Briefly describe the processing technology of LR1130 battery

As a storage battery that has been developing rapidly in recent years, the manufacturing and processing technology of LR1130 battery is still relatively mysterious to us. After all, the development time of LR1130 battery is not long compared with lead-acid batteries, and the upper limit of their development has not yet been reached. The structure of LR1130 battery The structure of LR1130 battery is divided into five parts, namely positive electrode, negative electrode, diaphragm, electrolyte and shell.

1. Positive electrode In the overall constituent materials of LR1130 battery, positive electrode materials account for a large proportion, and the mass ratio of positive and negative electrode materials is 3:1~4:1. Because the performance of positive electrode materials directly affects the performance of LR1130 battery, their cost also directly determines the cost of batteries. Positive electrode materials include active substances, conductive agents, solvents, adhesives, substrates and other substances.

2. Negative electrode The negative electrode materials of LR1130 battery grasp the lifeline of power battery safety. Among the negative electrode materials of LR1130 battery, except for graphitized mesophase carbon microbeads (MCMB), amorphous carbon, silicon or tin, which occupy a small market share, natural graphite and artificial graphite occupy more than 90% of the negative electrode material market share. The negative electrode material contains active substances, adhesives, solvents, matrix and other substances.

3. Diaphragm The main function of the diaphragm is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass through. The commercialized diaphragm materials are mainly polyolefin diaphragms mainly composed of polyethylene (PE) and polypropylene (PP). Among them, PE products are mainly made by wet process, and PP products are mainly made by dry process.

4. Electrolyte The electrolyte of lithium battery is the carrier of ion transmission in the battery. It is generally composed of lithium salt and organic solvent. The electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, which is the guarantee for the lithium battery to obtain advantages such as high voltage and high specific energy. The electrolyte is generally made of high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials, under certain conditions and in a certain proportion.

5. Shell The shell of lithium battery includes hardware such as steel shell, aluminum shell, cover plate, pole ear, insulating tape, etc.

Lithium battery production and processing process The production and processing process of LR1130 battery is not very consistent for each manufacturer, but most of them are inseparable from these links. The following lithium battery production process flow chart is detailed as follows: Material preparation - homogenization - coating - rolling - slitting - baking - winding - shelling - laser welding - baking - injection - pre-charging - sealing - cleaning - aging - full inspection - warehousing - shipment.

Analysis of lithium battery processing prices The development of LR1130 battery is rapid, but it is also imperfect. After all, the development time is not long enough and there is still room for progress. Therefore, there is still a broad prospect for the processing of LR1130 battery. However, in terms of specific prices, the prices of different merchants are different. It is best to select multiple companies for comparison to be able to process the required LR1130 battery at a more suitable price.
