I don't know if you ever thought that you might need one battery that dissolves in water, but Iowa State University researchers thought that such a device would be useful for something, so they created the first battery that dissolves in water, no less than 30 minutes being necessary to accomplish this.
We are talking about a lithium-ion battery that it has enough energy to keep a computer running for 15 minutes, it then needs 30 minutes to completely dissolve in water, the achievement itself being an impressive one, even if the practical applications are as limited as possible.
The battery is one millimeter thick and 5 millimeters long, its case being made of a composite polymer that swells and breaks after being placed in water, so we are talking about a very small battery that can be destroyed very quickly and it is perfect for spies who need quick energy for a gadget.
For now, the battery that dissolves in water is in the first stages of development and it will take some time before it will be available for purchase on a large scale, its size will be increased along with the capacity to store energy, so it remains to seen what the researchers will have prepared in the end.
Self-destructing electronic devices could keep military secrets out of enemy hands. Or they could save patients the pain of removing a medical device. Or, they could allow environmental sensors to wash away in the rain. The latest development from his lab is a self-destructing, lithium-ion battery capable of delivering 2.5 volts and dissolving or dissipating in 30 minutes when dropped in water. The battery can power a desktop computer for about 15 minutes.
