Why is electrolyte filling a bottleneck in lithium-ion battery production?
The electrolyte filling process is considered one of the bottlenecks of lithium-ion battery production due mainly to the long electrolyte wetting times. Additionally, the required experimental process design is time and material-intensive, increasing the development costs of new materials or cell designs.
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.
What is filling a lithium-ion battery with electrolyte liquid?
Filling 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.
Is the electrolyte filling process valid for cell formats and parameter ranges?
The model accurately portrayed the impact of the inputs and matched the experimental data. The results show that the overall method for setting up and performing the simulations of the electrolyte filling process is valid for the studied cell formats and parameter ranges.
How can lithium-ion batteries meet consumer demands for electric transportation?
Author to whom correspondence should be addressed. In order to meet consumer demands for electric transportation, the energy density of lithium-ion batteries (LIB) must be improved. Therefore, a trend to increase the overall size of the individual cell and to decrease the share of inactive materials is needed.
How can a non-destructive method reduce the production costs of Li-ion bat-Teries?
In order to reduce the production costs, there is a need for a non-destructive method with which the filling and wet-ting process can be visualized in situ during the production of the cell. The ultrasonic system developed at Fraunhofer IKTS (Figure 1) is used to monitor the wetting process of Li-ion bat-teries.
