The biggest clampdown in many electrical devices is energy storage, or recharging time, or capacity of the battery. In future, you may see supercapacitors with high power energy storage capacity that enable effective and rapid recharging of electrical devices. Due to high costs and hitch of producing some components, we are unable to see the adoption of technology. Nevertheless, scientists of the Oregon State University enabled to produce cheaper supercapacitors in large quantities.
How could they succeed?
The supercapacitors were made by exploiting cellulose present in trees which could make high quality carbon electrodes.
Xiulei Ji, the assistant professor of chemistry working with OSU, stated that,
"We take affordable wood and then turn it into a dear product"
The chemists of OSU discovered an effortless process just by using basic reaction which could turn the cellulose to 'nitrogen-doped and nanoporous carbon membranes' which are used as electrodes in the supercapacitors.
Did You Know?
The most inexhaustible organic polymer on the Earth is cellulose. By heating it in the presence of ammonia, yields a quick and economical energy storage device.
Nanoporous carbon membranes are not only used in supercapacitors, but also used in environmental filtering and water treatment. So, this process decreases the costs and enhances the adoption of technology.
Xiulei Ji said that,
"There are wider uses of supercapacitors in the world. But now, the field is restricted by cost. If we start using this, making these devices is simple and inexpensive and have many benefits."
The other advantage of this process is that, it is 'environmentally benign' as it gives methane as a byproduct and used as fuel or can also be used in other industrial purposes.
