Abstract
A subzero‐temperature cathode material is obtained by nucleating cubic prussian blue crystals at inhomogeneities in carbon nanotubes. Due to fast ionic/electronic transport kinetics even at −25 °C, the cathode shows an outstanding low‐temperature performance in terms of specific energy, high‐rate capability, and cycle life, providing a practical sodium‐ion battery powering an electric vehicle in frigid regions.Keywords
