Abstract
The invention relates to a method for the manufacture of an electrochemical cell or battery, consisting of a stack of plate-shaped elements, each of which consists of a sheet or plate of electrode material which is mounted in a frame made of electrically insulating fibrous-web material impregnated with a non-polymerized thermosetting synthetic material, which elements in a first compression molding stage are heated under pressure for a relatively short primary time at a relatively low primary temperature under which conditions the thermosetting synthetic material flows well but polymerizes only to a minor degree, thereafter the elements are combined with other battery components are stacked into an electrochemical cell package which in a second compression molding stage is formed into a coherent block by compression for a relatively long secondary time and at a relatively high secondary temperature to set the thermosetting synthetic material.
