Catalysis‑Induced Highly‑Stable Interface on Porous Silicon for High‑Rate Lithium‑Ion Batteries (IMAGE)
Caption
- In situ etching and co-growth of ultra thin defect-rich oxide layers on porous silicon.
- Through the construction of nano-sized catalytic interface, the electrolyte addition FEC would decompose to a LiF-rich solid electrolyte interphase (SEI).
- The robust SEI on porous structured silicon performs high-rate stability at varied temperatures.
