Nanocomposite Polymer Electrolytes
Abstract
Solid-state, high-density, rechargeable batteries are key to the development of several military and commercial applications, from portable electronics to electric vehicles to back-up power sources in aircraft. The objective of this program is to develop and evaluate a new generation of nanocomposite electrolytes for future military and commercial applications. One interesting class of nanocomposite electrolytes is made by intercalating polymers such as PEO between the individual layers of a layered host such as a layered silicate (Fig. 1). The resulting materials combine relatively high ambient conductivity with single ion conduction characteristics. (Note that in these nanocomposite electrolytes, 1 nm thick, negatively-charged silicate layers are separated by interlayers, which contain charge-compensating Li-cations and polymer chains. Because of their massive lateral dimensions, the silicate anions are immobile.)
