Germanium (Ge)-air battery, a new type of semiconductor-air battery, has garnered increasing attention owing to its environmental friendliness, safety, and excellent dynamic performance. However, the flat Ge anode is prone to passivation, owing to GeO₂ accumulation on its surface, resulting in premature discharge termination. In this study, various nano-Ge pyramid structures (GePS) were prepared using chemical etching (CE) and metal-assisted chemical etching (MACE) methods to enhance the specific surface area of the Ge anode, thereby facilitating the dissolution of the passivation layer. This study revealed that the MACE method significantly accelerated the etching rate of the Ge surface, producing exceptional GePS. Furthermore, Ge-air batteries employing Ge anodes prepared using MACE demonstrated an exceptional discharge life of up to 9240 h (385 days). The peak power density reached 3.03 mW/cm², representing improvements of more than 2 times and 1.8 times, respectively, compared with batteries using flat Ge anodes. This study presents a straightforward approach to enhance Ge anode performance, thereby expanding the potential applications of Ge-air batteries
