Replacing Cobalt with Nickel in Lithium-ion batteries

Dr. Sujith Kalluri, Assistant Professor of Electronics and Communication Engineering, published a paper on “Building High-Rate Nickel-Rich Cathodes by Self organisation of Structurally Stable Macrovoid” in a highly reputed journal, “Advanced Science” having Impact Factor of 15.8. During his association with Samsung- UNIST Battery R&D Centre at Ulsan National Institute of Science and Technology (UNIST) South Korea, he began researching on the alternate battery cathodes for high-rate lithium-ion batteries, and proceeded the study at SRM University AP, Andhra Pradesh.

Cathode is one of the key components of batteries used in portable smart devices (mobile phones). Presently, batteries comprise of Lithium Cobalt Oxide as a cathode. Dr. Kalluri’s research focuses on the fast mobility of the lithium-ions present inside the battery with respect to the applied electricity. In his path-breaking study, he designed a new cathode for batteries, which is Lithium Nickel-rich transition metal oxide. He explains the supremacy of his designing Nickel-rich cathode, “When we did thorough electro-chemical and electrical studies, the lithium-ion batteries infused with nickel-rich cathode exhibited higher performance in terms of high current operations and elevated temperatures. Also, the Nickel-rich based lithium-ion batteries are a cost-effective substitute as the major portion of Cobalt is replaced with Nickel, a cheaper metal. These batteries can be employed in portable electronic devices and in larger scale, can be a promising candidate for e-mobility appliances.”

The research of Dr. Kalluri also aims at improving the “high current rate operation” which will ensure fast charging of portable devices and electric vehicles. When asked regarding his future research plans, he says “At SRM AP, we are establishing SRM – Amara Raja Centre for Energy Storage Devices in association with Amara Raja Batteries Limited. In this centre, we are planning to further optimize the lithium-ion battery technology, and also we will look beyond and try to implement sodium-ion battery technology for societal demands.”

25th -27th August, 2020: Dr. A Vadivel, Associate Professor – Department of Computer Science and Engineering, will be organising a special session titled “Deep Video Analytics and Big Visual Data: Computational Models, Algorithms and Applications” at the 27th INTERNATIONAL CONFERENCE ON SYSTEMS ENGINEERING, Las Vegas, USA.

Dr. Gunasekaran welcomed all the guests and addressed the audience. He introduced the university by recalling its infrastructural dominance, mentioning the eminent faculty, and discussing the collaborations with the University of California, Berkeley where students are sent for semester abroad programs. He also emphasized on the exposure offered to the students through international and national internships. “Our university encourages the young researchers through UROP where the students individually or in a group take up mini-projects under the guidance of our faculty. “Our faculty has published more than 120 journals in the last one year, along with 23 sponsored projects and 64 proposals that await funds from the agencies. SRM University AP, Andhra Pradesh is also collaborating with Indian Railways to build Hydrogen Trains, and Amara Raja Group on Energy Storage”, Dr. Gunasekaran pronounces. He also expresses his gratitude to the distinguished guests and assures to extend extensive support from the university’s end.

The Asian Consortium on Computational Materials Science (ACCMS) was set up in 2000 to promote research and development activities in computational materials in Asian countries. Prof. Yoshiyuki Kawazoe says “Computational materials was not a coined term in Japan when we started off this organization 20 years back. We merely had 7-8 participating nations who met on virtual platforms regularly or at conferences once in a while. In order to optimally utilize our resources and manpower, it is widely felt that we should have a ‘real’ organization to steer young researchers towards computational research. It is envisaged that the conduct of the International Conference on Material Genome at SRM University AP, Andhra Pradesh will lay the foundation for an active center of ACCMS on campus.”

He further addresses that the purpose of ACCMS is to solve large probabilistic problems through Quantum Mechanics based calculations followed by Machine Learning (QM/ML). “We are aiming at developing language and characters prior to the western nations and secure a superior position for Asian countries”. Few themes to be covered in this chapter of ACCMS conference includes “Machine Learning for materials”, “High-throughput Computation”, “Polar Magnetic Materials”, “Thermoelectric Materials”, etc.

Fracmeet conferences are being organized for over a decade to focus on an aspect of Material Science – “Mechanical Properties of Complex Materials.” The multidisciplinary collaborative meetings of this organization welcome scholars from Chemistry, Physics, and Engineering domains, along with people from the industry. Prior to this, the annual conferences and meetings of Fracmeet were held at IMSc., Chennai, where Fracmeet was initiated. For the first time, SRM University AP, Andhra Pradesh, having exceptional infrastructure and facilities, is hosting this conference in collaboration with IMSc. This year, Fracmeet is aiming at discussing “Micromechanics of failure in disordered material” in this conference.
