Innovation by BHU researchers revolutionises sodium-ion battery

  • | Thursday | 28th September, 2023

Varanasi: In a groundbreaking innovation that has the potential to transform the energy storage landscape, a team of researchers from the department of Physics, Institute of Science, Banaras Hindu University, has successfully synthesised cutting-edge cathode materials designed to charge sodium ion batteries. These materials promise an enhanced capacity and prolonged battery life. A prototype battery pack featuring these innovative cathode materials has already been put to test in an E-bicycle.Traditional lithium-ion batteries have long been the go-to choice for energy storage, but sodium ion batteries offer a compelling alternative. Unlike lithium, sodium is abundant and inexpensive, making it an eco-friendly choice. Moreover, sodium ion batteries possess chemistry similar to lithium, adding to their appeal. However, challenges like safety, stability, and energy density have held back their widespread adoption. BHU scientists, led by Prof Rajendra Kumar Singh, have addressed these challenges. Other members of the team included Raghvendra Mishra, Rupesh Kumar Tiwari, Anupam Patel, Anurag Tiwari, Vikash, Shitanshu and Samriddhi. The team not only developed sodium nickel manganese cobalt oxide (Na-NMC) and sodium nickel manganese iron oxide (NFM) cathode materials but also designed novel sodium super ionic conducting solid-state electrolytes tailored specifically for sodium ion batteries. This achievement was made possible through support from the Ministry of Education and the Science and Engineering Research Board (SERB) supported IMPRINT II project. These findings have been featured in reputed, high-impact international journals like the Journal of Power Sources, ACS Applied Materials and Interfaces, Energy & Fuels, Journal of Energy Storage, and Chemical Engineering Journal.The breakthrough lies in the innovative sodium super ionic conducting solid-state electrolytes, which efficiently transport sodium ions within the battery enhancing safety, stability, and energy density. To complement this achievement, an industry collaborator has developed a compatible battery management system (BMS) and a suitable charger.Sodium ion batteries hold the key to providing a cost-effective and sustainable energy storage solution. This breakthrough has the potential to accelerate the adoption of electric vehicles, renewable energy systems, and overall energy sustainability, said Prof Singh. According to him, the research journey involved synthesizing solid electrolytes, optimizing the composition of NaNMC and NFM cathode materials, and fabricating cylindrical cells. A prototype battery pack, consisting of sodium ion cylindrical cells (42 V, 6Ah pack), was tested in an E-bicycle, achieving an impressive 54 km distance on a single charge with a maximum speed of 30 km/hr.Prof Singh said that as the world places an increasingly urgent emphasis on sustainability and cost-effectiveness, these advancements by the research team could serve as a significant boost to the Make in India initiative and facilitate the commercialization of sodium ion batteries. With readily available raw materials, the potential for cost reduction, and increased energy density, sodium ion batteries have the potential to reshape our energy storage landscape, propelling us toward a cleaner and more sustainable world.
