High energy density electrical energy storage devices
First Claim
1. A core-shell protonated material having a core material comprising a protonated compound having a perovskite crystal structure and at least one shell comprising a shell material in contact with the core material wherein the protonated compound has a proton concentration of at least about 0.01% by equivalent site occupation of ABO3 perovskite —
- O—
oxygen site occupation in a perovskite oxide particle ceramic of the core-shell compound.

Abstract
High electrical energy density storage devices are disclosed. The devices include electrochemical capacitors, electrolytic capacitors, hybrid electrochemical-electrolytic capacitors, secondary batteries and batcaps. Advantageously, the energy storage devices may employ core-shell protonated perovskite submicron or nano particles in composite films that have one or more shell coatings on a protonated perovskite core particle, proton bearing and proton conductive. The shells may be formed of proton barrier materials as well as of electrochemically active materials in various configurations.
