Abstract: A binder for a lithium-sulfur electrode is proposed. The binder can improve the capacity and lifespan characteristics of a lithium-sulfur secondary battery by suppressing the shuttle reaction due to the elution of polysulfide through the interaction of lithium polysulfide while maintaining the binding characteristics of the binder. This binder may be used for a positive electrode and a lithium-sulfur secondary battery. The binder may include a modified polyvinylidene fluoride (PVdF)-based binder that is soluble in an organic solvent. The modified PVdF-based binder may include a PVdF-based main chain and a functional group having a carboxylic group or carbonyl group grafted as a side chain.
