Nanodispersed molybdenum sulfide decorated with platinum nanoparticles is proposed as a new catalytic nanosystem for a Li–O2 battery. Using platinum as a catalytically active material reduces the overvoltage during charging. Due to the chemical stability of molybdenum sulfide as a support material, the current and power parameters of the system increase to 1000 mA/g, while the number of cycles during uninterrupted operation of the cell reaches 130 (for 500 mA/g). The catalytic system proposed in this study features bifunctional properties and high stability during cycling.
