Recent trends in ionic conductors

[DPSingh]

What are the new and undeveloped ( or which have much opportunities for young researchers in this area) areas which are getting attention of researchers these days, in solid fast ion conductors or related areas. I am seeing, a lot of work has already been done in this area, particularly , fast ion conducting glasses doped with silver and lithium halides, glass ceramics, composite electrolytes etc. Sometime I get frustrated why I had chosen this area for my PhD.Thousands of publications are there  in this area, and publishing a paper in good journals is really very tough.I need comments/suggestions from people who have long research experience in this field.

If you figure out how to make an easy wet synthesis of a yolk-shell out of a Li-ion conducting ceramic material that is stable in presence

of organic electrolytes used in Li-ion cells,  this would revolutionize the battery industry (which is getting a lot of attention and funding

at the moment).

The shells I am talking about are described here:

...but they did not make them out of a good Li-conducting material yet. If it would be made out of a good Li-ion conductor (that is inpenentrable

to solvent), cells would have virtually infinite cycleability and you could use much more agressive cathode / anode materials therefore increasing battery energy. This is a huge are of research, basically starting.

Li-ion conducting ceramics like LIPON have been already used in thin-film batteries, but they are spattering deposited and therefore

expensive. Wet synthesis of LIPON in form of shells with something inside would be one of the best solution but anything else with decent

Li+ conductivity would work as well.
