Tailoring nanostructures in micrometer size germanium particles to improve their performance as an anode for lithium ion batteries
A facile and scalable single-step approach is employed to synthesize a bulk germanium electrode, which consists of nanoscale Ge-grains in ∼5 μm porous powders. This three-dimensional Ge electrode exhibits superior specific capacity (∼1500 mA h g −1) and cyclic performance, attributed to its unique lithiation/delithiation processes.
A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs (silicon, germanium and transition metal oxides ), variations of the lithium-ion battery have been announced, although none are commercially available.
