摘要： An aprotic polymer/molten salt ternary mixture solvent and to a corresponding quaternary mixture additionally including an ionic conducting salt, which are prepared by mixing the constituents of the mixture. These mixtures are advantageously used in the preparation of electrochemical membranes, electrochemical systems and of electrochromic systems. Also, electrochemical and electrochromic systems obtained hereby that exhibit, in particular, excellent electrochemical properties at low temperatures.

摘要： A method of preparing an electrochemical electrode which is partially or totally covered with a film that is obtained by spreading an aqueous solution comprising a water-soluble binder over the electrode and subsequently drying same. The production cost of the electrodes thus obtained is reduced and the surface porosity thereof is associated with desirable resistance values.

摘要： There is provided a method of manufacturing nanoparticles comprising the steps of feeding a core precursor into a plasma torch in a plasma reactor, thereby producing a vapor of silicon or alloy thereof; and allowing the vapor to migrate to a quenching zone of the plasma reactor, thereby cooling the vapor and allowing condensation of the vapor into a nanoparticle core made of the silicon or alloy thereof, wherein the quenching gas comprises a passivating gas precursor that reacts with the surface of the core in the quenching zone produce a passivation layer covering the core, thereby producing said nanoparticles. The present invention also relates to nanoparticles comprising a core covered with a passivation layer, the core being made of silicon or an alloy thereof, as well as their use, in particular in the manufacture of anodes.
