Development of a negative electrode material for sodium-ion battery
My research focuses on converting agricultural waste, plant residues, and petroleum-derived byproducts into high-performance hard carbon for sodium-ion battery anodes. Using both conventional tube-furnace pyrolysis and microwave-assisted heating, I engineer hard carbons with optimised pore structures, defect levels, and macrotextures. These materials are analysed through structural and electrochemical characterisation to understand Na⁺ storage behaviour, efficiency, and cycling stability. The work aims to develop sustainable, scalable hard carbon anodes while valorising low-cost biomass resources for next- generation sodium-ion energy-storage systems.

Modified hard carbon from natural resources as negative electrode for the Na ion Battery.
My work focuses on synthesizing hard carbon from various biowaste sources such as pistachio shells, Pigeon pea, and cotton shells. These natural precursors are converted into carbon through controlled thermal treatment and then optimized for use as anode materials in sodium-ion batteries. The electrochemical behaviour of the produced hard carbons—including capacity, voltage profiles, and cycling stability—is thoroughly analysed to understand their sodium storage mechanisms. This research highlights how low-cost biowaste can be transformed into efficient, sustainable materials for next-generation energy-storage systems.

Recycled Mn-based NMC and Fe based Positive electrode
In my research work, recycled Mn was employed as a sustainable precursor to synthesize high-performance NMC cathode material. To further enhance electrochemical behaviour, the NMC particles were surface modified with a thin Al₂O₃ coating using a simple and low-cost deposition technique. As a result, the modified NMC exhibits excellent cyclic stability with significantly reduced capacity fading over extended charge–discharge cycles. Overall, the combination of recycled Mn utilization and cost-effective Al₂O₃ coating provides an environmentally friendly and economically attractive route to producing durable, high-performance NMC cathode materials suitable for next-generation Li-ion batteries.
