Abstract
In one aspect, energy storage devices and methods are disclosed that include (preferably in order): a cationic electrode cover layer, a cationic electrode, a cationic exchange polymer electrolyte layer, a separation dielectric layer, an anionic exchange polymer electrolyte layer, an anionic electrode, and an anionic electrode cover layer. In certain embodiments, the device is configured to be initially placed in an ionized state, and optionally, can be configured to be further charged to store energy in an electrostatic mode. In another aspect, ionic solid dielectric materials, energy storage devices including ionic solid dielectric materials, and methods of making and using such materials and devices are disclosed herein.
