| Abstract Scope |
“Lithium metal” batteries operate via electroplating/stripping of Li metal and promise vast theoretical capacities. However, the primary challenges to practical deployment include the generation of mechanical stresses and strains due to "infinite volume expansion,” as well as non-uniform deposition of lithium metal, which often leads to dendrite formation. With these issues in mind, this talk will discuss recent experimental studies of the mechanical response of lithium during electrodeposition under various electrochemical conditions; it will particularly focus on assessing the sensitivity to lithium electrodeposition to varying applied current densities. The talk will also present results of nanoindentation creep tests on bulk lithium and electroplated lithium to compare their mechanical behavior. Beyond having implications in electrodeposition itself, plating of lithium and the growth of lithium dendrites share similar characteristics; as such, results presented in this talk will have further implications for lithium dendrite growth in solid-state electrolytes. |
