Summary: This paper introduces a new inorganic poly(phosphazene disulfide) material. With unique element composition and molecular structure, the polymer has noncombustible safety and preferable conductivity. When used as cathode material for rechargeable lithium batteries, the polymer's first discharge capacity is as high as 467.9 mAh · g −1 , which can be retained at 409.9 mAh · g −1 after 60 repeated cycles. Therefore, it has a great application potential in the field of lithium batteries.Replacement of the Cl atoms by SS groups by refluxing Na 2 S 2 and linear poly(dichloro‐phosphazene).
