Indian Institute of Technology Guwahati develops pseudocapacitive hydrogels

GUWAHATI: A group of researchers from the Indian Institute of Technology, Guwahati (IIT) has successfully developed hydrogel-based electrodes that could enhance the performance of an energy storage device.

The research group at the Department of Physics, IIT Guwahati, led by Dr Uday Narayan Maiti, in collaboration with Prof. Subhradip Ghosh, IIT Guwahati, and Dr. N. Padma of Physics group, Bhabha Atomic Research Centre (BARC), Mumbai, under BRNS (Board of Research in Nuclear Science) project, has developed a new soft hybrid material, known as hydrogel, to increase the energy storage performance of supercapacitor devices, stated a press release.

A hydrogel is a porous framework of interconnected materials, in which water remains stably locked within the pores. As a building block of the hydrogel, they have chosen two different kinds of nanosheets, namely graphene and MXene, which store charge via two different mechanisms.

The results of this breakthrough work in MXene based supercapacitor technologies were published in Electrochimica Acta and Carbon recently.
