Battery cell formation, a crucial process, consists of two stages: pre-formation and main formation. It involves a controlled low-current charge to transition lithium-ion battery cells from raw materials into a stable and efficient electrochemical system. The goal of this process is to achieve a secure and effective transformation.
The inside of a lithium battery contains multiple lithium-ion cells (wired in series and parallel), the wires connecting the cells, and a battery management system, also known as a BMS. The battery management system monitors the battery’s health and temperature.
Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10]. Although there are different cell formats, such as prismatic, cylindrical and pouch cells, manufacturing of these cells is similar but differs in the cell assembly step.
Connecting lithium battery terminals properly is vital for optimal performance. There are a few key steps in the process: Terminals must form high-conductivity connections to the internal battery cell electrodes. Common methods include: Welding: Small spot welds fuse the terminal to the cell. Requires precision but creates durable connectivity.
The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.
Working Principle of Lithium-ion Batteries The primary mechanism by which lithium ions migrate from the anode to the cathode in lithium-ion batteries is electrochemical reaction.
