Problems solved by technology

[0014] However, if the discharge and charging process of the metal-air battery (100) is repeated twice as described above, the moisture in the cathode colloid (122) contained in the cathode (120) decreases, and the cathode colloid (122), that is, the electrolyte and metal zinc The mixture is hardened, there is a problem that the metal-air battery (100) can no longer be used 2 times
[0015] In addition, there is a problem that the number of discharges and charges until the cathode colloid (122) is hardened is less than that of conventional rechargeable batteries such as nickel-hydrogen rechargeable batteries and lithium-ion rechargeable batteries, that is, there are secondary metal air The problem that the life of the battery (100) is shorter than the original rechargeable battery

Abstract

The present invention relates to a metal-air cell charging apparatus, to a metal-air cell assembly, and to a metal-air cell charging system comprising same. The present invention provides a metal-air cell charging apparatus for charging a metal-air cell assembly including a secondary metal-air cell having a negative electrode gel, and a case for accommodating the secondary metal-air cell therein, wherein the metal-air cell charging apparatus comprises: a charging unit which generates, using an external power source, power to be supplied to the metal-air cell assembly, and supplies the thus-generated power to the metal-air cell assembly; and a humidifying air supply unit which generates humidifying air containing a predetermined amount of moisture, and supplies the humidifying air to the interior of the case via a humidifying air supply port connected to the metal-air cell assembly.

Description

technical field [0001] The invention relates to a metal-air battery charging device, a metal-air battery assembly and a metal-air battery charging system comprising the same. In more detail, it relates to a metal-air battery charging device for charging a secondary metal-air battery after the secondary metal-air battery is discharged as a rechargeable metal-air battery, and a charging device including the above-mentioned metal-air battery charging device. The metal-air battery assembly of the secondary metal-air battery and the metal-air battery charging system containing it. Background technique [0002] Electrochemical power sources are devices capable of generating electrical energy by means of electrochemical reactions. Such devices include metal-air batteries such as zinc-air batteries and aluminum-air batteries. A metal-air battery uses a cathode made of metal that is converted into a metal oxide during discharge, an anode that is a permeable membrane containing wate...
