Abstract: 

Poly(5-vinyl-2-methylpyridine) sulfurized with elemental sulfur at 140-320°C (sulfur content up to 45%) possess electric conductivity (6.4·10-11-1.6·10-7 S/cm), paramagnetism 6.2·1018–5.0·1019 sp/g, g = 2.0043-2.0046, AH = 0.49-0.58 mT), redox and complex-forming properties. A preliminary estimation of its electrochemical properties indicates that the polymer can be used as an active cathode material in model lithium accumulators of button cell type and allows repeated cycling of the latter at a specific charge capacity of 250-330 mA·h/g.
