Abstract
Energy storage apparatus comprising: a porous conductor substrate, an insulator layer in contact with inner surfaces of the porous conductor substrate, and a conductor layer in contact with outer surfaces of the insulator layer.
Claims24
An energy storage apparatus comprising:
- a porous conductor substrate defining a network of interconnected voids connected to an outer surface of the porous conductor substrate and defining inner surfaces of the porous conductor substrate;
- an insulator layer in contact with inner surfaces of the porous conductor substrate;
- and
- a conductor layer in contact with outer surfaces of the insulator layer;
- wherein:
- the insulator layer comprises a first electrical storage layer operative to store energy in a polarized configuration when a voltage is applied across the porous conductor substrate and conductor layer;
- and
- the insulator layer further comprises a second electrical storage layer configured to change between an electrically insulative configuration and an electrically conductive configuration, with transition from the electrically insulative configuration to the electrically conductive configuration occurring in response to application of a voltage exceeding a threshold voltage across the porous conductor substrate and the conductor layer, wherein the threshold voltage is at least 100 volts.

An energy storage apparatus comprising:
- first and second spaced conductor parts operative to generate a voltage therebetween above a threshold voltage, wherein the threshold voltage is at least 100 volts;
- a first electrical storage part located between the first and second spaced conductor parts, the first electrical storage part being operative to store energy in a polarized configuration when the voltage is applied across the first and second spaced conductor parts;
- and
- a second electrical storage part located between the first electrical storage part and one of the first and second spaced conductor parts, the second electrical storage part being configured to change between an electrically insulative configuration and an electrically conductive configuration, with transition from the electrically insulative configuration to the electrically conductive configuration occurring in response to application of the voltage across the first and second spaced conductor parts;
- and
- wherein the apparatus is configured such that:
- before energy is stored in the first electrical storage part by polarization, work must be done to convert the second electrical storage part from the electrically insulative configuration to the electrically conductive configuration;
- and
- the energy stored by converting the second electrical storage part from the electrically insulative configuration to the electrically conductive configuration is released as the second electrical storage part converts back to the electrically insulative configuration during a discharging stage.
