Document Type and Number:
WIPO Patent Application WO/2020/138668
Kind Code:
A1
Abstract:
Provided is, according to the present technology, a secondary battery capable of charging and discharging, comprising: a cathode unit including a first electrolyte which is an aqueous electrolyte accommodated in a first reaction space, and a cathode which is at least partially submerged in the first electrolyte; and an anode unit including a second electrolyte which is an aqueous electrolyte accommodated in a second reaction space, and an anode which is at least partially submerged in the second electrolyte, wherein carbon dioxide gas is introduced into the first electrolyte, and hydrogen ions and bicarbonate ions are generated by a reaction between water of the first electrolyte with the carbon dioxide gas , and the hydrogen ions and the electrons of the cathode are combined to generate hydrogen gas.
