The amorphous GeO_x (x < 1) was synthesized and investigated its suitability as a Na-ion battery anode. GeO_x was synthesized by oxidizing Zintl-phase NaGe with isopropyl alcohol at room temperature. The amorphous GeO_x showed good electrochemical Na storage as an anode for Na-ion batteries, with first reversible capacity of 342 mAh g⁻¹, high power of 237 mAh g⁻¹ (6 A g⁻¹), and cycle performance, retaining a capacity of 216 mAh g⁻¹ after 40 cycles.
