In a gas-recombination lead accumulator, the electrolyte includes additives selected from the group consisting of ions of tin, selenium and bismuth and/or organic molecules selected from the group consisting of n-dodecylamine, 2,3,4-trimethoxybenzaldehyde, 3,5-diaminobenzoic acid, nicotinic acid and their sodium, potassium and magnesium salts. The presence of the aforesaid additives has the effect of inhibiting the discharge of hydrogen and/or promoting the reduction of oxygen at the negative electrode.

Lead accumulator with gas recombination

An electrical accumulator has an electrically-insulating container with a covering which reflects infra-red radiation.

Electrical accumulators and batteries of accumulators provided with

The method enables the manufacture of dry-charged batteries, the plates whereof are constituted by pasted grids, intercalated with separators and assembled in an insulating container closed by a lid provided with gas vents. The pasted grids and the separators are assembled in the container before the forming process, and the plates are subjected to the forming process and to subsequent washing in the container itself. The completed battery, fitted with its lid, is then dried by microwave heating in an environment containing a hot inert gas.
