Tailoring nanostructures in micrometer size germanium particles to improve their performance as an anode for lithium ion batteries

摘要

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.
