Abstract
A battery is disclosed that includes two contact areas, an electrolyte, and a conductivity mechanism to increase electron conductivity internal to the battery between the two contact areas that, in turn, deactivates the battery. In one embodiment, the conductivity mechanism is triggered external to the battery. In another embodiment, the conductivity mechanism utilizes deactivator material to increase electron conductivity through the electrolyte to deactivate the battery. In yet another embodiment, the conductivity mechanism creates multiple shorts between the two contact areas to deactivate the battery.
Claims23
A system comprising:
- a battery comprising:
- a first contact area and a second contact area, wherein the first contact area is negatively charged relative to the second contact area;
- an electrolyte that couples to the first contact area and to the second contact area, wherein the electrolyte suppresses electron flow internal to the battery between the first contact area and the second contact area and enables ion flow internal to the battery between the first contact area and the second contact area:
- and
- a conductivity mechanism to increase electron conductivity between the first contact area and the second contact area internal to the battery.
A system comprising:
- one or more system components that consume power;
- a battery pack that provides power to the one or more system components, wherein the battery pack comprises:
- a battery comprising:
- a first contact area and a second contact area, wherein the first contact area is negatively charged relative to the second contact
- an electrolyte that couples to the first contact area and to the second contact area, wherein the electrolyte suppresses electron flow internal to the battery between the first contact area and the second contact area and enables ion flow internal to the battery between the first contact area and the second contact area:
- and
- a conductivity mechanism for increasing electron conductivity between the first contact area and the second contact area internal to the battery;
- and
- a deactivator mechanism that is invoked external to the battery, wherein, when invoked, triggers the conductivity mechanism to increase the electron conductivity between the first contact area and the second contact area internal to the battery.
A method for producing a battery, the method comprising:
- including a first contact area and a second contact area in the battery, wherein the first contact area is negatively charged relative to the second
- including an electrolyte in the battery that couples to the first contact area and to the second contact area, wherein the electrolyte suppresses electron flow internal to the battery between the first contact area and the second contact area and enables ion flow internal to the battery between the first contact area and the second contact area:
- and
- including a conductivity mechanism in the battery to increase electron conductivity between the first contact area and the second contact area internal to the battery.
