Scientists Have Made A Self-Destructing, Dissolvable Battery
The value of a battery is often considered in terms of its battery life. A battery that never dies? Sounds great. But the 2016 invention of a short-term, self-destructing battery is making waves. Iowa State University mechanical engineering professor Reza Montazami lead a team of researchers in creating what they are calling the first practical transient battery.
Perhaps the biggest impact this technology may have is on the environment. Self-destructing batteries that almost completely dissolve (translation: all that's left after it dissolves is nanoparticles that do not degrade) leave much less waste for landfills. This new push in transient electronics aims to create batteries and devices that operate within a small time frame before self-destructing. This could be useful in secretive military conditions, and in medical devices that would otherwise require an operation to remove a battery. Learn more in the video below.
