Ultracapacitor electrodes having an enhanced electrolyte-accessible surface area are provided. Such electrodes can include a porous substrate having a solution side and a collector side, the collector side operable to couple to a current collector and the solution side positioned to interact with an electrolytic solution when in use. The electrode can also include a conductive coating formed on the solution side of the porous substrate. The coating can have a first side positioned to interact with an electrolytic solution when in use and a second side opposite the first side. The coating can have discontinuous regions that allow access of an electrolyte solution to the second side during use to enhance electrolyte-accessible surface area of the conductive coating.
