Standard lithium-ion batteries use graphite anodes that are capable of holding only a limited amount of charged lithium particles. The graphite anodes' limited capacity is chiefly responsible for the relatively brief charge life of lithium-ion batteries. Replacing the graphite anodes with silicon nanowires would increase the battery's charge storage capacity, Stanford researchers found.

"Silicon is an attractive anode material for lithium batteries because it has a low discharge potential and the highest known theoretical charge capacity," the report says.
