Training: generally refers to the implementation of a series of process measures for the first charge of the battery to stabilize its performance, including low current charging and discharging, maintaining, temperature constant below 60°C, etc. It also specifically refers to the first charge to make the battery stable. Complete the electrode activation charge and discharge process.
Capacity classification: A simple understanding is capacity sorting and performance monitoring and ranking.
The details of lithium battery manufacturing process are as follows:
1. Cell assembly: mainly including winding or rolling and pre-cell. - Packaging, electrolyte injection and other processes have high requirements for precision, efficiency and consistency.
2. Activity detectionBattery core formation: including detection of capacity division, battery core formation, etc.
3. Pole piece production: including mixing, coating, rolling, slitting, compressing, molding and other processes. It is the basis of lithium-ion battery manufacturing and plays an important role in accuracy, performance and performance. performance of pole piece manufacturing equipment. There are high demands on the level of automation, stability and production efficiency.
4. Battery packaging: including classification, testing, series and parallel combination of the single cells that make up the battery, and performance and reliability testing of the assembled battery.
Lithium battery equipment generally refers to various manufacturing equipment used in the production process of lithium batterieslithium-ion batteries. Lithium-ion battery equipment affects the performance and cost of lithium-ion batteries. The production process for lithium-ion batteries is long. There are more than 50 processes in the production process, which requires more than 50 types of equipment to complete the manufacturing of each process. The links between the processes determine the strong specificity of lithium-ion batteries. equipment.
Lithium battery equipment is used in various lithium battery production processes. Lithium battery materials are mainly composed of positive and negative electrode materials, electrolytes and separators, as well as packaging and other parts. Lithium batteries are essential basic equipment for the lithium battery manufacturing industry.
The production and manufacturing of lithium-ion batteries is a process closely related to variousstages of the process. Overall, lithium battery production includes the pole piece manufacturing process, the battery assembly process, and the final processes of liquid injection, precharging, forming, and aging. In these three stages of the process, each process can be divided into several key processes, and each stage will have a great impact on the final performance of the battery.
With the continuous progress of science and technology, lithium batteries have very broad development prospects in the new energy sector. Nowadays, it is widely used in life. For example, lithium batteries are used in mobile phones, computers, watches, electric vehicles, household appliances and other common equipment. In addition, lithium batteries are also widely used in energy storage systemssuch as power, wind, hydroelectric and solar power plants.
