Description
Vynález se týká složení porézního nosiče aktivních hmot pro elektrochemické zdroje proudu.The present invention relates to a composition of a porous active material carrier for electrochemical power sources.
Jedním-ze způsobů výroby elektrod pro elektrochemické zdroje proudu je impregnace porézních nosičů elektrochemicky aktivními látkami. Porézní nosiče se obvykle zhotovují ve formě desek nebo pásů o tloušťce 0,2 až 0,3 mm a v některých případech bývají vyztuženy perforovaným pleohem nebo kovovou tkaninou. Nosiče se nejčastěji zhotovují z niklu, železa, mědi, zlata, stříbra nebo titanu, může však být použito i jiných elektricky vodivých materiálů. Celková pórovitost nosičů bývá nej častěji 60 až 85 %. Velikost pórů bývá vyjadřována nejčastěji jejich efektivním průměrem, který se zjišťuje například metodou vysokotlaké rtuťové porozimetrie.One method of producing electrodes for electrochemical power sources is to impregnate porous carriers with electrochemically active substances. The porous supports are usually made in the form of sheets or strips having a thickness of 0.2 to 0.3 mm, and in some cases are reinforced with perforated skin or metal fabric. The supports are most often made of nickel, iron, copper, gold, silver or titanium, but other electrically conductive materials may also be used. The total porosity of the carriers is most often 60 to 85%. Pore size is usually expressed by their effective diameter, which is determined, for example, by high pressure mercury porosimetry.
Předmětem vynálezu je porézní nosič aktivních hmot pro elektrochemická zdx*oje proudu, jehož podstata spočívá v tom, že objemový podíl pórů o efektivním průměru 1/un až 20>im je nejméně 70 % celkového objemu pórů. ’The subject of the invention is a porous active material carrier for electrochemical current flow, characterized in that the pore volume of an effective diameter of 1 / 20-20 µm is at least 70% of the total pore volume. ’
Pokrok dosažený vynálezcem proti stávajícímu stavu spočívá v tom, že na základě vývojových prací byl stanoven poměrně nízký rozsah velikostí pro efektivní průměr pórů v nosičích, při němž užitná vlastnosti elektrod jsou optimální.The progress made by the inventor over the prior art is that, based on developmental work, a relatively small size range has been determined for the effective pore diameter in the carriers, wherein the utility properties of the electrodes are optimal.
Řešení podle vynálezu předpokládá použití nosičů, u kterých objemový podíl pórůThe solution according to the invention envisages the use of carriers in which the pore volume fraction

198 533 o efektivním průměru 1/im je minimálně 70 % oelkového objemu všech pórů nosiče. Elektrody zhotovená z takových nosičů poskytují největší životnost, kapacitu a proudová odběry.198 533 having an effective diameter of 1 µm is at least 70% of the total pore volume of all pores of the support. Electrodes made of such carriers provide the greatest durability, capacity and current consumption.
