Abstract
A highly conductive polymer based solid gel membrane is disclosed. The membrane is especially well suited for use in such electrochemical devices as, for example, aluminum/air, zinc/air, Zn/MnO , Ni/Cd and hydrogen fuel cells, as well as in electrochromic devices such as smart windows and flat panel displays. In accordance with the principles of the invention, anion- and cation-conducting membranes are formed. The gel composition of the membrane contains the ionic species within its solution phase such that the species behaves as in a liquid electrolyte, while at the same time, the solid gel composition prevents the solution phase from diffusing into the device. Methods of forming polymer based solid gel membranes of the present invention are also disclosed.
