摘　　要：报道了Ｌｉ－ＳＣｌ２和Ｌｉ－Ｓ２Ｃｌ２非水电池体系的研究工作。该体系由锂负极、多孔石墨电极和电解质溶液构成，电解质溶液由非水溶剂（硝基苯）和溶解在该溶剂中的活性物质ＳＣｌ２或Ｓ２Ｃｌ２及电解质构成。制成锂片和碳膜面积为１ｃｍ２、所含电解液为０．４ｍＬ的模似电池，将其在恒流放电测试系统中进行测试。结果表明：Ｌｉ－ＳＣｌ２电池的开路电压为４．１０Ｖ左右，当ＳＣｌ２与溶剂硝基苯的体积比为１５％至２０％时，电池显示良好的放电性能；而Ｌｉ－Ｓ２Ｃｌ２电池的开路电压为３．６Ｖ左右，当Ｓ２Ｃｌ２与硝基苯的体积比为２５％时，电池体系也显示较好的放电性能。此外，对电池体系的电化学还原行为也作了初步的探索。Researches on Li SCl 2 and Li S 2Cl 2 non aqueous battery systems have been reported. This system consists of a matallic lithium anode (negative electrode),a porous graphite electrode and electrolyte solution containing a mixture of positive active material SCl 2 or S 2Cl 2. Organic solvent (nitrobenzene) and electrolyte. The area of lithium anode or graphite electrode is 1cm 2 and the volume of electrolyte solution is 0.4 mL. This model battery is discharged in constant current. The testing results showed that Li SCl 2 battery has higher open circuit voltage (4.1V) and behaves good discharging performance when the ratio of SCl 2 to nitrobenzene in volume is from 15% to 20%. The Li S 2Cl 2 has open circuit voltage (3.6V) and behaves good performance when volume of S 2Cl 2 to volume of nitrobenzene is 25%. In addition the electro chemical reduction process of the battery systems was also studied.
