Abstract
Composites of silicon and various porous scaffold materials, such as carbon material comprising micro-, meso- and/or macropores, and methods for manufacturing the same are provided. The compositions find utility in various applications, including electrical energy storage electrodes and devices comprising the same.
Claims30
A composite comprising a porous carbon scaffold and silicon, wherein the composite comprises from 15 to 85% silicon by weight and a nitrogen-inaccessible volume ranging from 0.05 to 0.5 cm3/g, and wherein the composite comprises a plurality of particles having a particle skeletal density ranging from 1.5 to 2.2 g/cm3, as measured by helium pycnometry.
