Abstract
Official abstract text for this publication.
Pillared particles of silicon or silicon-comprising material and a method of fabricating the same are disclosed. These particles may be used to create both a composite anode structure with a polymer binder, a conductive additive and a metal foil current collector, and an electrode structure. The structure of the particles overcomes the problems of charge/discharge capacity loss.
First claim
Opening claim text (preview).
The invention claimed is: 1. A plurality of discrete particles, wherein each particle comprises silicon, including a silicon-comprising particle core, and a plurality of silicon-comprising pillars extending outwardly therefrom from a first end to a second end, wherein each pillar in the plurality of pillars is attached to the core at the first end of the pillar, and the second end of each pillar is an unattached free end, wherein in each particle, the fraction of the surface area o…
