Power supply system for e.g. portable electronic devices, has metal-air battery with cathode in which rich oxygen gas and inert gas or low carbon dioxide gas is temporarily supplied from air separation plant

摘要

The power supply systems (10,20) include a metal-air battery (1) and an air separation plant (2). The cathode of the metal-air battery is temporarily supplied with rich oxygen gas and inert gas or low carbon dioxide gas from the air separation plant. A common gas network (4) is provided with two subnets (4a,4b) for supplying the rich oxygen gas and inert gas. The metal-air battery is designed as lithium-air battery, aluminum-air battery, magnesium-air battery, zinc-air battery or iron-air battery. An independent claim is included for a method for power operating supply system.
