Tunnel-type NaGeMnO was fabricated for anode of sodium ion batteries, delivering a discharge capacity of 200.32 mAh g and an ultra-low potential platform compared with that of pure NaGeO (NGO). 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.
隧道型NaGeMnO被制备用于钠离子电池的阳极，与纯NaGeO（NGO）相比，其放电容量为200.32 mAh g ，且具有超低电位平台。X射线光电子能谱（XPS）结果表明发生了Ge氧化还原反应，与NGO相比，Mn的部分取代有效地改善了储钠性能。
