Freudenberg developed its Battery Pack Liquid Absorbers as absorbent pads that can reliably take up and store large volumes of liquid. The modular design allows for scaling of the absorption capacity, which is limited only by the available space. Customer-specific geometries can even be implemented thanks to the flexible material.
In addition, the separator must be quickly immersed in electrolyte to facilitate battery assembly during large-scale production. Note that electrolyte absorption by the separator depends on the hydrophilicity and crystallinity of the polymer matrix, as well as the porosity of the membrane [ 112 ].
The thinner the membrane, the lower the mechanical strength, increasing the risk of internal short circuits during long-term use due to perforation and battery assembly [ 24 ]. Conversely, thicker separators could raise resistance, thus lowering the electrochemical performance of the battery.
Also, the cycling stability and rate capability of the battery separator are both examined by assembling the electrolyte-soaked separator between two symmetrical lithium electrodes, and the initial LIBs should display high cycling stability and capability [ 136, 142 ].
The separator, an indispensable part of lithium-ion batteries (LIBs), plays a vital role related to the safety and electrochemical performance of these batteries because its thermal stability, mechanical properties, and ionic conductivity directly influence the performance and safety of LIBs.
Separators are an essential part of current lithium-ion batteries. Vanessa Wood and co-workers review the properties of separators, discuss their relationship with battery performance and survey the techniques for characterizing separators.
