Abstract

The built-in electric field induced by BaTiO3 homogenizes the interfacial charge distribution, which can facilitate the Na+ ion diffusion and effectively suppress sodium dendrite formation at the source. Such a ferroelectric carboxylated cellulose/BaTiO3 separator enables long-term cycling stability of sodium metal batteries.
