{"product_id":"ccbeafc70","title":"Fullerene C70 Powder (\u003e99.0%) as Conductive Battery Electrode Additive, 1 g\/bottle, CCBEAFC70","description":"\u003cp\u003eFullerene C70 powder is an ellipsoidal 0D carbon nanomaterial used in battery systems as a functional conductive and interfacial additive. While conventional carbon additives (such as Carbon Black Super P, MWCNTs, and Graphene) are used in bulk to construct long-range conductive percolation pathways, C70 acts as a sub-nanometer electronic conduit, solid-electrolyte interphase (SEI) stabilizer, and radical scavenger\u003c\/p\u003e\n\u003cp\u003eThe main features of the Fullerene C70 are: (1) \u003cstrong\u003eSub-Nanometer Interstitial Electronic Hopping\u003c\/strong\u003e: With molecular dimensions of ~ 1.06nm * 0.78 nm, C70 easily penetrates sub-nanometer grain boundaries and porous active material structures (e.g., SPAN Li-S cathodes, hard carbon, or high-nickel layered oxides) where larger carbon blacks and CNT bundles cannot reach. It facilitates local electron hopping across particle contacts. (2) \u003cstrong\u003eFulleride SEI Formation \u0026amp; Dendrite Suppression\u003c\/strong\u003e: C70exhibits strong electron affinity (LUMO ~ -4.0 eV) and undergoes multi-electron reduction. When added to the electrode surface or liquid electrolyte, it reduces at low potentials to form uniform, lithiated\/sodiated fullerides (LixC70 \/ NaxC70). This creates a mechanically robust, highly ion-conductive SEI that homogenizes electric fields and suppresses dendrite formation on alkali metal anodes. (3) \u003cstrong\u003eRadical Trapping \u0026amp; Cathode Protection\u003c\/strong\u003e: Operating as a molecular \"radical sponge,\" C70 captures reactive oxygen species and decomposition radicals generated at high cutoff voltages (\u0026gt;4.3 V), mitigating electrolyte degradation and transition metal dissolution. (4) \u003cstrong\u003ePolysulfide Anchoring in Li-S \/ Na-S\u003c\/strong\u003e: The curvature and electron delocalization of the C70 cage promote physical and chemical adsorption of soluble intermediate polysulfides (Li2Sx), reducing shuttle-effect capacity decay.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 172px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCBEAFC70 (C-CBEA-FC70)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e115383-22-7\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eMolar Mass\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e840.78 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.0%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 10px;\"\u003e\u003cem\u003ePowder Color\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 10px;\"\u003e\n\u003cp\u003e\u003cspan\u003eBrown or black powder\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e1 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the Fullerene C70 powder in a dry place (glovebox is the best option). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/pubs.acs.org\/nalefd\/article-abstract\/19\/12\/8780\/511904\/Nitrofullerene-a-C60-based-Bifunctional-Additive?redirectedFrom=fulltext\"\u003e\u003cspan\u003eZ.
