Solving socioeconomic challenges through advanced energy storage
The ongoing impact of climate change and the energy crisis presents formidable socioeconomic challenges. Developing cutting-edge energy storage technologies is imperative for ensuring a clean and affordable energy supply. While current Li-ion technology has served well, it is reaching its limits in performance and environmental impact. Supported by the Marie Sklodowska-Curie Actions (MSCA) programme, the CiPBAT project will explore novel cathode materials for high-energy reversible magnesium (Mg) and calcium (Ca) ion storage, potentially revolutionising battery technology. It proposes a novel approach using 1D linear coordination polymer-based cathode materials. By synthesising conjugated sulfonamide-based compounds, the project aims to achieve high-voltage operation and cycling stability. Success could revolutionise battery technology, offering sustainable, affordable, and environmentally friendly energy solutions.
The aftermath of climate change & energy crisis are acknowledged as one of the most demanding socioeconomic challenges of modern times. Frontier energy storage technologies are crucial to develop to ensure clean & affordable supply of energy. Current Li-ion technology (LIB) is approaching its limit, whether concerning performance metrics or environmental impact. In turn, rechargeable Mg or Ca-based batteries show great theoretical promises in all these aspects. However, unavailability of suitable high voltage cathode materials with practical power & energy metrics limits their application. In this proposal, we will explore a novel type of 1D linear coordination polymer (CP)-based cathode material for high-energy reversible Mg- & Ca-ion storage (CiPBAT). Our innovative approach is to synthesize anionic CPs in discharged state (containing Mg- or Ca- cation) like a typical LIB inorganic cathode. We will synthesize conjugated sulfonamide-based cathode materials, followed by a consolidated understanding of the electrode reactivity through structure-performance correlation by physicochemical, electrochemical & operando techniques. Final objective here is to construct prototype CiPBAT pouch cells that can operate at high voltage (~2-3 V for Mg & ~3-4 V for Ca) with good cycling stability of atleast 250 cycles. By combining my strong expertise in core electrochemistry with excellent background of host supervisor on organic battery materials and secondment lab on divalent battery chemistry, the project will be effectively implemented. The successful completion of this project will also lead to constructing the first Mg & Ca-metal, but also, anode free prototype cells. This will boost the sustainable all-organic divalent battery research to a new level and replace the need of scarce, expensive & controversial supply of raw materials in current systems. Finally, this fellowship will provide me with great opportunities to achieve professional excellence & research independency. |
