AIR-METAL SECONDARY BATTERY UNIT AND AIR-METAL SECONDARY BATTERY MODULE INCLUDING SAME

摘要

The present invention relates to an air-metal secondary battery unit and an air-metal secondary battery module including the same. The present invention provides an air-metal secondary battery module, comprising: one or more metal-air secondary battery units, each of which has a water intake part for taking an aqueous solution therein and a gas outlet port for discharging gas generated during charging; an aqueous solution storage unit which stores the aqueous solution; an aqueous solution supply unit which connects the one or more water intake parts to the aqueous solution storage unit; and a gas discharge unit which is connected to the one or more gas outlet ports to discharge the gas discharged from the gas outlet ports to the outside. According to the present invention, it is possible to prevent hardening of a negative electrode gel due to the discharging and charging of one or more metal-air secondary battery units and to prevent the expansion of a battery case due to gas generation, so that the metal-air secondary battery can be modularized to be commercially used in various fields, for example, in a vehicle battery, in which high-capacity electric energy is required.
