Abstract

The accumulator comprises a container or vessel 2 with a plurality of apertures 4 which form vent passages for the gases evolved in the accumulator. A porous filter element 20 which allows the gases to pass through it but prevents the passage of the electrolyte is provided in each of these passages. This filter element consists of a thin sheet or disc of sintered polytetrafluoroethylene or an element made from glass fibre (or similar non-hygroscopic material) impregnated with polytetrafluoroethylene.
