title = "Micro/Macro-Scale Modeling for Battery Fast Charge Applications",
abstract = "In conjunction with experiments at Argonne and Idaho National Laboratories, the National Renewable Energy Laboratory is applying physics-based electrochemical models at several length-scales to understand limitations and guide design of future battery electrodes for extreme fast charge of electric vehicles. Macro-homogeneous models show that today's battery technologies must use thin electrodes to avoid electrolyte depletion and lithium plating at a 6C (10-minute) charge rate. This compromises cost and energy density however. Goals are provided for next generation electrode tortuosity and electrolyte transport requirements to achieve 6C charge in a thick electrode system. Microstructure models provide quantitative understanding of tortuosity for several graphite electrodes and further predict heterogeneous utilization of the electrodes due to their morphology.",
