Abstract

Blyakkumulator, hvor den negative elektroden er forsynt med nødvendig ekspander i vesentlig en lignin-holdig depotsubstans, fortrinnsvis tremel, som imidlertid er blandlngsbestanddel til den aktive massen for den positive elektroden. Depotsubstansen ved den positive elektroden utsettes i løpet av formasjonen av sykli-serlngen for en oksidativ nedbrytning ved hvilken oppløselig ligninderivat frisettes. En slik ekspander-kllde tillater fremstilling av den negative massen uten ekspandertillegg og det unngås en overdosering, som ellers er tilstede ved begynnelsen av idriftsettingen av et batteri. Via konsentrasjon av partikkelstørrelsen på tremelet er det mulig å stort sett moderere styrken på ekspandertilførselen til den negative elektroden og dens varighet.Lead accumulator, in which the negative electrode is provided with the necessary expander in substantially a lignin-containing depot substance, preferably wood flour, which, however, is a mixture component of the active mass of the positive electrode. The depot substance at the positive electrode is subjected during the formation of the cyclization to an oxidative degradation at which soluble lignin derivative is released. Such an expander source allows the production of the negative mass without expander addition and an overdose, which is otherwise present at the beginning of the commissioning of a battery, is avoided. Via concentration of the particle size of the wood flour, it is possible to largely moderate the strength of the expander supply to the negative electrode and its duration.
