Abstract

Most lithium ion battery electrodes experience large volume expansion and contraction during lithiation and delithiation, respectively. Electrode failure, in the form of fracture and decrepitation, can occur as a result of repeated volume changes. In this paper, we provide an overview of our recent work on modeling the evolution of concentration, stress, and strain energy within a spherical- or cylindrical-electrode element under various charging-discharging conditions. Based on the analytic results, we propose tensile stress and strain energy based criteria for the initiation and propagation of cracks within the electrodes. We will also discuss "size effects" on stresses and fracture of electrodes. These results may help guide the development of new materials for lithium ion batteries with enhanced durability and performance.
