Recently, much effort has been devoted to the development of battery separators for lithium-ion batteries for high-power, high-energy applications ranging from portable electronics to large-scale energy storage for power grids.
Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
Polyolefin-based lithium-ion battery separators generally exhibit poor wettability and low porosity, which hamper their ability to preserve electrolyte solution, thus adversely impacting battery performance because it correlates with ionic transport.
As for LFP batteries, both wet and dry separators are used by cell manufacturers. Although in the beginning wet separators was more common in LFP, the demand for more affordable cells has become the key factor that driving manufacturers to opt for dry separators.
Multifunctional separators offer new possibilities to the incorporation of ceramics into Li-ion battery separators. SiO 2 chemically grafted on a PE separator improves the adhesion strength, thermal stability (<5% shrinkage at 120 °C for 30 min), and electrolyte wettability as compared with the physical SiO 2 coating on a PE separator .
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.
