Researchers from the Lowa State University has developed a lithium-ion battery which is having a capacity of dissolving when dropped in water and making itself self-destruct.
This battery is having a capacity of dissolving within a duration of 30 minutes.
This advancement can lead to the development of ‘transient electronics’ or the self-destructing devices which are designed for keeping the military secrets out of enemy hands.
Device: Promoting Transient Electronics
This device could also save the pain of patients of removing a medical device and allowing the environmental sensors for washing them away in rain.
For making such devices possible is the prime goal of this newer field of study called as the ‘transient electronics’.
This devices could possibly perform variety of functions until they are exposed to light, heat or liquid triggers their own destruction.
Latest development which is also including Reza Montazami from the lowa State University from US is a kind of self-destructing lithium-ion battery which is capable of delivering 2.5 volts and then dissolving or dissipating in about 30 minutes when they are dropped in water.
This particular battery can power a desktop calculator for a duration of about 15 minutes. It is being the first transient battery which is demonstrating the power, stability and shelf life for the practical use.
Researchers adding to the same says, “Unlike conventional electronics that are designed to last for extensive periods of time, a key and unique attribute of transient electronics is to operate over a typically short and well-defined period, and undergo fast and, ideally, complete self-deconstruction and vanish when transiency is triggered.”

Compact and Dissolvable Battery in Water:
Montazami adding to the same says, “Any device without a transient power source is not really transient. This is a battery with all the working components.”
This particular transient battery is made up of eight layers which is including an anode, a cathode and even an electrolyte separator which are all being wrapped up in the two layers of polyvinyl alcohol based polymer.
Battery itself is quite tiny and is about 1 mm thick, 5 millimeters long and about 6 millimeters wide.
Battery components, structure and electrochemical reaction are all being very close to the commercially developed battery.
When anyone drops the battery in water, polymer casing of the battery swells and breaks apart the electrodes which further dissolves away.
According to Montazami, battery doesn’t completely disappear. It is containing nanoparticles which doesn’t degrade itself but they disperse as the battery casing breaks the electrodes apart.
Larger batteries with larger capacities could provide more power, but they will be lasting longer to self-destruct themselves. Findings of the same is published in Journal of Polymer Science, Part B: Polymer Physics.
