The development and the characterization of a nanostructured binder-free anode for lithium-ion batteries exploiting the germanium high theoretical specific capacity (1624 mAh g⁻¹ for Li₂₂Ge₅ alloy) is herein presented. This anode secures remarkable performances in different working conditions attaining a 95% capacity retention at 1C (i.e., 1624 mA g⁻¹) after 1600 cycles at room temperature and a specific capacity of 1060 mAh g⁻¹ at 10C and 450 mAh g⁻¹ at 60C. The nanostructured binder-free germanium-based anode shows also strong resilience in terms of temperature tests, being it tested from -30 °C to +60 °C. Indeed, the specific capacity remains unaltered from room temperature up to +60 °C, while at 0 °C the cell is still retaining 85% of its room temperature capacity. In a full-cell configuration with LiFePO₄ as cathode, the Ge anode showed a stable specific capacity above 1300 mAh g⁻¹ for 35 …
