电池体系中氮与锂的反应

Interaction of nitrogen with lithium in battery

研究了N2和锂在电化学体系中的反应,研究表明,在室温下N2和锂在充放电的电化学体系中很容易进行反应,形成的Li3N通过X射线光电子能谱(XPS)进行了表征。实验表明,电流密度越大,温度越高,固氮反应进行得越快;在室温下,氮与锂的反应进行得很完全。

The reaction of N2 and lithium carbide in a battery system was reported in this paper. The reaction of N2 with lithium in this system can take place very easily at room temperature. The prepared Li3N was characterized by XPS. The results also show that the higher of the current density the higher of the temperature goes, and the quicker of the nitrogen-fixation reaction takes place, and that the reaction can be brought about almost completely in an electrochemical system at room temperature.
