Abstract
The present invention relates to nanostructured materials (including nanowires) for use in batteries. Exemplary materials include carbon-comprising, Si-based nanostructures, nanostructured materials disposed on carbon-based substrates, and nanostructures comprising nanoscale scaffolds. The present invention also provides methods of preparing battery electrodes, and batteries, using the nanostructured materials.
Claims30
A battery slurry additive comprising:
- a plurality of Si-based nanoscale scaffolds disposed on particles of a carbon-based powder substrate comprising carbon black or graphite and forming a porous network,
- wherein the particles of the carbon-based powder substrate are between 5 microns and 50 microns,
- wherein the plurality of Si-based nanoscale scaffolds have a core-shell structure,
- wherein the plurality of Si-based nanoscale scaffolds comprise nanowires with at least one cross-sectional dimension less than 100 nm,
- wherein said porous network comprises mesopores and macropores, and
- wherein said porous network can accommodate volume changes associated with lithiation and delithiation during repeated charge/discharge cycles of a battery anode electrode.
