1. Sludge making: Use special solvents and binders to mix powdered positive and negative active materials, respectively. After uniform stirring, positive and negative slurry-like materials are made.
2. Coating film: The positive and negative electrode slurries are evenly coated on the surface of the metal sheet through an automatic coating machine, and then automatically cut into positive and negative electrode pieces after automatic drying.
3. Assembly: In the order positive electrode sheet - separator - negative electrode sheet - separator from top to bottom, the battery is assembled by electrolyte injection, sealing, welding of positive and negative electrode tabs, etc. ., to complete the battery assembly process to make the finished battery.
4. Training: Place the finished batteries into the test cabinet for testingcharging and discharging, and select qualified finished batteries before leaving the factory.
Detailed Information
Lithium batteries are widely used in energy storage systems such as hydropower, thermal power, wind and solar power plants, uninterruptible power supplies. for post and telecommunications, and power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.
Lithium-ion batteries have been widely used in portable devices such as laptops, cameras and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery has been tested in electric vehicles and will become one of the main power sources for electric vehicles in the 21stcentury and will be used in satellites, aerospace and energy storage.
With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of lithium battery industry.
