Our paper “Lithium Mechanics: Roles of Strain Rate and Temperature and Implications for Lithium Metal Batteries” is published in Journal of the Electrochemical Society. In this paper we present a comprehensive set of mechanical deformation experiments on bulk lithium, demonstrating strong strain rate and temperature dependence. This is attributed to power-law creep, which we show is the dominant deformation mechanism for Li metal anodes over a wide range of battery-relevant conditions. Examples in solid-state and liquid lithium metal batteries are discussed. [link]
