02 Industry knowledge
Lithium iron phosphate (LiFePO4) is a commonly used cathode material in lithium-ion batteries. It exhibits excellent cycling stability, safety, and energy density, making it widely applied in the fields of energy storage and electric vehicles.
Below is an overview of the production process for lithium iron phosphate (LiFePO4) lithium-ion batteries:
Raw Material Preparation: The primary step in producing lithium iron phosphate batteries is to prepare the required raw materials, including lithium source, iron source, and phosphorus source.
Common lithium sources include lithium carbonate or lithium hydroxide. Iron sources can be iron salts, and phosphorus sources are typically phosphates.
Preparation of lithium iron phosphate: The appropriate amounts of lithium source, iron source, and phosphorus source are mixed in the proper proportions to form a homogeneous mixture. This mixture is then ground to obtain a fine slurry.
Afterward, the slurry is subjected to spray drying and sintering. At high temperatures, the compounds in the raw materials undergo reactions to form lithium iron phosphate.
Battery Preparation: The lithium iron phosphate powder is mixed with conductive additives (such as carbon black) and binders to form the cathode material of the battery.
The cathode material is coated onto a conductive current collector (such as aluminum foil) and then fixed onto the collector through pressing and heating steps.
Assembly and Packaging: The cathode sheet, separator soaked in lithium ion electrolyte, and anode sheet are stacked together to form the layered structure of the battery.
Then, the assembly is sealed using methods such as heat sealing or laser welding to ensure internal sealing of the battery and prevent electrolyte leakage.
Charging and Testing: The produced lithium iron phosphate batteries will undergo charging and discharging cycles to activate the batteries and test their performance.
During this process, capacity testing and cycle life testing can also be conducted on the batteries.
Please note that the above is just a general overview of the typical process for manufacturing lithium iron phosphate batteries. The actual manufacturing process may vary depending on the specific manufacturer and battery design.
The details and parameters of the process may also vary based on production scale and technical requirements. Furthermore, in order to improve production efficiency and battery performance, researchers and manufacturers are continually exploring and refining the process.
