摘要
The present invention relates to a positive electrode active material for a lithium-sulfur battery containing polyimide, more specifically, a positive electrode active material formed by complexing the composite of polyimide and carbon-based secondary particles with sulfur particles, a preparation method thereof and a lithium-sulfur battery comprising the same. If the positive electrode active material formed by including and complexing the polyimide according to the present invention is applied to the lithium-sulfur battery, the elution of the polysulfide is suppressed, and thus lifetime characteristics and energy efficiency are improved.
