Researchers led by professor Reza Montazami at Iowa State University's mechanical engineering have created the world's first transient battery. It delivers 2.5 volts and can power a desktop calculator for 15 minutes. Yet, expose it to significant heat (such as burning) or simply drop it in water or a water-based fluid and it dissolves away to almost nothing.

The battery is intended to power military devices, or long-term sensor-net probes, and is a way of rendering the devices non-functional if they are damaged or vandilised, preventing third parties from using the batteries or their parent devices for purposes not intended.

While this particular battery could not be used in the human body as it contain lithium, researchers have been examining how batteries could dissolve harmlessly within the human body, and prevent the pain of removal, for several years.
