Description
Galvanisk primær- eller sekundærelement, hvor den positive elektrodes masse helt eller delvis består av sølv. Galvanic primary or secondary element, where the mass of the positive electrode consists wholly or partly of silver.
Det har allerede i lang-tid vært kjent å benytte sølv- eller sølvforbindelser, f.eks. sølvoksyd eller sølvklorid som1positiv elektrode i galvaniske primær- eller sekundærelementer. Anvendelsen av slike sølvforbindelser medfører den store fordel, at det kan frem-stilles galvaniske elementer, som kan lagre vesentlig større energi-mengder med samme volum og vekt enn det var mulig ved de elementer som frem til idag har hatt praktisk betydning. It has already been known for a long time to use silver or silver compounds, e.g. silver oxide or silver chloride as1 positive electrode in galvanic primary or secondary cells. The use of such silver compounds brings with it the great advantage that galvanic elements can be produced, which can store significantly larger amounts of energy with the same volume and weight than was possible with the elements that until today have been of practical importance.
På grunn av disse sølvforbindelsers relativt høye oppløselig-het i alkalisk elektrolytt opptrer imidlertid, ved den; praktiske anvendelse av positive, sølvelektroder store vanskeligheter, håa levetiden for slike elementer^angår. Sølvforbindelsens oppløselighet med-fører ved tilstedeværelsen av en negativ elektrode en vandring av kolloid oppløst sølv til katoden, og medfører derved ikke bare at separatoren tilstoppes, men også at separatoren.etter noen få opplad-nings- og utladningssykluser blir elektronledende på grunn av avleir-ingen av sølvpartikler, og man får derved en kortslutning av cellen. Due to the relatively high solubility of these silver compounds in alkaline electrolyte, however, it occurs; practical application of positive, silver electrodes great difficulties, as regards the lifetime of such elements. The solubility of the silver compound results in the presence of a negative electrode in the migration of colloidal dissolved silver to the cathode, thereby not only causing the separator to become clogged, but also for the separator to become electron-conductive after a few charge and discharge cycles due to deposits. none of the silver particles, and the cell is thereby short-circuited.
Det er gjort mange forslag for hvorledes man skal hindre en vandring av kollois oppløst sølv gjennom separatoren. Man har særlig forsøkt å oppnå dette ved å anvende forskjellige typer separatormateri-ale, som f.eks. ionebyttermembraner, semipermeable membraner eller regeherert cellulose. Many proposals have been made for how to prevent colloidal dissolved silver from migrating through the separator. One has particularly tried to achieve this by using different types of separator material, such as e.g. ion-exchange membranes, semi-permeable membranes or regenerated cellulose.
Alle disse forslag er forsøk på å holde de kolloidoppløste sølvpartikler fra å vandre gjennom separatoren ved hjelp av det an-vendte separatormaterials f ilter virkning, altså på "mekanis^måte. All these proposals are attempts to keep the colloidally dissolved silver particles from traveling through the separator by means of the filter effect of the used separator material, i.e. in a "mechanical" way.
I alle disse tilfelle førte bruken av ovennevnte separator-materiale med seg andre ulemper, spesielt en vesentlig økning av den indre motstand foruten problemet med å avstenge, en slik celle helt gass-tett. Derved ble imidlertid anvendelsesområdet for en akkumulator fremstilt på denne måte meget sterkt begrenset, rent bortsett fra at også de foran beskrevne separatormaterialer blir tilstoppet av de oppløste sølvpartiklér og at levetiden til en slik celle var vesentlig mindre enn den- for de tidligere kjente akkumulatorsystemer, som f.eks. nikkel-kadmium. In all these cases, the use of the above-mentioned separator material brought with it other disadvantages, in particular a significant increase of the internal resistance besides the problem of sealing off such a cell completely gas-tight. Thereby, however, the area of application for an accumulator manufactured in this way was very severely limited, purely apart from the fact that the separator materials described above are also clogged by the dissolved silver particles and that the lifetime of such a cell was significantly less than that of the previously known accumulator systems, which e.g. nickel-cadmium.
Oppfinnelsens oppgave, nemlig å forhindre at kolloid oppløst sølv vandrer gjennom separatoren, blir løst pa følgende måte. Man gikk ut fra den kjennsgjerning, at en slik sølvvandring bare kan finne sted når det er et elektrisk felt tilstede. For den positive sølvelektrode forsøkte man å «liminere det elektriske felt som vanligvis hersker i et galvanisk element, ved å sette inn en tilleggselektrode slik som vist i fig. 1. The task of the invention, namely to prevent colloidal dissolved silver from traveling through the separator, is solved in the following way. It was assumed that such silver migration can only take place when an electric field is present. For the positive silver electrode, an attempt was made to "eliminate the electric field that usually prevails in a galvanic element, by inserting an additional electrode as shown in fig. 1.
Man oppnår derved galvanisk primær- eller sekundærelement, hvor den positive elektrodes masse helt eller delvis består av sølv, This results in a galvanic primary or secondary element, where the mass of the positive electrode consists wholly or partly of silver,
og det anvendes en alkalisk elektrolytt som kan være kapillart oppsuget i porene til elektrodenes aktive masser og i den mellom elektrodene anordnet separator, og hvor det mellom den positive elektrode og separatoren er anordnet en tilleggselektrode, hvilket element er kjennetegnet ved at tilleggselektroden inneholder en aktiv masse, som i fullstendig oksydert tilstand har et elektrokjemisk potensial, som minst er lik det elektrokjemiske potensial for sølvoksyd. and an alkaline electrolyte is used which can be capillaryly absorbed into the pores of the active masses of the electrodes and in the separator arranged between the electrodes, and where an additional electrode is arranged between the positive electrode and the separator, which element is characterized by the fact that the additional electrode contains an active mass , which in a completely oxidized state has an electrochemical potential, which is at least equal to the electrochemical potential of silver oxide.
Figuren viser en akkumulator uten fri elektrolyttvæske, hvor elektrolytten på kjent måte holdes oppsuget i porene til elektrodene og separatoren ved hjelp av kapillarkrefter. Den positive sølvelektrode er betegnet med a, den negative elektrode med b, separatoren med c og tilleggselektroden med d. Tilleggselektroden d står i elektronkontakt med sølvelektroden a. The figure shows an accumulator without free electrolyte liquid, where the electrolyte is kept absorbed in the known manner in the pores of the electrodes and the separator by means of capillary forces. The positive silver electrode is denoted by a, the negative electrode by b, the separator by c and the additional electrode by d. The additional electrode d is in electron contact with the silver electrode a.
Når det elektrokjemiske potensial til tilleggselektroden d When the electrochemical potential of the additional electrode d
i fullstendig oksydert tilstand er likt eller høyere enn potensialet-' til sølvoksyd (AggO), så opptrer intet spenningsfall mellom deri positive elektrode a og den negative elektrode b, slik at de kolloidopp-løste sølvartikler ikke kan vandre i retning mot den negative elek.trode. in a completely oxidized state is equal to or higher than the potential of silver oxide (AggO), then no voltage drop occurs between positive electrode a and negative electrode b, so that the colloidally dissolved silver particles cannot migrate in the direction of the negative electrode. believed.
Hvis tilleggselektroden d overveiende, består av et elektrokjemisk virksomt materiale, som f.eks. nikkelhydroksyd, blir ved opplad-ningen av en innretning tilsvarende fig. 1, sølvelektroden a først oksydert til sølvoksyd (AggO). En videre oksydasjon til sølvperoksyd (AggQj) kan imidlertid ikke finne sted, da det elektrokjemiske potensial til NlpOj ligger mellom potensialene til AggO og <Ag>gOg, og tilleggselektroden d etter fullstendig oppladning allerede utvikler oksygen ved et potensial som ligger under det til AggOg. Da oppladningsstrømmen utelukkende fører til oksygenutvikling ved tilleggselektroden d, unngår man på en sikker måte dannelsen av sølvperoksyd også ved lengre over-oppladning. Dette er hensiktsmessig, når akkumulatoren skal benyttes i en situasjon som gjør det nødvendig med en jevn spenning under hele utladningsperioden. If the additional electrode d mainly consists of an electrochemically active material, such as e.g. nickel hydroxide, when charging a device corresponding to fig. 1, the silver electrode was first oxidized to silver oxide (AggO). However, a further oxidation to silver peroxide (AggQj) cannot take place, as the electrochemical potential of NlpOj lies between the potentials of AggO and <Ag>gOg, and the additional electrode d after complete charging already develops oxygen at a potential below that of AggOg. As the charging current exclusively leads to the evolution of oxygen at the additional electrode d, the formation of silver peroxide is also reliably avoided in case of longer overcharging. This is appropriate when the accumulator is to be used in a situation that requires a constant voltage during the entire discharge period.
Hvis det kreves en så stor kapasitet som mulig og et ujevnt spenningsforløp ved utladningen ikke virker forstyrrende, så kan det elektrokjemiske potensialet til tilleggselektroden d i oksydert tilstand også være likt eller høyere enn potensialet til sølvperoksyd. Derved kan den positive sølvelektrode a bli oksydert til sølvperoksyd. Da tilleggselektrodens d elektrokjemiske potensial er like stort eller større enn sølvelektrodens a potensial, kan det, da det ikke fore-ligger noe spenningsfall mellom den positive og den negative elektrode, heller ikke vandre oppløste sølvpartikler i retning mot den negative elektrode. If as large a capacity as possible is required and an uneven voltage progression during the discharge does not interfere, then the electrochemical potential of the additional electrode d in the oxidized state can also be equal to or higher than the potential of silver peroxide. Thereby, the positive silver electrode a can be oxidized to silver peroxide. Since the electrochemical potential of the additional electrode d is equal to or greater than the potential of the silver electrode a, since there is no voltage drop between the positive and negative electrodes, dissolved silver particles cannot migrate in the direction of the negative electrode either.
En anordning som vist på fig. 2 har også vist seg hensiktsmessig. Her står tilleggselektroden d i ioneledende kontakt med den positive elektrode a gjennom en videre separator e. Denne utførelses-form kan med fordel benyttes, når tilleggselektrodens d kapasitet har en forstyrrende innvirkning, da i denne anordning tilleggselektroden d ikke tar del i den elektrokjemiske reaksjon. A device as shown in fig. 2 has also proven appropriate. Here, the additional electrode d is in ion-conducting contact with the positive electrode a through a further separator e. This embodiment can be advantageously used when the capacity of the additional electrode d has a disruptive effect, as in this device the additional electrode d does not take part in the electrochemical reaction.
På fig. 3 er skjematisk fremstilt oppbygningen av en akkumulator med flere etter hverandre stående elektroder. Her er de positive elektrodene a fullstendig omgitt av tilleggselektrodene d. Dertne ut-førelsesform vil fortirinsvis komme til anvendelse ved akkumulatorer som er fullstendig fylt med elektrolytt. -Da tilleggselektroden d kan bli utført relativt tynn, og med en materialtykkelse på langt under 1 mm gir en fremragende syklus-bestandighet for en således oppbygget akkumulator, er det fordelaktig ved forminskning av kontaktflaten mellom sølvelektroden og tilleggselektroden å sørge for, at kolloidoppløsté sølvpartikler ikke på grunn av en tilstedeværende overskytende elektrolyttvæske får anledning til å komme utenom tilleggselektroden d. In fig. 3 shows schematically the structure of an accumulator with several consecutive electrodes. Here, the positive electrodes a are completely surrounded by the additional electrodes d. This embodiment will preferably be used for accumulators that are completely filled with electrolyte. - As the additional electrode d can be made relatively thin, and with a material thickness of well below 1 mm provides excellent cycle resistance for an accumulator constructed in this way, it is advantageous by reducing the contact surface between the silver electrode and the additional electrode to ensure that colloidally dissolved silver particles do not due to a present excess electrolyte fluid is allowed to bypass the additional electrode d.
En akkumulator som er bygget opp etter den foreliggende be-skrivelse, med en positiv sølvelektrode bg en negativ elektrode av kadmium, har ved siden av de kjente fordeler ved bruken av en sølv-elektrode, også en levetid som kan sammenliknes med den til nikkel-kadmiumakkumulatorene som finnes i handelen. An accumulator constructed according to the present description, with a positive silver electrode and a negative electrode of cadmium, has, in addition to the known advantages of using a silver electrode, also a lifetime that can be compared to that of nickel the commercially available cadmium accumulators.
