Critical Grain Size for Microcracking During Lithium Insertion
Abstract
I derived a critical grain size below which microcracking does not occur based on volume changes as a result of Li charging into brittle Li-alloys. The predicted critical grain size is less than the unit cell size for a majority of single-phase materials. This suggests that decreasing the particle and/or grain size is not a practical solution for solving the mechanical instability problem of Li-alloys.
