Of cause, polymer eletrolyte can be applicable to Li-S battery and Li-air battery. You may find some papers (published in between 2000~2006 for Li-S and 2009~2011 for Li-air) on the use of Poly(ethylene oxide) based polymer electrolyte for Li air and Li sulfur batteries. However, for the two next generation batteries, major electrolyte issues are not on the immobilization of electrolyte phase (by employing polymer electolyte) but on whether electrolyte is compatible to sulfur and air electrochemistry. It could be answer to your inquiry. The reversibilities of sulfur and air are not enough for commercial applications, and therefore, the development of new electrolyte for enhanced reversibility is of critical importance. If one can explore new concept which addess the current problems of Li sulfur and air batteries with using new polymer electrolyte, it would attract interest.

yes. there are many publications describing the application of polymer electrolytes for Li-S. Scrosati was a strong believer in this. You can read the recent chem review on Li-S by Manthiram.
