Chennai scientists develop low -cost supercapacitors using rusk crumb
Scientists have used cake rusk left to develop to low – cost supercapacitors – a electronic component that is used to storage charge and has a wide range of applications i everyday modern devices.
Owing to the ever growing energy demand , electrochamical energy storage systems with higher energy and power densities such as lithium – ion batteries and supercapacitors have attracted tremendous attention in recent years.
The researchres from SRM Institute of science and technology in Chennai wanted to create low – cost alternatives by recycling waste materials and converting them into products that have high demand.
For a study published inthe journal microporous and mesoporous materials,they collected waste cake rusk crumbs from local bakeries and heated them in nitrogen gas to obtain highly porous carbon with very high surface area.
“The carbon materials obtained from Indian cake rusk have very high porosity,surface area and pore volumes which are superuor then the other waste materilas investigated ,”M sasindharan,pricipal investigator of study.
Supercapacitors are devices that can store and deliver charge much faster than batteries,and tolarate many more charge and discharge cucles than rechargeable batteries.
It has widespread application from a rage of devices such as smartphones,laptops and portable media players.They are also used as voltage stabilisers,in medical devices and as energy harvesters.
The device fabricated by the researchers can light up few LED bilbs.in future,the materials may be extended high end applications,researchres said.
Sasidharan said that the research may bring down the cost of supercapacitors by 70 percent , since the raw materials are inexpensive.
