摘要
报道了Ｌｉ－ＩＣｌ非水电池体系的研究工作。本非水电池体系由锂负极、多孔石墨电极和电解质溶液构成，电解质溶液由有机溶剂硝基苯或无机溶剂三氯氧磷（ＰＯＣｌ３）和溶解在该溶剂中的活性物质ＩＣｌ及电解质构成。在制作该类模拟电池过程中，首先对溶剂硝基苯和电解质（ＡｌＣｌ３及ＬｉＡｌＣｌ４）进行干燥纯化，然后在惰性气氛操作箱中装好模拟电池，模拟电池的集流体为镍，锂片和碳膜的面积为１ｃｍ２，电池中所含电解液为０．４ｍＬ。将该模拟电池在恒流放电测试系统中进行测试，结果表明：当电解质采用ＬｉＡｌＣｌ４时，ＩＣｌ的浓度为１ｍｏｌ／Ｌ，该类非水电池具有较高的开路电压（３．９０Ｖ左右），并显示良好的放电性能。此外，对电池体系的电化学还原行为也进行了初步的探索。
Research on Li ICl non aqueous battery systems had been reported. This non aqueous battery system consisted of a metallic anode (negative electrode), a porous graphite electrode and electrolyte solution containing a mixture of positive active material ICl, organic solvent (nitrobenzene) or inorganic solvent (POCl 3) and electrolyte. Firstly, the solvent (nitrobenzene) and electrolyte (LiAlCl 4 or AlCl 3) must be dehydrated. Secondly, the model battery must be manufactured in the box which was full of Ar gas during the manufacturing process of model battery. The collector of battery was metallic (Ni). The area of lithium anode or graphite electrode was 1cm 2 and the volume of electrolyte solution was 0.4mL. This model battery was discharged at constant current. The results of tests show that when LiAlCl 4 is used as electrolyte and the concentration of ICl is 1mol·L -1 , the battery system has higher open circuit voltage (3.90V) and behaves good performance of discharge. In addition, the electrochemical reduction process of the battery system was also studied.
