英文摘要	Novel inorganic network polymer phosphazene disulfide [(NPS2)(3)](n) was synthesized by a solution cross-link method. IR and element content analysis confirmed the polymer's molecular structure. The polymer has an average particle size of d(0.5)=7.7 mu m and the specific surface area is 57.4 m(2) g(-1). TG/DTA analysis showed that [(NPS2)(3)](n) underwent a decomposition reaction from 200 to 300 degrees C. When used as cathode material in lithium batteries, its initial discharge capacity was 459.1 mAh g(-1), which is almost 93.5% of theoretical specific capacity (490.9 mAh g(-1)). After 30 charge-discharge cycles, the discharge capacity of [(NPS2)(3)](n) stabilized at approximately 400.1 mAh g(-1) which revealed an excellent cyclic ability. Therefore [(NPS2)(3)](n) is of great potential as cathode material for secondary lithium batteries. (c) 2005 Elsevier B.V.
