A composition, method of its preparation, and zinc electrodes comprising the composition as the active mass, for use in rechargeable electrochemical cells with enhanced cycle life is described. The electrode active mass comprises a source of electrochemically active zinc and at least one fatty acid or a salt, ester or derivative thereof, or an alkyl sulfonic acid or a salt ester or derivative thereof. The zinc electrode is assumed to exhibit low shape change and decreased dendrite formation compared to known zinc electrodes, resulting in electrochemical cells which have improved capacity retention over a number of charge/discharge cycles.

Radiofrequency attenuator and method. The attenuator includes a pair of transparent windows. A chamber between the windows is filled with molten salt. Preferred molten salts include quarternary ammonium cations and fluorine-containing anions such as tetrafluoroborate (BF), hexafluorophosphate (PF), hexafluoroarsenate (AsF), trifluoromethylsulfonate (CFSO), bis(trifluoromethylsulfonyl)imide ((CFSO)N), bis(perfluoroethylsulfonyl)imide ((CFCFSO)N) and tris(trifluoromethylsulfonyl)methide ((CFSO)C). Radicals or radical cations may be added to or electrochemically generated in the molten salt to enhance the RF attenuation.

A single-compartment reversible mirror device having a solution of aprotic molten salt, at least one soluble metal-containing species comprising metal capable of being electrodeposited, and at least one anodic compound capable of being oxidized was prepared. The aprotic molten salt is liquid at room temperature and includes lithium and/or quaternary ammonium cations, and anions selected from trifluoromethylsulfonate (CFSO), bis(trifluoromethylsulfonyl)imide ((CFSO)N), bis(perfluoroethylsulfonyl)imide ((CFCFSO)N) and tris(trifluoromethylsulfonyl)methide ((CFSO)C). A method for preparing substantially pure molten salts is also described.
