Ferroelectric Engineered Electrode-Composite Polymer Electrolyte Interfaces for All-Solid-State Sodium Metal Battery.

ABSTRACT: To enhance the compatibility between the polymer-based electrolytes and electrodes, and promote the interfacial ion conduction, a novel approach to engineer the interfaces between all-solid-state composite polymer electrolyte and electrodes using thin layers of ferroelectrics is introduced. The well-designed and ferroelectric-engineered composite polymer electrolyte demonstrates an attractive ionic conductivity of 7.9 × 10^-5 S cm^-1 at room temperature. Furthermore, the ferroelectric engineering is able to effectively suppress the growth of solid electrolyte interphase (SEI) at the interface between polymer electrolytes and Na metal electrodes, and it can also enhance the ion diffusion across the electrolyte-ferroelectric-cathode/anode interfaces. Notably, an extraordi
