Mar 25 2025The formation process plays an important role in enabling lithium batteries to achieve optimal performance and improving battery capacity, cycle life and safety.
Formation is the process of charging the lithium battery for the first time after it has been placed aside and filled with liquid to activate the positive and negative electrode materials inside and form a solid electrolyte membrane. In the production process of lithium batteries, formation is a very important process and has a significant impact on the performance of lithium batteries.
1. Capacity
Through reasonable formation, the lithium battery materials can be fully activated, the effective capacity can be improved, and the energy density and endurance of lithium batteries can be increased.
2. Cycle life
The appropriate formation process can improve the internal structure of lithium batteries, reduce electrode material loss and polarization, and extend the cycle life of lithium batteries.
3. Safety performance
It can improve the internal structure and interface characteristics of lithium ions, reduce the risk of thermal runaway, improve the safety performance of lithium batteries, and reduce the occurrence of problems such as short circuits and overheating.
4. Internal resistance
A reasonable formation process can optimize the structure of lithium battery materials and electrolyte permeability, reduce internal resistance, and thus improve the discharge efficiency and power performance of lithium batteries.
