A group of researchers has developed a portable supercapacitor that can be charged using light in a collaborative project involving institutions in India and South Korea.
The invention holds promise for replacing the conventional lithion-ion batteries in portable and wearable devices such as smartphones, tablets, laptops and smartwatches.
The study, which has been published in peer-reviewed journal Journal of Power Sources, was undertaken by researchers from University College, Thiruvananthapuram; IIT Guwahati; Gwangju Institute of Science and Technology; Korea Institute of Energy Technology; and Chonnam National University in South Korea.
