title: Ferroelectric-Enhanced Polysulfide Trapping for Lithium-Sulfur Battery Improvement.
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 (BaTiO3nanoparticles) into the cathode, the heteropolar polysulfides can be anchored within the cathode due to the internal electric field originated from the spontaneous polarization BaTiO3nanoparticles, and thus significantly improving the cycle stability of Li-S batteries.
