Description

technical field

[0001] The invention relates to a lithium-air battery. Background technique

[0002] In recent years, lithium-air batteries, which have been developed as power sources for portable electronic devices and electric vehicles, have significantly higher energy density than lithium-ion batteries by bringing lithium into contact with air, and have the advantages of miniaturization and light weight. Quantified and other advantages of the battery.

[0003] Such a lithium-air battery is used by injecting an electrolyte into a secondary battery cell comprising: a positive electrode containing a positive electrode active material that oxidizes and reduces lithium; a negative electrode containing a negative electrode active material that can intercalate and extract lithium substance.

[0004] Generally, lithium metal is mainly used as the above-mentioned negative electrode active material, but if lithium metal comes into contact with water, a sharp explosive reaction wi...
