World’s Smallest Battery
Research at Rice University has proved that the work done by Lithium-Ion batteries can also be done with very tiny batteries, which Rice University just produced.
The researchers have packed the energy produced by an entire Lithium-Ion battery into a small nanowire. This battery is 6 times thinner than a bacterium, 100 times thinner than a human hair and 60,000 times smaller than a AAA batttery.
The battery is basically a cross between a battery and a supercapacitor. Each battery is a nanowire and one half of it acts as anode and the other half acts as cathode.
The battery is made up of thousands of dense arrays. These arrays can be used to power medical devices, microscopic wireless networks, biological and chemical sensors and many other microscopic devices.
Arava Leela Mohana Reddy, a research scientist at Rice and co-author of the paper said, “The idea here is to fabricate nanowire energy storage devices with ultrathin separation between the electrodes. This affects the electrochemical behavior of the device. Our devices could be a very useful tool to probe nanoscale phenomenon.”
With such small batteries, electronic devices can be made much more slim. The microscopic devices now wont be needing a wire connected to them.
