Abstract
Official abstract text for this publication.
Described herein are improved composite anodes and lithium-ion batteries made therefrom. Further described are methods of making and using the improved anodes and batteries. In general, the anodes include a porous composite having a plurality of agglomerated nanocomposites. At least one of the plurality of agglomerated nanocomposites is formed from a dendritic particle, which is a three-dimensional, randomly-ordered assembly of nanoparticles of an electrically conducting material and a plurality of discrete non-porous nanoparticles of a non-carbon Group 4A element or mixture thereof disposed on a surface of the dendritic particle. At least one nanocomposite of the plurality of agglomerated nanocomposites has at least a portion of its dendritic particle in electrical communication with at least a portion of a dendritic particle of an adjacent nanocomposite in the plurality of agglomerated nanocomposites.
First claim
Opening claim text (preview).
What is claimed is: 1 . An anode, comprising: a porous composite comprising a plurality of agglomerated nanocomposites, wherein each of the plurality of nanocomposites comprises: a dendritic particle comprising a three-dimensional, randomly-ordered assembly of nanoparticles of an electrically conducting material; and a plurality of discrete non-porous nanoparticles of a non-carbon Group 4A element or mixture thereof disposed on a surface of the dendritic particle; and wherein each nanocomposite of the plurality of agglomerated nanocomposites has at least a portion of the dendritic particle in electrical communication with at least a portion of a dendritic particle of an adjacent nanocomposite in the plurality of agglomerated nanocomposites.
