The research conducted by faculty at IIT Gandhinagar has been groundbreaking and has contributed significantly to advancing various fields, including engineering, science, social sciences, and humanities. The faculty members at IITGN are renowned experts in their respective fields. Their research has not only resulted in the development of cutting-edge technologies but has also contributed to the growth of knowledge and understanding in their fields. The Institute has been committed to fostering a culture of research excellence and innovation, and its faculty members have been at the forefront of several path-breaking initiatives.
A team of researchers from IIT Gandhinagar and Japan Advanced Institute of Science and Technology (JAIST) invented a material for anode that enables fast charging of a battery and facilitates its long life. According to the team, the new two-dimensional (2D) anode material was developed using nanosheets derived from titanium diboride (TiB2), a material that resembles a multi-stacked sandwich where metal atoms are present in between layers of boron.
"What makes this work especially useful is the fact that the method to synthesise TiB2 nanosheets is inherently scalable. It only requires mixing the TiB2 particles in an aqueous solution of dilute hydrogen peroxide and allowing it to recrystallise. For any nanomaterial to translate into a tangible technology, scalability is the limiting factor.
"Our method to synthesise these TiB2 nanosheets only requires stirring and no sophisticated equipment, making it highly adoptable," said Kabeer Jasuja, Dr Dinesh O. Shah chair associate professor of chemical engineering at IITGN.
The research teams at IITGN and JAIST aimed to develop a material for an anode that not only enables fast charging of a battery but also facilitates its long life.
"This transformational research innovation has rich potential for translation from the laboratory to a real-life application. Currently, graphite and lithium titanate are among the most widely used anode materials in the commercially available lithium-ion batteries (LIBs) that power laptops, mobile phones and electric vehicles. LIBs with graphite anode, which is extremely energy dense, can power an electric vehicle for hundreds of kilometres in one charge cycle," Jasuja said.
"We hope continuous research will contribute to the convenience of EV users, lesser air pollution on the road, especially in cities, and a less stressful, mobile life, which will enhance the productivity of the society," said Noriyoshi Matsumi, professor of materials chemistry at the JAIST.
