The　interfacial　instability　and　poor　rate　performance　caused　by　the　drastic　volume　expansion　hinder　the　further　application　of　micron-silicon　(μSi)　anode.　To　this　end,　this　work　designs　a　CNT/polymer　conducting　network　(PAA-TA-CMC/CNT)　that　balances　the　dense　coating　effect　of　carbon　nanotubes　and　high　strength.　In　this　CNT/polymer　conducting　network,　carboxymethyl　cellulose　(CMC)　and　carboxylated　multi-walled　carbon　nanotubes　(CNT)　form　a　dense　conductive　network　through　self-assembly,　achieving　uniform　coating　of　CNT　on　μSi　particles.　The　polymeric　binder　formulated　from　polyacrylic　acid　(PAA)　and　tannic　acid　(TA)　leverages　a　range　of　interactions,　including　covalent　bonds　and　hydrogen　bonds,　to　not　only　ensure　the　robust　attachment　of　the　conductive　coating　onto　μSi　but　also　significantly　bolster　the　overall　strength　of　the　electrode.　As　anticipated,　the　μSi　anode,　facilitated　by　the　CNT/polymer　conducting　network,　retains　a　substantial　reversible　capacity　of　1885.4　mAh/g　after　undergoing　300　cycles　(2　A/g)　and　demonstrated　excellent　stability　even　after　350　cycles　at　a　high　rate　of　4　A/g.　Furthermore,　this　CNT/polymer　conducting　network　can　also　enhance　the　rate　capability　and　long-cycle　life　of　SiOx　anodes　(1426.3　mAh/g　over　300　cycles　at　2　A/g,　891.6　mAh/g　over　1000　cycles　at　4　A/g).　This　design　strategy,　which　incorporates　both　dense　CNT　coating　and　high-strength　conductive　polymers,　offers　a　viable　approach　to　improving　the　performance　of　high-capacity　alloy-based　anode　materials.　©　2025　Elsevier　B.V.
