A lithium- or lithium-ion electrochemical cell of the present invention comprises a lithium-containing cathode, an anode, and a non-aqueous lithium-containing electrolyte therebetween; wherein one or more of the anode and/or the cathode comprises at least one particulate carbon material comprising nanoparticles of the surface of individual carbon particles, wherein the nanoparticles are selected from one or more of (a) a metal oxide or sulfide comprising one or more metal ions selected from the group consisting of Ti, Fe, Mn, Co, Ni, Mo, W, In, and Sn; (b) one or more metals selected from the group consisting of Ti, Fe, Co, Mg, Al, Ga, In, and Sn; and (c) one or more metaloid selected from the group consisting of B, Si, Ge, and Sb.
A lithium or lithium-ion electrochemical cell comprising a cathode, an anode, and a non-aqueous lithium-containing electrolyte therebetween, wherein one or more of the anode and/or the cathode comprises at least one particulate carbon material comprising nanoparticles on the surface of individual particles of the carbon, and wherein the nanoparticles comprise at least one material selected from the group consisting of:
A method of fabricating a particulate carbon material comprising nanoparticles on the surface of individual carbon particles carbon particles, the method comprising sonicating a slurry of carbon particles in a solvent in the presence of a metal compound, a metalloid compound, or a combination thereof, optionally under an atmosphere;
