Abstract Scope |
With an increasing demand for higher energy and power density batteries, the coupled electrochemical-mechanical degradation of battery materials (e.g., electrode and solid electrolyte) becomes a more pressing problem. An improved understanding of the mechanical behavior, which often evolves with the state-of-charge and cycle number, is therefore necessary for improving the performance and durability of batteries. In this presentation, I will provide several examples of using the Oliver-Pharr method and the work of indentation methods to measure the mechanical behavior of battery materials, including silicon/polymer porous composite electrodes, lithium metal electrodes, and ceramic materials for the positive electrode and solid-state electrolyte. Indentation-based methods may also be used to investigate the coupled electrochemical-mechanical behavior of a wide range of materials for making better batteries. |
