▎ 摘　　要

NOVELTY - Anode material comprises: (a) a porous anode phase comprising silicon, where the porous phase has a porous-phase volumetric porosity of 5-80%; and (b) a first solid-state mediator layer outwardly disposed on the porous anode phase, the first solid-state mediator layer contains a lithium vanadium oxide material (LiaVbOc) (I) having a density of 2-4.5 g/cm3, where a is 0-10, b is 1-3, c is 1-9, and a, b, and c are selected to charge-balance (I), and (I) is capable of being reversibly lithiated. USE - The anode material is useful in lithium-ion batteries, which are useful for electrified transportation, portable electronics, and grid storage. ADVANTAGE - The anode material has long-cycle-life, high charge-storage capacity, high-capacitance, and high coulombic efficiency, and provides lithium-ion batteries with high capacity and high working potential. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: anode material comprising (a) a porous anode phase comprising a silicon-carbon composite containing silicon and carbon, where the porous anode phase has a porous-phase volumetric porosity of 5-80%, and (b) a first solid-state mediator layer outwardly disposed on the porous anode phase, the first solid-state mediator layer contains (I), (I) has a density of 2-4.5 g/cm3; and fabricating an anode material, comprising (i) providing a starting silicon-carbon composite containing silicon and carbon, (ii) blending the starting silicon-carbon composite with a thermoplastic polymer having a melting point of ≤ 300° C, thus generating a silicon-carbon-polymer composite, (iii) solution-coating the silicon-carbon-polymer composite with a sol-gel solution containing vanadium oxide, thus generating a silicon-carbon-polymer-vanadium oxide composite, (iv) thermally treating the silicon-carbon-polymer-vanadium oxide composite at an effective temperature to decompose and/or vaporize the thermoplastic polymer, thus generating a porous anode phase that is encapsulated by a shell containing crystallized vanadium oxide, (v) chemically lithiating the crystallized vanadium oxide with a lithium-containing reducing agent, thus generating (I), and (vi) recovering an anode material containing the porous anode phase encapsulated by (I).
