Mechanical Behavior of Silicon as Anode Material for Lithium-ion Batteries Chon, Michael J creator 2015 xii, 101 p. born digital Thesis (Ph.D. -- Brown University (2015) Guduru, Pradeep Director Chason, Eric Reader Franck, Christian Reader Sheldon, Brian Reader Brown University. ENGINEERING: Mechanics of Solids sponsor theses Developing high energy density battery systems has emerged as a major challenge in recent years. Silicon is considered to be a promising anode material for future lithium ion batteries that can increase the energy density by as much as 30%. Since silicon undergoes large compositional strains during charge-discharge cycling, managing the stress and deformation fields in it is the central challenge in designing silicon-based electrodes. This work presents experimental efforts to quantify the mechanical properties of lithiated silicon and the coupling between stress and electrochemical performance of the material.
