Binders　play　a　key　role　in　maintaining　the　integrity　of　high-capacity　silicon　anodes,　which　otherwise　experience　serious　capacity　decay　during　cycling　caused　by　huge　volume　variation　of　the　silicon.　With　an　aim　to　developing　a　highly　efficient　polymeric　binder　to　mitigate　this　capacity　decay,　we　present　a　novel　binder　synthesized　from　polyacrylic　acid　(PAA)　and　polymerized　β-cyclodextrin　(β-CDp)　for　Si　anodes　for　the　lithium-ion　batteries.　This　PAA-β-CDp　binder　has　a　3D　network　structure,　which　provides　strong　adhesion　between　the　active　material　and　the　current　collector.　PAA-β-CDp　binder　makes　silicon　anode　achieve　a　specific　capacity　of　2326.4　mAhg−1　at　the　current　density　of　0.2　A　g−1　with　a　capacity　retention　of　64.6%　after　100　cycles.　The　experimental　results　show　that　the　PAA-β-CDp　binder　can　effectively　mitigate　the　huge　volume　change　and　improve　the　capacity　and　cycling　performance　of　Si　anodes.　©　2022
