Regularly Arranged Micropore Architecture Enables Efficient Lithium-Ion Transport in SiOx/Artificial Graphite Composite Electrode

Caption

  • The internal pores of the electrode were engineered into a regularly arranged micropore (RAM) structure by introducing a perforated and surface-modified Cu current collector (pCu).
  • The pore network, favorable for fast ion transport, effectively mitigates concentration polarization and enables uniform ion distribution, contributing to high-rate operation of lithium-ion batteries.
  • The RAM structure, featuring a unique interlocking electrode configuration and hydroxyl-rich pCu surface, suppressed mechanical degradation and improved long-term cyclability by 50%.
