2-Dimensional Graphene/MoS2 HeteroStructures as AnodE Compartment of SodIum IoN BattEries
The global shift toward renewable energy has made energy storage a key technological challenge. Since solar and wind power are intermittent, storing electricity reliably and affordably is vital for a stable and sustainable energy supply. Lithium-ion batteries (LIBs) currently dominate storage in electric vehicles and electronics, but the rising cost, limited supply, and uneven distribution of lithium highlight the need for alternatives. Sodium-ion batteries (SIBs) offer a promising solution. Sodium is abundant, widely available, and shares many characteristics with lithium, making SIBs attractive for large-scale storage. However, finding efficient and durable anode materials remains a major hurdle. The SEINE project addresses this challenge by developing advanced two-dimensional (2D) materials made from graphene and molybdenum disulfide (MoS2). These materials are assembled into heterostructures—ultra-thin layered systems—that combine the best properties of each component. The project explores how different combinations and modifications, such as doping with nitrogen atoms, affect the electrochemical behavior and stability of the anodes. By understanding these effects in detail, SEINE aims to design anodes that are more efficient, stable, and cost-effective. The project brings together expertise from top European research institutions to investigate these advanced materials using state-of-the-art synthesis techniques, high-resolution microscopy, and electrochemical testing. Its long-term goal is to contribute to the development of next-generation batteries that are not only cheaper and safer but also made from earth-abundant elements—helping Europe lead the way in green energy technologies and support the transition to a low-carbon economy.

Project objective
Lithium-ion batteries have been known as the main solution to the global demand for energy storage devices. However, the rising cost and limited availability of Li have hindered the further development of these batteries. Hence, the research paradigm has shifted to develop earth-abundant elements-based rechargeable batteries among which, sodium-ion batteries (SIBs) show promising potential.The main challenge in developing SIBs is to prepare anode material with high capacity and long cycle life. The low cost, versatile synthesis methods, and ample interlayer distance of MoS2 (MS) have attracted researchers to investigate the possibility of using it as the anode section of SIBs. SEINE aims to develop two-dimensional-heterostructures using derivatives of MS and graphene (Gr). While the presence of single-layer Gr with low defect density beneath MS enhances the electrical conductivity compared to pure MS, the formation of dopants and defects on N-doped MS and N-doped Gr (a) forms active sites for Na+ adsorption, (b) modifies the interlayer interactions, (c) affects the Solid-Electrolyte Interface evolution mechanism, and (d) promotes the stability of the anode. Each of these effects will be investigated in depth using different physical and electrochemical characterization methods.We believe that SEINEs outcomes will pave the way to answer fundamental questions regarding the mechanisms which affect the performance of SIBs and hence to develop cost-effective, durable, and high-capacity batteries. Thanks to the experiences obtained in this fellowship, Navid Solati Eskandar will be trained as a scientist with a broad interdisciplinary perspective and expertise in different electrochemical applications. Different steps and tasks of SEINE will be performed via collaboration between Navid and Prof. C. Laberty-Robert at Sorbonne University, Prof. Sarp Kaya at Ko University, and Prof. Ovidiu Ersen at the University of Strasbourg.
