Abstract:

Carbon materials have played an essential role in the development of lithium-ion batteries enabling transformative technologies including portable electronics, remote sensors, flying cars and electric vehicles. To meet the growing demand of the energy storage market, next generation batteries must provide dramatically increased capacity and cycling life, operate reliably, fast and safe, at reduced size and weight. Carbon nanomaterials hold great potential in offering a viable solution to these challenges. This talk will discuss current trends in the design of graphene and carbon nanotubes for batteries with high energy and power densities with extended cycling stability. Engineering porous graphene structures with low tortuosity for fast ion transport and chemical modification of the graphene surfaces for increased lithiophilicity are industrially scalable strategies to increase capacity, improve cycle life while simultaneously enhance rate capability and eliminate dendrite formation in batteries.
