Abstract: Polymeric ion conductors composed of a polymeric matrix associated with an isoindolinium moiety represented by Formula I as described in the specification are provided. Anion conducting compositions comprising an anion conducting polymer associated with, or threaded within and having mechanically interlocked therearound, a cyclic moiety are also provided. lonomeric materials, including, for example, ion exchange membranes such as anion exchange membranes, made of the polymeric ion conductor and/or the anion conducting composition, and electrochemical systems and articles-of-manufacturing containing the polymeric ion conductor, the anion conducting composition or the ion exchange membrane are also provided.

Abstract: Polymeric ion conductors composed of a polymeric or co-polymeric backbone which comprises a plurality of backbone units, a metal ligand attached to at least a portion of the backbone units, and a metal ion attached to the metal ligand are provided. The metal ligand can be an N-heterocyclic carbene ligand and the metal can feature low oxophilicity. lonomeric materials, including, for example, ion exchange membranes such as anion exchange membranes, made of the polymeric ion conductor, and electrochemical systems and articles-of-manufacturing containing the polymeric ion conductor or the ion exchange membrane are also provided.

Abstract: Anion exchange membrane electrode assemblies, fuel cells and electrochemical cells comprising such assemblies, which comprise an anion exchange membrane sandwiched between an anode compartment and a cathode compartment, and which are operable at a temperature of at least 100° C., are provided. Systems, devices, articles and methods that utilize such assemblies at an operating temperature of at least 100° C. are also provided.

Abstract: A thermal battery which comprises a number of stacked cells, each cell consisting essentially of an anode with a lithium compound, a lithium free pyrotechnic heat source pellet which includes a cathode precursor and an all lithium electrolyte layer separating between the anode and the pyrotechnic heat source pellet. Upon ignition of the heat source, an oxide of the cathode precursor is obtained which is lithiated by the lithium supplied by the all lithium electrolyte ion source.
