In Researchers led by Pulickel M. Ajayan at Rice University, USA, have managed to package lithium ion batteries into a single nanowire. Pulickel M. Ajayan did his B. Tech in metallurgical engineering from Banaras Hindu University in 1985, India and Ph.D. from Northwestern University US in 1989.
A nanometre is only one billionth of a metre, if a source of power can be packed in such a small space, then mankind could have found the valuable power for new generations of nanoelectronics. The teams experimental batteries are about 50 micrometres tall, as thick as a human hair and almost invisible when viewed edge-on.
In a university statement, Arava Leela Mohana Reddy, study co-author and research scientist, said, The idea here is to fabricate nanowire energy storage devices with ultra-thin separation between the electrodes. These batteries are scalable, as theoretically any nanowire energy storage device can be as long and as wide as the template allows.
A reasonably good capacity is being detected from nanowire devices. The researchers are fine-tuning the materials to increase their ability to repeatedly charge and discharge, which now drops off after about 20 cycles.
