锂合金的电解制备及性能研究Ⅱ.：锂铝合金的循环效率和稳定性

室温下LiAl合金是在LiClO_4有机溶液中于不同的Al基质上制备的。本工作研究了Li在LiAl合金上的循环效率,发现在Al_2基质上形成的LiAl合金的循环效率高达98.7％,研究了在各种条件下LiAl合金的稳定性。在干燥空气下,合金不仅能长时间保存,而且在25％湿度下放置22小时,损失仅接近于50％。因此,在适当厚度的铝基质上形成的LiAl合金能够在室温二次锂电池中使用。

Electrolysis Preparation and Preformance Study of Lithium Alloy The Cycling Efficiencies and Stability of LiAl Alloy

LiAl alloy on several kinds of substrates was prepared in some organic solution of LiClO_4 at room temperature. The cycling efficiencies of Lithium in the LiAl alloy was examined and it was found the LiAl alloy of formation on Al_2 subatrate showed a high cycling efficiency up to 98, 7%. In the prerent work, the stability of LiAl alloy was also examined on various conditions. In the dry air the LiAl alloy could be well preserved for a long time. and it only lost approximately 50％ at 25% air humidity when it was held for 22hrs. Thus the LiAl alloy formed on the fit thin Aluminium subatrate could be used as an anode of sesondary Lithium cells at room temperature.
