• • The original article reported Na0.44MnO2 with intrinsic pseudocapacitive behavior, achieving high rate capability and robust cycling stability for sodium-ion batteries, but this correction does not alter the reported electrochemical data.
• • The correction ensures proper attribution of the first author's multiple affiliations, which is critical for institutional credit and research accountability.
• • The corrected affiliations include three institutions: Shanghai Institute of Ceramics (CAS), Peking University, and University of Chinese Academy of Sciences, reflecting the collaborative nature of the research.
• • This correction maintains the integrity of the scientific record, as the original findings on Na0.44MnO2 remain unchanged, but the metadata is now accurate for citation and evaluation purposes.
