An often-overlooked aspect of materials development for batteries is the separator. The main purpose of the separator is to prevent electrical and physical contact between the electrodes while its porous structure allows an electrolyte (typically liquid) to transport ions. Conventionally, the separator is therefore a passive component.
In addition, the transferability of competencies from the production of lithium-ion battery cells is discussed. The publication “Battery Module and Pack Assembly Process” provides a comprehensive process overview for the production of battery modules and packs. The effects of different design variants on production are also explained.
It is envisaged that the link between fiber shape and separator performance may be established to give a design foundation for preparing paper-based separators for LIBs. Lyocell fibers used in lithium battery separators were mostly handled by fibrillating them in a grinder, which produces fibers with great porosity.
