  What is the production process of 18650 lithium battery?

  The production process of 18650 lithium battery cells. Common 18650 lithium batteries are divided into lithium ion batteries and lithium iron phosphate batteries. Li-ion battery voltage is nominal voltage 3.7v, charge cut-off voltage is 4.2v, lithium iron phosphate battery nominal voltage is 3.2V, charge cut-off voltage is 3.6v,

The nominal voltage of lithium-ion battery is 3.7v, the charge cut-off voltage is 4.2v, the nominal voltage of lithium iron phosphate battery is 3.2V, the charge cut-off voltage is 3.6v, the capacity is usually 1200mAh-3350mAh, and the common capacity is 2200mAh- 2600mAh.

  18650 lithium battery production process

  The 18650 lithium battery is a lithium-ion battery commonly used in electronic products, and is often used as a battery cell in a laptop battery. The meaning rule of its model is: For example, 18650 type refers to a cylindrical battery with a diameter of 18mm and a length of 65mm.

  18650 lithium battery production process 1: coating

  First of all, from the understanding of the coating process, large rolls of copper foil (yellow) and aluminum foil (silver) can be seen in this process. Aluminum foil is used to coat nickel-cobalt-manganese NCM ternary material; on the contrary, copper foil is used to coat graphite as the negative electrode active material; the white one is the diaphragm. The global lithium-ion battery separator is mainly occupied by manufacturers such as Asahi, Celgard, SK, toray, and W-SCOP. These foreign companies control nearly 70% of the market share. The market share of my country's separator companies is about 30%, and the independent localization of lithium-ion battery separators is constantly breaking through. The capacity of the battery cell is obtained according to the proportion area of these formulas.

  A whole roll of coated positive and negative electrode materials is about 126mm wide, and then cut into 7 small rolls with a width of about 18mm. Each roll will be evenly divided into several sections, and each section represents the material required for a battery cell. According to Xu Gong, an engineer at the cell factory, the current price of ternary cathode materials is 120,000 yuan per ton, and each ton of material can be used to produce 50,000 cells; the current average daily output of cells is 500,000, and 10 tons are needed The cost of ternary cathode materials alone is 600,000 yuan per day.

  The automated machine stamps each segment with nickel strips and insulating high-temperature-resistant Mylar sheets (Mylar), and then weighs them in five levels, namely heavy, A1, A2, A3, and light. This is the same as the selection of CPU wafers. The same batch of cutting processes will also have different physiques. According to different physiques, the corresponding capacities will be divided and shipped in pairs.

  18650 lithium battery production process two: assembly

  The sorted positive and negative electrodes will be fully automatic packaged here, and the white material is the diaphragm. The 18650 lithium battery can't work normally. It needs to add electrolyte as a medium to let the positive and negative electrodes undergo a chemical reaction, so that lithium ions can migrate between the positive and negative electrodes, and the lithium ion battery can be charged and discharged only when the charged ions output energy. After the automatic roll is wrapped, it rolls directly on the assembly line, and enters the next assembly step to be loaded into the steel shell.
