Introducing　a　conductive　carbon　layer　between　the　copper　foil　current　collector　and　silicon　active　material　effectively　mitigates　electrode　damage　and　battery　capacity　loss　caused　by　uneven　silicon　expansion.　In　this　study,　a　low-cost,　environmentally　friendly　carbon-coated　copper　foil　(CCF)　is　designed　using　zeolitic　imidazolate　framework　8-derived　carbon　(ZPC)　as　the　carbon　source,　polyethylenepyrrolidone　(PVP)　as　the　binder,　and　deionized　water　as　the　solvent.　The　large　surface　area　and　porosity　of　ZPC　effectively　accommodate　the　volume　expansion　of　silicon,　thereby　enhancing　the　overall　performance　of　the　battery.　The　bare　copper　foil　electrode　experiences　rapid　decay,　with　a　failure　occurring　after　just　75　cycles　at　0.5　C.　In　contrast,　the　CCF　electrode　maintains　a　reversible　capacity　of　576.8　mAh/g　even　after　200　cycles.　The　CCF　electrode　demonstrates　superior　specific　capacity　and　cycle　stability　in　both　the　rate　and　cycling　test.　According　to　the　relaxation　time　distribution　(DRT)　analysis,　the　porous　carbon　layer　on　the　CCF　surface　ensures　excellent　electrical　contact　between　silicon　and　the　Cu　foil　during　cycling,　facilitates　uniform　lithium　insertion　into　silicon,　prevents　uncontrolled　growth　of　the　SEI　layer,　and　guarantees　stable　battery　operation.　This　CCF　preparation　process　provides　a　promising　solution　to　mitigate　the　degradation　of　battery　performance　caused　by　silicon　expansion.　©　2025　American　Chemical　Society.
