摘要
Herein, a stacked Ge/Cu nanowire (NW) laminate made by stacking several Ge/Cu nanowire laminates accompanied by the conductive glue adhesives is used to achieve high capacity output per unit area (>10 mA h cm <sup>-2</sup> ). The combination of Cu NWs and conductive adhesives constructs a tough and conducting network through the electrode, and the stacked Ge/Cu nanowire laminate electrodes can load an ultrahigh mass of 14.8 mg Ge per unit area and provide an areal capacity output over 16 mA h cm <sup>-2</sup> . A full-cell with an areal capacity of 11 mA h cm <sup>-2</sup> built by stacked Ge/Cu nanowire laminate anode and Li(Ni <sub>0.5</sub> Co <sub>0.3</sub> Mn <sub>0.2</sub> )O <sub>2</sub> cathode was prepared and used to supply electricity for electronic devices, demonstrating their potential to be a candidate anode for high areal capacity Li-ion microbatteries that can be used for high-tech and integrated microsystems with limited space.
