Edge-Affinity-Directed Selective Pore-Mouth Sealing in Coal-Derived Hard Carbon for Stable and High-Capacity Sodium Storage

Abstract Sodium-ion batteries are attractive for large-scale energy storage, but the limited capacity of hard-carbon anodes constrains practical energy density. Increasing porosity can boost capacity, but typically enlarges the electrolyte-accessible surface, lowers the initial C...

Multidirectional Colossal Polarization in a Centrosymmetric Crystal via Long-Range Ion Displacement

Abstract Ferroelectrics exhibit spontaneous polarization and are highly functional materials that are widely used in various devices. However, the design of conventional ferroelectric compounds is largely limited to noncentrosymmetric, polar structures. Herein, we demonstrate tha...
