Hyderabad University and TIFR to Develop Electrode Materials for Sodium-ion Batteries

New Delhi: The University of Hyderabad (UoH) has embarked on a collaborative venture with the Tata Institute of Fundamental Research (TIFR) aimed at developing cutting-edge electrode materials for sodium-ion batteries. 

The collaboration between Hyderabad University and TIFR is a significant stride forward in this domain, bringing together the combined expertise of researchers and scientists from both institutions.

Arya Sohan, a PhD scholar, and Pratap Kollu, a faculty member at the Centre for Advanced Studies in Electronics Science and Technology (CASEST), School of Physics, researched to develop a reduced graphene oxide composite using tin antimony alloy, aimed at facilitating rapid charging for sodium-ion batteries. 

The entirety of this research endeavor was funded by a project grant from the Institute of Eminence at Hyderabad University.

Use of Sodium-ion Batteries

The popularity of sodium-ion batteries is increasing in the energy storage and electric mobility sectors. These energy sources offer improved energy efficiency, rapid charging capabilities, resilience in extreme temperatures, and safeguard against overheating or thermal runaway issues. 

Unlike commonly used batteries dependent on lithium, cobalt, copper, or nickel, which could emit environmentally harmful gases in fire situations, these batteries pose fewer hazards. Moreover, they demonstrate great versatility, catering to a diverse array of applications.

Sodium-ion batteries stand out due to their exceptional tolerance to elevated temperatures and humidity, enhancing their attractiveness. However, a significant drawback of sodium batteries lies in their energy density, indicating the stored energy per volume of the battery. When compared to lithium-ion batteries, sodium batteries exhibit a relatively lower density, ranging from 140 Wh/kg to 160 Wh/kg.
