Dissolving battery technology to change energy game forever?
It delivers 2.5 volts, can power a calculator for 15 minutes, and then disappears when it's dropped in water.
Scientists have developed an all-new dissolving battery which could change the energy game completely, they say.
Iowa State University mechanical engineering professor Reza Montazami says it's the first practical transient battery.
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.
Nanotechnologist and science educator Michelle Dickinson joined Paul Henry this morning to discuss the new technology.
