Abstract

The invention pertains to electrical engineering and can be used in the manufacture of metal-plated polymer fibre electrode substrates for use in chemical current sources. The aim of the invention is to allow the substitution of less scarce materials for palladium and tin during the operations preceding the chemical metal plating of the polymer fibre material. This is achieved by using a cation-exchanging material with a cation exchange capacity of 0.5 - 6 mg. equ./g as the fibrous material, and, before the metal plating process, saturating the polymer material with nickel ions and treating it with an aqueous solution of an alkali metal borohydride.

Description

Oblasť technikyTechnical field

Tento vynález sa všeobecne týka spôsobu výroby elektród pre chemické zdroje elektrickej energie, hlavne pre elektródy akumulátorov. Konkrétnejšie sa vynález týka spôsobu výroby takýchto elektród, ktorých základom je polymérny materiál. Vynález sa týka aj elektród vyrobených týmto spôsobom.The present invention relates generally to a method for producing electrodes for chemical power sources, particularly for battery electrodes. More particularly, the invention relates to a method for producing such electrodes based on a polymeric material. The invention also relates to electrodes produced in this way.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Súčasný stav techniky pozná elektródy na báze polyméru pre chemické zdroje elektrickej energie. Ako príklad je možné uviesť francúzsku patentovú prihlášku č. 2 472 842 z roku 1981. Podlá tejto prihlášky je elektróda vyrobená s kovom pokrytého substrátu, ktorý je potiahnutý aktívnym materiálom.The prior art recognizes polymer-based electrodes for chemical power sources. By way of example, French patent application no. No. 2,472,842 of 1981. According to this application, the electrode is made of a metal-coated substrate coated with an active material.

Jeden zo skôr známych spôsobov výroby takýchto elektród zverejnený v nemeckom patente č. 4 004 106 z roku 1991 spočíva v predbežnej aktivácii substrátu zhotoveného z polymérnych materiálov, hlavne z netkanej siete polyolefinových vlákien, v roztoku obsahujúcom cín a paládium, a v nasledujúcom pokovovaní prostredníctvom chemického a elektrolytického poniklovania.One of the previously known methods for the production of such electrodes disclosed in German patent no. No. 4,004,106 of 1991 consists in pre-activating a substrate made of polymeric materials, in particular a nonwoven web of polyolefin fibers, in a solution containing tin and palladium, and subsequent plating by chemical and electrolytic nickel plating.

Tento známy spôsob výroby elektród na báze polyméru má však mnoho nevýhod, ktoré sú spôsobené predovšetkým použitím ohromného množstva velmi drahého paládia na aktiváciu vláknitého polymérneho materiálu s velkou plochou povrchu.However, this known method of manufacturing polymer-based electrodes has many disadvantages, which are mainly due to the use of an enormous amount of very expensive palladium to activate the fibrous polymer material with a large surface area.

Naviac nasledujúca tvorba kovovej vrstvy na takto pripravenom materiáli bude mať pravdepodobne za následok preniknutie častíc paládia z povrchu polyméru do roztoku na pokovovanie, čo má za následok rozloženie roztoku.In addition, subsequent formation of a metal layer on the material thus prepared is likely to result in the penetration of the palladium particles from the polymer surface into the plating solution, resulting in the decomposition of the solution.

Podstata vynálezuSUMMARY OF THE INVENTION

Základným predmetom tohto vynálezu je zaistenie nového spôsobu výroby elektród na báze polyméru, kde nie je potrebné použiť drahé materiály. Tento cieľ sa dosiahne vďaka tomu, že je prvýkrát navrhnuté použitie vláknitých materiálov s katiónovou výmenou, ktoré zatiaľ na tento účel neboli použité. To umožňuje aktiváciu povrchu nasýtením iónmi rovnakého kovu, t.j. niklu, ktorým sa substrát potom pokovuje.It is an object of the present invention to provide a novel process for the production of polymer-based electrodes where expensive materials are not required. This is achieved by the first proposed use of cation exchange fibrous materials which have not been used for this purpose. This allows surface activation by saturating with the same metal ions, i. nickel by which the substrate is then metallized.

Vcelku je spôsob výroby elektród založených na tomto vynáleze nasledovný. Zoberie sa vláknitý polymérny materiál, ktorý má kapacitu katiónovej výmeny od 0,5 do 6,0 mg-ekv/g. Predtým sa môže na materiál pôsobiť hydrogénuhličitanom sodným.All in all, the method for producing electrodes based on the present invention is as follows. A fibrous polymer material having a cation exchange capacity of 0.5 to 6.0 mg-eq / g is collected. Previously, the material may be treated with sodium bicarbonate.

Ako zdroje iónov niklu môže byť použitý roztok síranu nikelnatého, v ktorom sa polymér ponechá na čas, ktorý stačí na to, aby bol materiál nasýtený iónmi. Hneď na to necháme na materiál aktivovaný iónmi niklu pôsobiť počas 0,5 až 30 minút vodným roztokom tetrahydroboritanu alkalického kovu s koncentráciou 0,1 až 1,2 g/1 pri teplote 15 až 70 °C. Výsledkom je redukcia sorbovaného niklu.As a source of nickel ions, a nickel sulfate solution can be used in which the polymer is left for a time sufficient to saturate the material with ions. Immediately thereafter, the nickel-ion-activated material is treated for 0.5 to 30 minutes with an aqueous alkali metal borohydride solution having a concentration of 0.1 to 1.2 g / l at a temperature of 15 to 70 ° C. The result is a reduction in the sorbed nickel.

Potom sú takto spracované polovýrobky poniklované zvyčajnými chemickými a elektrolytickými pokovovujúcimi technikami.Thereafter the semi-finished products are nickel-plated by conventional chemical and electrolytic plating techniques.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Podstata tohto vynálezu tu bude objasnená na nasledujúcom príklade.The essence of the present invention will be illustrated by the following example.

Príklad 1Example 1

Ako polymérny vláknitý materiál s katiónovou výmenou sa použije netkaná vpichovaná plsť založená na radiáciou očkovanom polypropyléne s kapaciotu iónovej výmeny 5 mg-eq/g vzhľadom na nikel, s priemerom vlákna 36 mikrónov, 87 % pórovitosťou a hrúbkou 5 mm. Uvedený materiál sa ponorí do 2 % vodného roztoku hydrogénuhličitanu sodného, kde sa hodinu ponechá a hneď potom sa premyje deionizovanou vodou a nasýti iónmi niklu reakciou s 3 % roztokom síranu nikelnatého počas pol hodiny. Akonáhle sú niklom nasýtené polotovary (predrobky) premyté, nechajú sa pri 30 °C 15 minút reagovať s roztokom tetrahydroboritanu sodného s koncentráciou 0,5 g/1.The cation exchange polymeric fibrous material used is a nonwoven needled felt based on radiation-grafted polypropylene with an ion exchange capacity of 5 mg-eq / g relative to nickel, with a fiber diameter of 36 microns, 87% porosity and a thickness of 5 mm. The material was immersed in a 2% aqueous sodium bicarbonate solution, where it was left for one hour, and then washed with deionized water and saturated with nickel ions by treatment with a 3% nickel sulfate solution for half an hour. Once the nickel-saturated preforms are washed, they are reacted at 30 ° C for 15 minutes with a 0.5 g / l sodium borohydride solution.

Po skôr opísanom spracovaní sa stanú predrobky tmavo šedé. Takto aktivované predrobky sú chemicky poniklované pri izbovej teplote v roztoku nasledujúceho zloženia, v g/1:After the treatment described above, the blanks become dark gray. The thus-activated preforms are chemically nickel-plated at room temperature in a solution of the following composition, in g / l:

síran nikelnatý - 50 chlorid amónny - 35 fosfornan sodný - 40 amoniak - do pH = 9.nickel sulphate - 50 ammonium chloride - 35 sodium phosphate - 40 ammonia - up to pH = 9.

Potom sú predrobky poniklované v štandardnom Wattovom elektrolytickom pokovovacom článku, až sa dosiahne obsah niklu 0,5 g/cm3. Vlastnosti bázy takto vyrobenej elektródy sú ďalej uvedené v tabuľke.Then, the preforms are nickel-plated in a standard Watt electrolytic plating cell until a nickel content of 0.5 g / cm 3 is reached. The base properties of the electrode so produced are shown in the table below.

Kvôli porovnaniu zahrňuje tabuľka tiež vlastnosti materiálu používaného ako elektródová báza firmou Norreske.For comparison, the table also includes the properties of the material used as an electrode base by Norreske.

Parameter parameter Hodnota parametru Parameter value Elektródová báza podľa príkladu 1 Electrode base according to Example 1 Elektródová báza podľa Norreske Electrode base by Norreske Pórovitosť, % Povrchová hmotnosť, Porosity,% Surface weight, 84,1 84.1 83,4 83.4 cm2/gcm 2 / g 280 280 221 221 Hrúbka pokovovania, Plating thickness, mikróny micron 3,8 3.8 5,2 5.2 Stredný priemer, Medium diameter mikróny micron 150 150 134 134 Stredný priemer vlákien, mikróny Medium diameter fibers, microns 46,5 46.5 38,5 38.5

Z uvedenej tabuľky vyplýva, že v základných a najdôležitejších vlastnostiach sa elektróda zhotovená podľa vynálezu veľmi približuje k elektróde zhotovenej Norreskom.The above table shows that, in the basic and most important properties, the electrode made according to the invention is very close to the electrode made by Norresco.
