The filling consists of several dosing steps of electrolyte liquid into the cell and the subsequent (intermediate) wetting of the cell components. The quantity of electrolyte filled not only has an impact on the wetting rate of electrodes and separator but also limits the capacity of the cell and influences the battery lifetime.
Filling of the electrode and the separator with an electrolyte is a crucial step in the lithium ion battery manufacturing process. Incomplete filling negatively impacts electrochemical performance, cycle life, and safety of cells.
The production of lithium-ion batteries (LIBs) is crucial for advancing energy-storage technologies, yet uncertainties remain regarding key influencing factors along the process chain. Specifically, the electrolyte filling process is critical for optimal cell performance.
However, the filling process consists not only of an initial filling phase but also of a subsequent long wetting phase. In practice, even after the standard amount of electrolyte has been fully injected into the battery, the electrolyte does not completely wet the entire battery structure.
