摘要： A capacitor having first and second electrodes and a scaffold dielectric. The scaffold dielectric comprises an insulating material with a plurality of longitudinal channels extending across the dielectric and filled with a dielectric paste comprising a porous material and an ion-comprising liquid within the pores of the porous material. The plurality of longitudinal channels are substantially parallel and the liquid comprising the dielectric paste generally has an ionic strength of at least 0.1. Capacitance results from the migrations of positive and negative ions in the confined liquid in response to an applied electric field. A method of supplying power to a load using the capacitor and a method of making the capacitor is additionally disclosed.
