Nanomechanical Characterization of Battery Materials in a High Purity Environment

Batteries are ubiquitous to our modern life. These batteries, however, begin to degrade in performance with each charge-discharge cycle. This performance degradation is often a result of chemical and mechanical changes at the interfaces. Understanding and controlling these changes are required to further increase energy density, number of charge-discharge cycles, and safety while decreasing cost and weight.

This webinar will focus on nanomechanical (nanoindentation) materials testing that is best performed in a low-oxygen, low-moisture environment.

Measurements of hardness and modulus are presented on current-generation lithium-ion cathodes. The primary focus will be on measurements obtained for solid electrolyte battery components; compressed sulfide powder-based solid electrolytes undergoing densification and intergranular fracture; soft foils of lithium and sodium foils with a strong rate effect; and variation of density in 1/2 cell solid-state lithium batteries. The techniques presented allow researchers to quantify highly localized mechanical degradation, enabling the development and integration of new materials for next-generation batteries.
