the separator and causing serious safety hazards. The current slitting speed in the slitting workshop is 60 meters per minute.
