Abstract

On réduit sensiblement le bouillonnement dans les piles électrochimiques comportant des anodes métalliques, par exemple en zinc, en réduisant le nombre des grains dans les particules du métal polycristallin jusqu'à moins un tiers du nombre initial des grains, cette réduction étant provoquée par un traitement thermique du métal d'anode à une température inférieure à son point de fusion, la corrosion étant réduite avec ces particules à nombre réduit de grains et en particulier avec des particules monocristallines par l'addition dans la pile de petites quantités d'un agent tensio-actif inhibiteur de dégagement de gaz, par exemple un phosphate organique.The boiling is substantially reduced in electrochemical cells comprising metal anodes, for example zinc, by reducing the number of grains in the particles of polycrystalline metal to at least one third of the initial number of grains, this reduction being caused by a treatment thermal of the anode metal at a temperature below its melting point, corrosion being reduced with these particles with reduced number of grains and in particular with monocrystalline particles by the addition in the pile of small quantities of a surfactant -active gas release inhibitor, for example an organic phosphate.
