Understanding the Mechanical Behaviors of Lithium-Based Battery Anodes─Silicon and Lithium Metal


Abstract This dissertation will investigate two of the most promising high-capacity anode

materials for lithium-based batteries: silicon (Si) and metal lithium (Li). It will focus on

studying the mechanical behaviors of the two materials during charge and discharge and

understanding how these mechanical behaviors may affect their electrochemical

performance.

In the first part, amorphous Si anode will be studied. Despite many existing studies

on silicon (Si) anodes for lithium ion batteries (LIBs), many essential questions still exist

on compound formation, composition, and properties. Here it is shown that some

previously accepted findings do not truthfully reflect the actual lithiation mechanisms in

realistic battery configuratio... (more)
