Local Electric‐Field Homogenization via Ferroelectric Grain‐Boundary Engineering Enables Long‐Life, High‐Rate Solid‐State Sodium Metal Batteries

ABSTRACT Achieving dendrite‐free and stable interfaces remains a critical challenge for solid‐state sodium metal batteries (SSMBs), especially under low‐temperature and high‐rate conditions. Here, we report a scalable grain boundary engineering strategy by integrating ferroelectr...
