SECONDARY ELEMENT USING SULFUR-ORGANIC/METAL MATERIALS OF CHARGE TRANSFER AS POSITIVE ELECTRODE Russian patent published in 1999 - IPC

FIELD: secondary sources of electric energy. SUBSTANCE: invention refers to secondary sources of electric energy containing metal and sulfur-organic material on positive electrode. It has internal coupling of metal to sulfur and changes state of oxidation of metal during charging and discharging of positive electrode. Positive electrode has composition of general formula , where z is equal to 1 or 2, y has magnitude from 1 to 20, x has magnitude from 1 to 10, c has magnitude not more than 10, n is larger or equal to 1, q has magnitude from 1 to 10, M' is metal or another cation, M is any multivalent metal in various repeating units of polymer metal and sulfur-organic material, R is organic group having 1 to 20 carbon atoms and including one or several organic radicals chosen from group composed of aliphatic chains, aromatic rings, alycyclic rings and combinations of aliphatic chains, aromatic and alycyclic rings given that R does not have explosive aromatic rings. EFFECT: increased specific electric characteristics and enlarged working interval of temperatures of sources of electric energy. 11 cl, 4 dwg, 2 tbl
