- - Transition metal oxide-sulfur composite materials for cathodes in lithium-sulfur batteries and preparation method thereof

摘要

The present invention relates to a transition metal oxide-sulfur composite cathode active material for a lithium-sulfur secondary battery and a method of manufacturing the same, and includes sulfur nanoparticles and α-transition metal oxide nanowires coated on all or a part of the surface of the sulfur nanoparticles Thus, after the first charge / discharge cycle, lithium is inserted into the? -Transition metal oxide nanowire, thereby inhibiting the elution of lithium polysulfide and enhancing the conductivity of sulfur and improving the rate characteristics of the battery.
