Free QuoteFilling a lithium-ion battery with electrolyte liquid is a core process in battery manufacturing. Better understanding of this process will reduce costs while enabling high product quality. Nonetheless, the process has not been sufficiently examined by science yet.
The electrolyte filling process aims to dose the necessary amount of electrolyte into the battery within the shortest possible time. In general, the voids of the cell stack are not completely filled after electrolyte dosing. To allow the liquid to penetrate the porous media completely, the cells are warehoused.
This way, the process model assists the user in designing an electrolyte filling process for a random battery. The proposed implementation of the filling process serves as a base for the design of the filling apparatus.
Conclusions The electrolyte filling, as a bottleneck within the process chain of battery production, is characterized by long throughput times and a high cost of experimental studies required to ramp up stable and optimized processes.
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.
One critical manufacturing step is the filling of the cell with liquid electrolyte [3, 4]. Despite its crucial importance for battery quality and costs, this process has not been sufficiently studied by science yet. The electrolyte liquid enables ion exchange between the electrodes.
