HYBRID THREE-DIMENSIONAL SULFUR CO-POLYMERS COMPRISING CONDUCTING AND NON-CONDUCTING POLYMERIC BLOCKS AND THEIR COMPOSITIONS WITH SULFUR USED AS CATHODE MATERIALS

摘要

FIELD: chemistry of polymers.;SUBSTANCE: invention relates to a cathode composition for lithium accumulators. The composition comprises hybrid three-dimensional co-polymer of sulfur comprising polyaniline three-dimensional chain bound with part of polymeric sulfur comprising oxidized atoms of sulfur and elemental sulfur. Invention provides the more number of cycles discharge-charge as compared with the known materials and to enhance the reducing capacity of secondary cell with capacity values above 900 A x h/kg.;EFFECT: improved and valuable properties of co-polymers.;4 cl, 6 ex
