The results of X-ray photoelectron spectroscopy (XPS) demonstrate that Ge redox occurs, and partial substitution of Mn effectively improves the Na-storage properties compared to those of NGO.RSC advances1426-1429https://www.ebi.ac.uk/biostudies/studies/S-EPMC9048186biostudies-literatureA stable tunnel-type NaGe<sub>3/2</sub>Mn<sub>1/2</sub>O<sub>4</sub> anode for Na-ion batteries.PMC9048186Liu XCui YLei XZhang RfalseA stable tunnel-type NaGe<sub>3/2</sub>Mn<sub>1/2</sub>O<sub>4</sub> anode for Na-ion batteries.Tunnel-type NaGe<sub>3/2</sub>Mn<sub>1/2</sub>O<sub>4</sub> was fabricated for anode of sodium ion batteries, delivering a discharge capacity of 200.32 mAh g<sup>-1</sup> and an ultra-low potential platform compared with that of pure Na<sub>4</sub>Ge<sub>9</sub>O<sub>20</sub> (NGO).
