Abstract
A brand new polysulfide entrapping strategy based on the ferroelectric effect has been demonstrated for the first time. By simply adding the nano-ferroelectrics (BaTiO<sub>3</sub> nanoparticles) into the cathode, the heteropolar polysulfides can be anchored within the cathode due to the internal electric field originated from the spontaneous polarization BaTiO<sub>3</sub> nanoparticles, and thus significantly improving the cycle stability of Li-S batteries.
