Abstract
An intercalation electrode includes an electron current collector and graphene planes deposited normal to the surface of the current collector substrate. The graphene planes are deposited on the current collector substrate from a carbon-precursor gas using, for example, chemical vapor deposition. In an embodiment of an anode for a lithium-ion battery, the graphene planes are intercalated with lithium atoms. A lithium-ion battery may include this anode, a cathode, and a non-aqueous electrolyte. In repeated charging and discharging of the anode, lithium atoms and ions are readily transported between the graphene planes of the anode and the electrolyte.
