r03 battery

　　r03 battery production process flow.

　　Lithium battery production process flow:

　　The first step - preparation of electrode slurry

　　Mainly, the electrode active materials, binders, solvents, etc. are mixed together and thoroughly stirred and dispersed to form a slurry.

　　The second step - coating

　　Evenly apply the slurry prepared in the first step to the current collector (aluminum foil or copper foil, etc.) with a specified thickness, and dry the solvent.

　　Step 3 - Pole piece punching

　　Cut the pole piece made in the previous step into the specified size and shape.

　　Step 4 - Lamination

　　Assemble the positive and negative electrode sheets and separator together, and after completing the glue application, the electrode core is formed.

　　Step 5--Assemble the soft pack battery

　　Put the pole core produced in the previous step into the aluminum-plastic film that has been punched out, and complete top sealing, side sealing, etc. (leaving a hole for liquid injection) to form a soft-pack battery that has not been filled with liquid.

　　Step 6 - Injection

　　Inject the specified amount of electrolyte into the soft-packed battery cell. Of course, the battery core must be baked and filled with liquid in a low-humidity environment. Excessive moisture content is not good.

　　Step 7--Battery sealing

　　The gas inside the cell is extracted and sealed in a vacuum environment.

　　The result of the lithium battery front-end process is to prepare the positive and negative electrode sheets of the lithium battery. The first step is stirring, that is, mixing the positive and negative solid-state battery materials evenly, adding the solvent, and stirring them into a slurry through a vacuum mixer. The mixing of ingredients is the basis for the subsequent lithium battery process, and high-quality stirring is the basis for the high-quality completion of the subsequent coating and rolling processes.

　　With the rapid development of electric vehicles and automobiles, the power sources on the vehicles have also developed rapidly. However, there are many problems in the production of batteries, which has caused the quality of battery products in the market to be very uneven, and the battery capacity and cycle life are very uneven. The failure to achieve the designed service life has a lot to do with the unique production process of the battery during production. The structure of the battery consists of outer casing, upper cover, polar plates, separators, busbars, poles, bridge protection plates, terminals and other components.

　　Unscrew the exhaust plug and be sure to penetrate the ventilation hole on the plug. There is a sealing gasket and sealing paper under the plug, which need to be removed after filling with acid;

　　The electrolyte temperature must be cooled to below 30°C and poured into the battery;

　　Inject the prepared electrolyte into each cell. The liquid level of the plastic case battery should be flush with the max mark on the case. The liquid level of the rubber tank battery should be 10-15mm higher than the partition plate;

　　Tighten the exhaust plug to prevent acid leakage.
