To overcome the poor mechanical properties of polymer and gel polymer type electrolytes, microporous membranes impregnated with gel polymer electrolytes, such as PVdF. PVdF—HFP. and other gelling agents, have been developed as an electrolyte material for lithium batteries.Gel coated and/ or gel-filled separators have some characteristics that may be harder to achieve in the separator-free gel electrolytes. For example, they can offer much better protection against internal shorts when compared to gel electrolytes and can therefore help in reducing the overall thickness of the electrolyte layer. In addition the ability of some separators to shutdown... 

As a favorable separator, the microporous polyolefin membranes are required to absorb liquid electrolyte quickly in the electrolyte filling operation and retain the liquid electrolyte permanently for long-term operation of battery. Unfortunately, considerable difference in the polarity (dielectric constant) between the polyolefin... 

The subsequent investigations are focused on the filling state of the micropores in the PMMA membrane, whereas the preceding chapter referred to residues at the bottom of the micropores. Micropores have to be filled by electrolyte for their intended application as ion channel biosensor. The available imaging techniques revealed variations among the pore volumes after admission of electrolyte, but...
