NOVELTY - A positive electrode composition comprises (a) sulfur complex (I), and (b) at least one additive. USE - Positive electrode composition used for all-solid-state battery (claimed) for hybrid vehicles and electric vehicles. ADVANTAGE - The composition improves conductivity and specific capacity of the solid-state batteries. DETAILED DESCRIPTION - A positive electrode composition comprises (a) sulfur complex of formula: S-C-PXn (I), and (b) at least one additive. S = elemental sulfur; C = conductive carbon; PX = phosphorus halide; X = Cl, Br or I;and n = 3-5. INDEPENDENT CLAIMS are included for the following: (1) preparation of positive electrode composition; and (2) all-solid-state battery.
