title = "Understanding Impact of Local Heterogeneities During Fast Charge",
abstract = "Reducing battery charging time to 10 minutes would improve the market acceptance and utility of electric vehicles. Such a fast charge rate is difficult to achieve in energy-dense thick battery electrodes, however. In particular, fast charge can drive a lithium plating side reaction that is unsafe and degrades battery capacity. The onset of the lithium plating side reaction is accelerated due to non-uniformities, or heterogeneities that exist within the negative electrode active material particles, within the coating, and at larger battery length scales as well. This presentation summarizes fiscal year 2018-2019 work by NREL, Argonne National Laboratory and Purdue University in the atomistic modeling of Li transport within graphite and continuum modeling of electrochemical heterogeneities that cause early lithium plating onset. non-uniformities, or heterogeneities that exist within the negative electrode active material particles, within the coating, and at larger battery length scales as well.
