主　　题：Electrochemical intercalation reaction of lithium into sulfides of nonlayer structure 

摘      要：The reaction mechanism of cell Li/PbS has been studied with coulombic titration,cyclicvoltammetry and X-ray diffraction *** was found that in the first stage of discharge（0y≤1.5）,the intercalation of lithium into lead sulfide took *** X-ray diffraction patterns showedthat the main crystalline structure of PbS remained unchanged after lithiation,and the lithium inter-calated probably locates in the center of the cubic-interspace of the *** intercalation freeenergy of Li into PbS forming LiPbS was found to be-300.48 ***-1（at 25℃）.The chemicaldiffusion coefficient of lithium in LiyPbS（0y5≤1）was determined by electrochemical method tobe about 10-11cm2s-1.
