ACTIVE CATHODE MATERIALS FOR LITHIUM CURRENT SOURCES CONTAINING COMPOSITIONS CONSISTING OF COLLOIDAL CROSS-LINKED COPOLYMERS BASED ON SULPHUR AND ANILINE

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to colloidal cross-linked copolymers based on sulphur and aniline, containing conducting and non-conducting polymer links, meant for use as active cathode materials for chemical current sources. Disclosed is a cathode composition containing active cathode material in form of a colloidal cross-linked copolymer of sulphur and aniline, as well as acetylene black and polyethylene oxide. Also disclosed is a method of producing colloidal cross-linked copolymers of sulphur and aniline via oxidative copolymerisation in the presence of oxidative systems (H2O2/FeCl3/HCl or H2O2/FeSO4/H2SO4). ^ EFFECT: use of said copolymers as active cathode material of lithium batteries ensures stable operation of cells with high charge-discharge capacity and long cycling. ^ 2 cl, 9 ex
