The process technology of lithium-ion batteries is very strict and complex. We can only briefly present some of the main processes here. ? (1) Mud? Use special solvents and binders to mix the powdered positive and negative active materials respectively, and stir them evenly at high speed to obtain slurry-like positive and negative materials. (2) Coating film: Apply the prepared suspension evenly to the surface of the metal foil, dry it, and make positive and negative electrode plates respectively. ? (3) Assembly? Place the positive electrode sheet - separator - negative electrode sheet - separator in order from top to bottom, then roll it into the battery pole core, then inject the electrolyte, sealing and other processes to complete. process of assembling batteries into finished batteries. (4) Training: use equipmentSpecial battery charge and discharge ent to conduct charge and discharge tests on finished batteries, test each battery, and select qualified finished batteries before leaving the factory.
The second is to assemble the lithium battery pack (also called PACK) by testing the cells, which can be used in electric vehicles, street lights, miner's lamps, etc. If you do this kind of business, the investment is low and it is relatively simple. You can start with just 10,000 yuan. .....
These three types of batteries have their own advantages and disadvantages, it depends on what you understand or focus on.
Lithium manganese oxide battery has relatively small capacity, good safety and low price;
Lithium iron phosphate battery has moderate capacity, good safety and a low price;
>BatteriesTernary batteries have higher capacity, are generally safe, and are more expensive;
Miner's lamp batteries are expected to involve major issues such as safety and service life. You can choose between the first two.
