FUEL ELEMENT FOR MAGNESIUM-AIR BATTERY, MAGNESIUM-AIR BATTERY, PRODUCTION METHOD FOR FUEL ELEMENT FOR MAGNESIUM-AIR BATTERY, MAGNESIUM-AIR BATTERY SYSTEM, AND USE METHOD FOR MAGNESIUM-AIR BATTERY SYSTEM

摘要

A magnesium-air battery system (200) comprises a supplier (210), a battery body (220), a wind-up reel (230) and a driver (240). A magnesium-air battery fuel element (100) is formed from a magnesium film into a roll shape. The supplier (210) is connected to the magnesium-air battery fuel element (100) and is rotationally driven by the driver (240) such that the magnesium-air battery fuel element (100) is delivered to the wind-up reel (230) via the battery body (220). The battery body (220) comprises an anode and an electrolyte and uses the magnesium-air battery fuel element (100) as a cathode acting in synergy with the anode to generate electricity. The wind-up reel (230) winds up the post-reaction magnesium-air battery fuel element that is used to generate electricity in the battery body (220), and forms a used fuel element (500) having a roll shape removable from the wind-up reel (230).
