Abstract: The present invention relates to electrolyte formulations comprising at least one compound comprising a dihydridodicyanoborate anion and their use in an eletrochemical and/or optoelectronic device such as a photovoltaic cell, a light emitting device, an electrochromic or photo-electrochromic device, an electrochemical sensor and/or biosensor, preferably their use in a dye or quantum dot sensitized solar cell.

Abstract: The invention relates to new compounds containing alkyl-alkoxy-cyano-borate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Abstract: The invention relates to new compounds containing alkyl/alkenyl-cyano-borate or alkyl/alkenyl-cyano-fluoroborate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Abstract: The present invention relates to compounds containing hydrido-tricyano-borate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Abstract: The present invention relates to the use of at least one tertiary amine-N-oxide of formula I as additive in dye-sensitized solar cells and to special electrolyte formulations and a dye-sensitized solar cell comprising at least one compound of formula I.

Abstract: The invention presents a method for manufacturing an IC card with a built-in battery where the seal of the battery does not breakdown during a heating and laminating process. The manufacturing method for the IC card of the invention includes accommodating a thin type battery 1 in a cavity 79 formed by overlaying an inner sheet 73 and a first oversheet 74 on a core sheet 72 having a penetration pole 79a. A second oversheet 75 covers the cavity 79, and a spacer 25 is inserted between a seal section 11 of the thin type battery 1 and second oversheet 75. Pressure and heat are applied to mutually adhere the sheets, wherein the pressing force is applied to the seal section 11 by way of the spacer 25.

Abstract: In a lithium cell using lithium foil or lithium alloy foil as an anode active substance, the main surface of an anodic current-collecting plate in direct contact with the lithium foil or the lithium alloy foil is roughened by laser machining.
