Abstract

Nanocomposites have opened the door to energy storage mechanisms not deemed possible a decade ago. For four decades, metal fluorides, due to their theoretical high energy densities, have been seen as a path towards high energy density batteries. This goal was quite elusive due to the high bangdgap and insulative character of these materials. Six years ago we introduced the use of nanocomposites to enable the theoretical voltage and capacities of a variety of metal fluorides and oxyfluorides. These metal fluorides operate on a reversible conversion mechanism enabling very high capacities in excess of 2X of today's state of the art. Such processes open the door questions regarding the non intuitive transport processes which enable the conversion and more importantly the reconversion process. This paper will be an overview of the work our group has accomplished in this area specifically regarding the optimization of performance, mixed conducting interphases and the large number of challenges that still remain to be overcome before successful implementation of this technology can be achieved.
