Abstract: A lithium-ion battery includes an electrode with microscale channels formed in the electrode material and a nanoscale conformal coating over the electrode material. The channels promote Li-ion transport to the interior of the electrode during charging, and the coating acts as an artificial solid electrolyte interphase (SEI) in place of the SEI that is typically formed during initial charge cycles of a Li-ion battery. The coating can be selected to have a lower impedance than a naturally formed SEI and can be formed in a more controlled manner prior to cell assembly. Cold-charging performance of the resulting battery is enhanced more than would be expected by the individual contributions of the channels and the coating.
