| Abstract Scope |
Despite advances in energy storage, the development of new batteries with high energy density, power density, and life cycle remains elusive. Two-dimensional materials (2DM) and their heterostructures are among the most promising energy materials for advanced batteries. This talk addresses two important aspects of 2DM-based batteries – (i) 2DM-based anode materials, and (ii) 2DM as van der Waals (vdW) slippery interface. The conventional anode materials have several problems, such as low gravimetric capacity and high-volume expansion. Our study shows that topologically modified 2DM can be designed for stable high-capacity anode materials for ion batteries. Several electro-chemo-mechanical challenges such as trapping of adatoms at the defect sites, diffusion-induced stress are discussed. The second part of the talk discusses the interface between anode and current collector. Our study reveals the reduction of interfacial stress between the anode and graphene-coated current collector. Experimental findings are in good agreement with our computational results. |
