Herein are described materials for a lithium ion anode, processes of manufacturing the lithium ion anode, and batteries that include the lithium ion anode. The materials can include a metal or metal alloy nanoparticulate carrying a solid electrolyte interface. The process can include admixing a lithium accepting material that is a metal or metal alloy nanoparticulate carrying a solid electrolyte interface with a conductive carbon; and then preparing a film of the admixture on an electrical substrate. The battery is assembled from the as manufactured lithium ion anode.

Engineered solid electrolyte interfaces on anode materials

Compositions, anodes, and batteries are described herein and incorporate particulates that feature carbon matrices having embedded therein a plurality of amorphous silicon nanoparticles. One embodiment includes a particulate composed of a porous carbon matrix and a plurality of amorphous silicon nanoparticles affixed to an interior surface of the porous carbon matrix and adjacent to an open volume that defines specific pores. Yet another embodiment is an anode active particulate that features a plurality of amorphous silicon nanoparticles affixed to interior surfaces of a porous carbon matrix, where the anode active particulate has a 'Standard-FCE' value that is about 5% greater than a 'Standard-FCE' value of an analogous anode active particle having crystalline silicon nanocrystals.

Amorphous silicon-carbon composites and improved first coulombic efficiency

Solid state compositions for use in an anode of a secondary battery, anodes, and lithium ion batteries are provided which include silicon carbide nanofibers, preferably carried in and reinforcing both an anode active material and a solid electrolyte. Methods of production and use are further described.

Formation of silicon-carbide reinforced carbon-silicon composites

The mechanochemically functionalizing silicon nanoparticles and the functionalized silicon nanoparticles are described. The processes include applying shear forces to silicon metal the presence of an alkane and thereby functionalizing the silicon with an alkyl-functionalization. The resulting product includes a plurality of silicon nanoparticles each carrying an alkyl-functionalization derived from an alkane.
