Abstract
Abstract Cells utilizing halogen reactive materials such as organo-metallic polymers having the nominal stoichiometry [M(TTL)] x in which M is a transition metal containing complex having at least one transition metal ion, TTL has the nominal atom composition C 10 H 4 X 4 and substituted compositions thereof in which X is selected from the group consisting of S, Se, Te and mixtures thereof, and x is equal to or greater than 1 are described.
