锂电池Li／KIBr_2—非水体系的研究

RESEARCH ON lI/KIBR_2-NON-AQUEOUS BATTERY SYSTEM

本非水电池体系由Ｌｉ负极、多孔石墨电极和电解质溶液组成；电解质溶液由无机溶剂ＰＯＣｌ＿３（或有机溶剂硝基苯）和溶解在该溶剂中的活性物质（ＫＩＢｒ＿２）及支持电解质构成。该电池体系的开路电压为８．５０伏左右，放电性能良好，可望在实际中得到应用。此外，对电池体系的反应机理也作了初步的探讨。

he The battery system is made up of Li metal anode ,a porous graphite cathode-current collectorand an electrolyte solution containing a cathode active material (KIBr_2),non-aqueous solvent(POCl_3 or nitrobenzene)and supporting electrolyle.The descharge of the battery systems have been examined,The battery systems have open voltage (about3.5v)with good performance.Explorato-ry research on the electrochemical reduction process for the system is also presented.
