scientists develop dissolving battery - lithium ion polymer battery
Scientists have developed a self.
A broken battery that can dissolve when exposed to heat or liquid. It delivers 2.
5 V, can power 15 minutes for desktop calculator.
It can be used to keep military secrets and environmental monitoring equipment confidential.
Reza Montazami, professor of mechanical engineering at Iowa State University, said it was the first practical transient battery.
Although this special battery cannot be used in the human body because it contains lithium, the researchers have been studying how the battery can dissolve innocently in the human body and prevent the pain of removal for several years.
Professor Montazami developed lithium.
The details of their findings were recently published in the Journal of Polymer Science, Part B: Polymer Physics.
It is 5mm in length, 1mm in thickness and 6mm in width, similar to commercial batteries in terms of composition, structure and electrochemical reaction.
It contains an anode, a cathode, and an electrolyte separator. based polymer.
When the battery falls into water, the polymer shell of the battery expands and the electrode breaks, causing the battery to dissolve.
However, it contains non-degraded nanoparticles, which means it will not dissolve completely.
The whole process takes about half an hour.
"Unlike traditional electronics designed to last for a long time, a key and unique attribute of transient electronics is to operate in typically short and good environments
Define the cycle and experience a fast, ideal, complete self
"Deconstructing and disappearing when briefly triggered," the scientific paper states . ".
While it is possible to make more powerful batteries, it will take longer to break down.
Dissolved batteries can play a role in helping to reduce waste from discarded electronics.
Researchers at the University of Illinois at Urbana
Champagne is developing electronic circuit boards that can dissolve in water.
According to Professor John Rogers of the university, once entering the landfill, the board may break in three to six months.
