Abstract
A photonic enhanced battery is provided. A rechargeable battery can include one or more cells that incorporate one or more optical waveguides that deliver electromagnetic radiation into the cell. The electromagnetic radiation can improve ionic transport, heat the cell, suppress dendrite formation or growth and/or enhance micro-gap conductivity. An optical waveguide may be coupled at an edge of the cell's separator to direct the electromagnetic radiation between the cell's electrodes.
Claims20
A photonic enhanced battery for inducing an evanescent field to inhibit formation of dendrites comprising:
- a cathode;
- an anode;
- a separator between the cathode and the anode;
- an optical waveguide having a first end and a second end, the first end being in direct optical contact with an edge of the separator;
- and
- an electromagnetic radiation source that is configured to output electromagnetic radiation comprising one or more of infrared, visible and ultraviolet light, into the second end of the optical waveguide, wherein the optical waveguide is configured to cause the electromagnetic radiation to be carried through the optical waveguide and emitted from the first end through the edge of the separator for delivery into the separator to thereby cause the electromagnetic radiation to propagate through the separator to induce an evanescent field at the anode due to the electromagnetic radiation reflecting off an interface between the anode and the separator.
A photonic enhanced battery for inducing an evanescent field to inhibit formation of dendrites comprising:
- at least one cell, each cell comprising:
- a cathode;
- an anode;
- a separator between the cathode and the anode;
- and
- an optical waveguide having a first end and a second end, the first end being in direct optical contact with an edge of the separator;
- and
- at least one electromagnetic radiation source that is configured to output electromagnetic radiation, comprising one or more of infrared, visible and ultraviolet light, into the second end of each optical waveguide, wherein each optical waveguide is configured to cause the electromagnetic radiation to be carried through the optical waveguide and emitted from the first end through the edge of the respective separator for delivery into the respective separator to thereby cause the electromagnetic radiation to propagate through the respective separator to induce an evanescent field at the respective anode due to the electromagnetic radiation reflecting off an interface between the respective anode and the respective separator.
A method for controlling dendrites within a battery cell, the method comprising:
- detecting that the battery cell is being charged, the battery cell comprising:
- a cathode;
- an anode;
- a separator between the cathode and the anode;
- and
- an optical waveguide having a first end and a second end, the first end being in direct optical contact with an edge of the separator;
- activating an electromagnetic radiation source to output electromagnetic radiation, comprising one or more of infrared, visible and ultraviolet light, into the second end of the optical waveguide, wherein the optical waveguide is configured to cause the electromagnetic radiation to be carried through the optical waveguide and emitted from the first end through the edge of the separator for delivery into the separator while the battery cell is being charged to thereby cause the electromagnetic radiation to propagate through the separator to induce an evanescent field at the anode due to the electromagnetic radiation reflecting off an interface between the anode and the separator.
