Abstract

We report a facile two-step method to synthesize nanostructured P2-Na_2/3MnO₂via ligand exchange and intercalation of sodium ions into ultrathin manganese oxide nanoplates. Sodium storage performance of the synthesized material shows a high capacity (170 mA h g⁻¹) and an excellent rate performance.
