Process for Making Silicon-based Anode for Li-Ion Battery

Abstract Conventional Li-ion batteries use graphite anodes, which have a theoretical specific capacity of 372 mAh/g, which limits their application for high capacity energy storage devices. Silicon has been tried because of its high theoretical specific capacity (on the order of 4200 mAh/g) but the stress created due to volume expansion during intercalation...

Lithium Ion Battery Anode Containing Carbon Coated Silicon and Production Process

Abstract A facile route to suppress the capacity fading because of the pulverization and uncontrolled growth of solid electrolyte interphase in silicon anodes is described. In this new approach, a mixture consisting of milled silicon particles and superconducting carbon particles is dispersed with a liquid precursor of carbon (Furfuryl alcohol). Silicon...
