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.”

AutoNxt Automation visits campus

Interactive session with industrial inventors

World’s First Electric, Autonomous Tractor

Kaustubh Dhonde, CEO, Swadeep Pillarisetti, Advisor and Board Director, Sachin Gowda, Embedded Engineer, and Aswanth Mulupuri, Intern, Department of Automation of AutoNxt Automation – an innovative Mumbai based startup, visited SRM University AP, Andhra Pradesh for a two-day program as a part of the National Science Day celebration at the campus. The company demonstrated their latest technological marvel, the World’s First Electric, Autonomous Tractor. “A lot of research is conducted globally with multiple companies working on the automation of on-road vehicles. However, off-road vehicles’ automation has hardly been touched upon previously, although there are less variables being controlled environments like farms, industrial plants, etc where it is more feasible a solution”, says Mr. Swadeep who has been advising the company which has brought about a revolutionary breakthrough in the domain of Indian agriculture.

Some of the exceptional features of the Electric Automated Tractor include fully electric drivetrain, low NVH (Noise, Vibration and Harshness) levels, mobile application for interaction with the tractor, live tracking, geo fencing capabilities, battery and system status reports on mobile app, obstacle detection technology and optional automatic hydraulic control of implements. The company is also planning to develop a common charging point that will use free energy sources.

AutoNxt Automation has created its niche by offering cost-effective and energy-efficient solutions to farming problems. Mr. Kaustubh believes “It is important that technology reaches out to the entire farmer class”. He further explains the crises of the Indian agricultural system that can be resolved using the Electric Automated Tractors, “The harvesting timeframe is narrow which increases the demand of skilled labour during this season, exponentially enhancing the cumulative cost of farming. The fully automated tractors embedded with camera identification systems and sensors reduce the operational expenses up to 4 times. Also, the IoT sensors give real-time feedbacks ensuring accuracy in tilling, ploughing, and spraying insecticide.”

The representatives of the company held a demonstrative session with the students and faculty on 26th February 2020, where they introduced the tractor and explained its technological viabilities. An interactive session was also held with the students on the same day. The session enabled the students to identify the practical applications of their acquired theoretical knowledge. The entrepreneurs inspired the students to create an impactful change that will eventually benefit society as a whole. Also, it creates an opportunity for them to be closely associated with people from the industry as well as the research domain. On the following day, a presentation was made to the faculty members of SRM AP to trigger discussions on technologies used by the Electric Automated Tractor. In the end, Mr. Kaustubh and Mr. Swadeep expressed their intent to involve students to work on real-time projects with the company, along with taking assistance from the faculty members to overcome hurdles pertaining to AI/ML technologies. Mr. Swadeep says, “The students will be exposed to real case studies, contribute to the improvement of the country, and in the process earn many accolades”.

Prototypes were awarded in ETHDenver International Hackathon

Innovations of SRM University-AP’s Students were acknowledged and rewarded in ETHDenver, an International Conference organised by Ethereum Foundation. Ethereum Foundation is the largest platform for blockchain technology development. In this conference, they arranged for an US Blockchain Technology Hackathon, the biggest challenge on blockchain technology developments and applications. Approximately 2000 students across the world registered for the conference. Students of SRM-AP presented their innovative ideas with prototypes and secured bounty of total $3000 for their projects called URBANBOWL and SECURENOTE. They were also awarded the Community Prize for being on the Top 5. As a part of Global Scholars Programme supported by Ethereum Foundation, the students represented SRM University-AP in the conference.

URBANBOWL was developed by Koushik Bhargav, Pushyamitra, Srinivas Teja and Rohit, four students of 3rd year, Computer Science and Engineering Department. This project was about making cities self-sustainable by urban farming on rented places. Considering the American societies, where people have unused places like the backyards, the students developed prototype of Urbanbowl, a decentralised urban farming platform where people can lease out empty spaces like backyards or basements. This platform was developed using blockchain technology. Their project also satisfied five UN Sustainable Development Goals (SDG)- End Hunger, Sustainable Cities and Communities, Reduction in Forest Loss and Land Degradation, Climate Action and Sustainable Production Pattern. The students received a bounty of $500 from SKALE and $500 from DAPPHERO for their project.

Securednote  participants praised in ETHDenver

SECURENOTE, the second project from SRM-AP, was also highly praised in the conference. Yoganand and Nikhil, 3rd year students of Electronics and Communication Engineering along with Chaitanya and Abhin, 3rd year students of Computer Science and Engineering were the brains behind the project. They have developed a platform where people’s complaints will not go unnoticed. The present scenario in Indian police station shows that people register their complaints manually, and most of the times, those complaints get lost or no action is taken. Using blockchain technology, students of SRM-AP have developed such a platform where such complaints will be registered and digitised in such a way that cannot be modified later without bringing it into notice of all the concerned authorities. This will make the process more secure as none will be able to alter or modify the complaints without notifying the concerned people. They also have received a bounty of $2000 from DAOSTACK for their project.
