The establishment of internal control quality standards to meet the needs of customers, strict process management, and quality inspection, fully guarantee the excellent quality and more lasting endurance of our batteries.
18650 rechargeable battery is a common lithium battery model. The numbers 18650 represent the appearance size: 18 refers to the battery diameter of 18.0mm, and 650 refers to the battery height of 65.0mm.
The 18650 battery voltage is 3.7v, the common capacity is 1500mAh to 2600mAh, and the maximum can reach 3000mAh. In order to meet the needs of more equipment, the 18650 lithium battery pack came into being. It is assembled according to 18650 cells in series and parallel to achieve higher voltage and longer discharge time.
The above is the production process of 18650 lithium battery and the assembly method of lithium battery. The production process of 18650 lithium battery pack is quite complicated. After all, the safety performance of lithium ion battery products is directly related to the life and health of consumers. , precision, stability and automation level have higher requirements.
The main components of lithium-ion batteries include shell, electrolyte, anode material, cathode material, adhesive, copper foil and aluminum foil. Among them, the mass fractions of Co, Li, and Ni are 5%~15%, 2%~7%, 0.5%~2%, and metal elements such as Al, Cu, Fe, etc.; Materials and cathode materials account for about 33% and 10%, and electrolyte and separator account for about 12% and 30%, respectively. The main metals recovered in spent Li-ion batteries are Co and Li, mainly concentrated on the cobalt-lithium film on the anode material.
In particular, my country’s cobalt resources are relatively poor, and development and utilization are difficult, and the mass fraction of cobalt in lithium-ion batteries accounts for about 15%, which is about 850 times that of associated cobalt ore. At present, lithium-ion batteries with LiCoO2 as the positive electrode material are widely used, which contain lithium cobalt oxide, lithium hexafluorophosphate, organic carbonate, carbon materials, copper, aluminum and other chemical substances.
Li-ion battery pack customization is different from mass-produced products. It is independently developed and designed for different products. Therefore, in the process of customization, a certain fee must be paid (generally involving mold opening costs, development costs, and product proofing costs).
Research and development time: The length of research and development time is directly related to the new time of the product. The general research and development time of lithium-ion battery pack customization is about 30 days, and the fast research and development channel is implemented. Generally, the proofing time of products that do not need to be opened can be shortened to 15 days. ;
