Area of Science:

  • Materials Science
  • Electrochemistry
  • Nanotechnology

Background:

  • Germanium (Ge) is a promising high-capacity anode material for lithium-ion batteries (LIBs).
  • Poor electrical conductivity and capacity decay limit Ge's practical application in LIBs.
  • Nanoporous structures can mitigate volume expansion issues in Ge anodes.

Purpose of the Study:

  • To synthesize Sn-modified nanoporous Ge materials.
  • To investigate the effect of Sn modification on the electrochemical performance of Ge anodes for LIBs.
  • To optimize the Ge/Sn atomic ratio for superior lithium storage.

Main Methods:

  • Melt-spinning and dealloying techniques were employed for material synthesis.
  • Electrochemical testing, including cycling stability and rate capability, was performed.
  • Density functional theory (DFT) calculations were used to understand the mechanisms.

Main Results:

  • Sn-modified nanoporous Ge anodes demonstrated improved cycling stability over Sn-free counterparts.
  • The Ge/Sn atomic ratio of 3:1 yielded the best performance, with a reversible capacity of 974 mAh/g after 500 cycles at 200 mA/g.
  • Sn introduction regulated the nanoporous structure, alleviated volume expansion, and enhanced conductivity and activity.

Conclusions:

  • Sn modification is an effective strategy to enhance the electrochemical properties of Ge-based anodes for LIBs.
  • Optimized Sn content improves structural integrity and electronic conductivity, leading to better cycling performance.
  • This research offers a viable route for developing high-performance LIBs using modified Ge anodes.
