The present invention relates to air electrode batteries, that is batteries in which air is admitted to an electrode, normally the cathode, either for normal discharge operation of the battery or, at low or nil discharge rates, to restore or recharge the electrode. A battery is provided having an air electrode wherein at least one air access passageway (5) is closed by a non-liquid valve (9) actuable by differential pressure to provide at least one opening therein to admit air to the battery. |
