{"product_id":"clibabdnsi","title":"Boron-Doped Silicon (Si) Nanopowder for Li-Ion Battery Anode, 10 g\/bottle, CLIBABDnSi","description":"\u003cp\u003eBoron-doped silicon (Si) nanopowder (D50 = 50-100 nm) is an advanced high-capacity anode material engineered to overcome the inherent semiconductor limitations of pristine silicon. The main functions of the boron doping in Si nanopowder are: (1) \u003cstrong\u003eEnhanced Electronic Conductivity\u003c\/strong\u003e: Substituting silicon atoms with boron (a group III acceptor) creates electron holes within the lattice, increasing electronic conductivity by several orders of magnitude compared to intrinsic silicon. This minimizes internal electrical resistance and eliminates the need for excessive conductive carbon additives. (2) \u003cstrong\u003eImproved Lithiation Kinetics\u003c\/strong\u003e: Facilitates uniform electron transfer across the active particle network, reducing local polarization and enabling faster lithium-ion insertion\/extraction during high-rate charge and discharge cycles. (3) \u003cstrong\u003eVolumetric Strain Management\u003c\/strong\u003e: While retaining the ultra-high theoretical capacity of silicon (~ 3,579 mAh\/g), the boron-doped crystal lattice demonstrates enhanced structural resilience against the severe volumetric expansion (\u0026gt; 300-400%) experienced during deep lithiation.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%; height: 345.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.621%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCLIBABDnSi (C-LIB-A-BDnSi)\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: 33.621%; height: 35.6px;\"\u003e\u003cem\u003eParticle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e50-100 nm\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: 33.621%; height: 35.6px;\"\u003e\u003cem\u003eBoron Content\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e0.5-5 at% (atomic ratio, adjustable)\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: 33.621%; height: 35.6px;\"\u003e\u003cem\u003eImpurity Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%; height: 35.6px;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003eOxygen level: \u0026lt;1 wt%\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eMagnetic level: \u0026lt;10 ppm \u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.621%;\"\u003e\u003cem\u003eElectrical Conductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e~9*10^(-6) S\/cm\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.621%;\"\u003e\u003cem\u003eCompaction Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e0.5668 g\/cm3\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.621%;\"\u003e\u003cem\u003eMain Functions\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e(1) Increase electronic conductivity\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e(2) Suppress the volume expansion\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e(3) Optimize the SEI by passivating the Si surface\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.621%;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9835%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e10 g\/bottle\u003c\/div\u003e\n\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\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/pubs.rsc.org\/ta\/article-abstract\/6\/7\/3022\/588490\/Boron-doped-porous-Si-anode-materials-with-high\"\u003e\u003cspan\u003eM.
