Abstract
Inventia se refera la un procedeu de realizare a electrozilor catodici pentru pile si baterii alcaline apartinînd sistemului electrochimic HgO/KOH/Zn. Potrivit procedeului, într-o prima etapa se procedeaza la omogenizarea unui amestec de pulberi cu granulatie sub 75 în proportii procentuale gravimetrice de 90% HgO, 7,4% electrografit, 2,6% polietilena, proportii care pot varia în limite restrînse în functie de morfologia particulelor care alcatuiesc pulberile. Acestea sînt presate cu o forta de presare de 0,4...0,6 tf/cm indice 2 într-o matrita avînd configuratia dorita, realizîndu-se astfel elementul catodic presat. în continuare, se confectioneaza colectorul de curent cu aceeasi configuratie prin ambutisare marginala sau sudare în punct cu curenti de impuls a elementelor componente ale desfasuratei sale geometrice. Materialul folosit este tabla de nichel sau de otel nichelat cu grosimea de 0,08...0,14 mm pe care s-au practicat prealabil perforatii de 0,05...0,15 mm exponent 2 la distante de circa 1...2 mm. în colector este introdus elementul catodic presat din materialul depolarizat.The invention relates to a process for the manufacture of cathode electrodes for cells and alkaline batteries belonging to the electrochemical system HgO / KOH / Zn. According to the process, in a first step, a mixture of powders with a grain size below 75 is carried out in gravimetric proportions of 90% HgO, 7.4% electrographite, 2.6% polyethylene, proportions which may vary within the limits of the function the morphology of the particles that make up the powders. These are pressed with a compressive force of 0.4 ... 0.6 tf / cm of index 2 in a mold having the desired configuration, thus making the pressed cathode element. Next, the current collector is made with the same configuration by marginal stamping or welding at the impulse current point of the components of its geometric unfolding. The material used is nickel or nickel-plated steel with a thickness of 0.08 ... 0.14 mm on which perforations of 0.05 ... 0.15 mm of exponent 2 have been applied at distances of about 1. .2 mm. the cathode element pressed from the depolarized material is introduced into the collector.
