LIQUID METAL CATHODE MATERIAL AND ROOM-TEMPERATURE LIQUID METAL BATTERY, AND PREPARATION METHOD THEREOF AND USAGE THEREOF

摘要

Disclosed are a liquid metal cathode material and a room-temperature liquid metal battery, and a preparation method therefor and usage thereof. The cathode material is dark green liquid generated by mixing alkali metal, an aromatic compound and an ether solvent. The alkali metal is any one of metallic sodium, metallic lithium or metallic potassium. The aromatic compound is any one of biphenyl, derivatives of biphenyl, naphthaline, derivatives of naphthaline, anthracene or derivatives of the anthracene. The ether solvent comprises one or more of glycol dimethyl ether, diethylene glycol dimethyl ether or tetraethylene glycol dimethyl ether, etc.
