Research Projects

The proposal outlines the novel approaches that we plan to execute in developing high performance cathode materials for Na-ion batteries. The proposed research work explores various strategies for the development of Na3V2(PO4)3 -and Na3Ni2SbO6 -based high voltage cathode materials, with varying morphologies, and modified structures, by using solid-state and sol-gel methods. The electrode materials will be characterized for their structural, morphological and electrochemical properties. Further, growth parameters and doping will be optimized to achieve enhanced electrochemical performance. It is envisaged that an in-depth understanding of the electrochemical reaction mechanisms in the optimized cathodes will be achieved with a focus on diffusion studies along with ex-situ and post-mortem analysis. In pursuit of practical implementation of Na-ion batteries, our aim to explore full cell device fabrication with optimized hard carbon based anode materials with optimal electrode mass balancing would open up an exciting new pathway for efficient energy storage devices. The proposal further explores the possibility of interface modification of the developed cathode materials with certain sodium based solid-electrolytes for their use in all-solid-state sodium ion batteries. Finally, a proof-of-concept demonstration of the fabricated device will be attempted.
