India has successfully developed new green and low-cost supercapacitors

In recent years, as a new energy storage device with excellent properties, supercapacitors have attracted a lot of attention
.
Supercapacitors have the characteristics
of ultra-high charge and discharge rate, excellent stability, long service life and high energy density.
In the not-too-distant future, supercapacitors could fully charge mobile phones in seconds and electric cars in minutes
.

Although supercapacitors have faster charging speed and stronger endurance than traditional batteries, supercapacitors occupy much larger volumes and weight than batteries of the same capacity
.
Therefore, many scientists are committed to developing green and low-cost high-performance lightweight supercapacitors
.

A few days ago, S.
N.
from India.
Two scholars at the Bose National Basic Science Research Center have developed a new supercapacitor with a composite nanostructure that has superior performance
over existing non-composite supercapacitor electrodes.
Since nickel oxide and iron oxide are cost-effective and environmentally friendly materials, they meet the requirements of
green low-cost supercapacitors.
