Research Interest

My main research interests are in ion conducting polymers for possible applications in lithium batteries. I mainly study local structures in the amorphous phases in these polymer-salt systems. Here, the local structures means, the different ionic species present and the polymer conformations. I also study the conductivity enhancement of polymer electrolytes with ceramic fillers.
