Multifunctional Conductive and Elastic Matrices‑Engineered Si Nanocomposite Anodes for Liquid and Solid‑State Lithium Batteries

Caption

  • A Si nanocomposite (Si/a-Sn/CoSi2/G/C) anode incorporating multifunctional conductive–elastic matrices was fabricated via a simple and scalable route.
  • The multimatrix design sustains electronic percolation, facilitates Li+ transport, and provides multilevel stress buffering with elastic recovery to mitigate Si chemo-mechanical degradation.
  • Si/a-Sn/CoSi2/G/C-based full-cells achieve high energy densities in both liquid and solid-state systems (434.4 Wh kg–1 in LIBs and >300 Wh kg–1 in all-solid-state lithium batteries) with durable cycling stability.
