A system comprises a first electrode, an electrolyte membrane, and a second electrode. The first electrode is configured to reduce oxygen in a gas to an oxygen carrier ion at an intermediate temperature. The electrolyte membrane is configured to transport the oxygen carrier ion, and the second electrode is configured to oxidize the oxygen carrier ion to an oxygen molecule. Oxidation of the oxygen molecule consumes less than four electrons.

Provided is an ion-conducting layer including: an ion conductive matrix; and a 1D composite dispersed in the ion conductive matrix and oriented in a membrane thickness direction, in which the 1D composite includes a core of a non-conductive 1D nanostructure; an intermediate layer enclosing the core and having magnetic nanoparticles bonded to a surface thereof; and a surface layer conducting the same kind of ions as ions in the matrix.

The invention relates to a separator for non-aqueous-type electrochemical devices that has been coated with a polymer binder composition having polymer particles of two different sizes, one fraction of the polymer particles with a weight average particle size of less than 1.5 micron, and the other fraction of the polymer particles with a weight average particle size of greater than 1.5 microns. The bi-modal polymer particles provide an uneven coating surface that creates voids between the separator and adjoining electrodes, allowing for expansion of the battery components during the charging and discharging cycle, with little or no increase in the size of the battery itself. The bi-modal polymer coating can be used in non-aqueous-type electrochemical devices, such as batteries and electric double layer capacitors.

A proton conductor includes a complex of phosphoric acid and a coordination polymer in which a metal ion and a ligand are continuously connected by a coordinate bond. The phosphoric acid includes a first phosphoric acid that is coordinately bonded to the metal ion, and a second phosphoric acid that is not coordinately bonded to the metal ion.
