A New Type of Reaction of N₂ with Li

Abstract:

The reaction of N₂ with lithium at electrode in lithium ion batteries was reported in this paper. At room temperature, N₂ can react with lithium, mainly at anode, to form Li₃N in an electrochemical system very easily during charge-discharge cycles. Li₃N has been characterized by XPS. Experimental results also revealed that the higher of the current density and higher of the temperature resulted in quicker of the nitrogen-fixation reaction. The reaction can be brought about almost completely in the lithium ion batteries at room temperature. This could be a new method for preparation of Li₃N at room temperature.
