Abstract

In one embodiment a charge storage device includes first ( 110 ) and second ( 120 ) electrically conductive structures separated from each other by a separator ( 130 ). At least one of the first and second electrically conductive structures includes a porous structure containing multiple channels ( 111, 121 ). Each one of the channels has an opening ( 112, 122 ) to a surface ( 115, 125 ) of the porous structure. In another embodiment the charge storage device includes multiple nanostructures ( 610 ) and an electrolyte ( 650 ) in physical contact with at least some of the nanostructures. A material ( 615 ) having a dielectric constant of at least 3.9 may be located between the electrolyte and the nanostructures.
