A new self-destructing battery can power a simple electronic device for up to 15 minutes
and then dissolve in water. It could pave the way for so-called transient power sources for scientific instruments or tools of espionage, according to a new study.
Engineers have developed a novel variety of battery capable of powering a simple electronic device, such as a four-function calculator, and then dissolving in water in half an hour. The new transient battery represents a marked improvement in voltage and disintegration time over its predecessors, the researchers said.
The lithium-ion battery, the first transient battery of its kind, is "very similar to a conventional battery," study co-author Reza Montazami, who heads the Advanced Materials Lab at Iowa State University, told Live Science. [Top 10 Inventions That Changed the World]
