Beschreibung
Zusammenfassung:	A hermetically sealed lead-acid storage battery which evolves gas during charging, comprises a hermetically sealed container, a lead dioxide cathode located in the container, a lead anode located in the container, a gas absorbing electrode located in the container, the gas absorbing electrode consisting essentially of 20-80% by weight of an electrically conductive carbonaceous material and 80-20% by weight of a slightly water soluble quinoid compound having a low oxidation--reduction potential, and a liquid acid electrolyte located in the container and partially filling same so as to define a gas space in the container. The cathode, anode and gas absorbing electrode are in contact with the electrolyte and with the gas space. Upon charging of the battery, gas formed in the container is absorbed by the gas absorbing electrode. The storage battery of the invention can be used in aviation and space engineering, on motor and water transport, in radioelectronic and medical equipments. It is operable at temperatures which may reach -50.degree.C.
