▎ 摘　　要

NOVELTY - Particulate silicon-carbon composite comprises silicon and carbon, where the carbon comprises (i) a porous carbon scaffold comprising (a) amorphous carbon, (b) a pore volume having greater than 70% of the pore volume resides of a diameter of less than 2 nm, and (c) a DPv90 less than 50 nm. The silicon comprises amorphous, nano-sized silicon embedded within the pore volume of the carbon scaffold. USE - As an anode material for energy storage devices, e.g. lithium ion batteries, lead acid automobile batteries, and hybrid electric vehicles. ADVANTAGE - The method enables to produce composite material that has improved performance stems from disordered nature of graphene layers that allows lithium-ions to intercalate on either side of graphene plane allowing for theoretically double the stoichiometric content of lithium ions versus crystalline graphite. DETAILED DESCRIPTION - Particulate silicon-carbon composite comprises silicon and carbon, where the carbon comprises (i) a porous carbon scaffold comprising (a) amorphous carbon, (b) a pore volume having greater than 70% of the pore volume resides of a diameter of less than 2 nm, and (c) a DPv90 less than 50 nm. The silicon comprises amorphous, nano-sized silicon embedded within the pore volume of the carbon scaffold. The composite comprises (ai) a surface area less than 30 m2/g, (iia) a capacity of greater than 1300 mA/g, (iiia) an average Coulombic efficiency of greater than or equal to0.998, as measured in a half cell, (iva) a Z of less than 10, where Z=1.875x((M1100-M)/M1100)x100%, and M1100 is a mass of the silicon-carbon composite at 1100degrees Celsius and M is the minimum mass of the silicon-carbon composite between 800-1100degrees Celsius, when the silicon-carbon composite is heated under air of 25-1100degrees Celsius, as determined by thermogravimetric analysis, and (va) a phi of greater than or equal to0.15, where phi = (Max peak height dQ/dV in Regime I)/(Max peak height dQ/dV in Regime III), wherein dQ/dV is measured in a half-cell coin cell, and Regime I is 0.8V-0.4V and Regime III is 0.15-0 V.
