    Abstract:

    Nanomaterials have dominated research in engineering and the physical sciences for almost twenty-years. Yet, their applications are still not at the expected capacity. A most well known example is the case of next generation rechargeable batteries that employ high capacity anodes. Metal-based anodes allow for capacities for Li-ion and Na-ion batteries of 990-4000 mAh/g, which are 3-10 times higher than current Li-ion cells. However, they cannot be commercialized due to the mechanical instabilities, such as severe fracture, that arise during the initial charge-discharge process of the battery. To overcome this limiting factor the most effective approach is to coat the metal nanoparticles with a matrix, as the resulting interfaces can increase the mechanical stability and allow for a significantly longer battery lifetime. It is necessary, therefore, to account for such interface terms in the constitutive equations to develop design criteria. As a result new nanostructured Si and Sn anodes that can withstand fracture can be fabricated. The talk will elaborate on the most promising candidates that are expected to be commercialized within the next five years. In closing the new perspectives in energy storage that such anodes can provide will be elaborated.
