Sulfur composites and polymeric materials having a high sulfur content and prepared from elemental sulfur as the primary chemical feedstock. The sulfur copolymers are prepared by the polymerization of elemental sulfur with one or more monomers of amines, thiols, sulfides, alkynylly unsaturated monomers, nitrones, aldehydes, ketones, thiiranes, ethylenically unsaturated monomers, or epoxides. The sulfur copolymers may be further dispersed with metal or ceramic composites or copolymerized with elemental carbon, photoactive organic chromophores, or reactive and solubilising/biocompatible moieties. The sulfur composites and polymeric materials feature the ability self-healing through thermal reformation. Applications utilizing the sulfur composites and polymeric materials may include electrochemical cells, optics, H.sub.2S donors and antimicrobial materials.

In order to improve the safety of a rechargeable battery, methods for manufacturing the rechargeable battery using a solid-state electrolyte are being studied. However, a process of manufacturing the all-solid state rechargeable battery by separately preparing and laminating an electrode and a solid-state electrolyte is not only complicated, but also may cause side reactions due to residual moisture between the electrode and the solid-state electrolyte. In addition, additional processes are required to reduce the interface resistance between the electrode and the solid-state electrolyte. In order to solve these disadvantages, the present invention is to manufacture an integral all-solid state rechargeable battery by applying a mixed slurry of a conductive ceramic material and a polymer mixed with a solvent onto an electrode, evaporating the solvent, absorbing a liquid electrolyte, and then covering the electrode with a counter electrode. The manufacturing method of the integral all-solid state rechargeable battery has an effect of simplifying the manufacturing steps, suppressing side reactions, and reducing the interface resistance between the electrode and the solid-state electrolyte.
