| Title: Strong Electro-Chemo-Mechanical Coupling in High-Capacity Electrode Materials | |
| Abstract: The growing demand for low-cost, high-performance rechargeable battery techniques for portable electronics, hybrid electric vehicles, and large-scale energy storage has stimulated the relentless search for new electrode materials. The successful development and application of such newly identified materials necessitate a fundamental understanding of the electrochemical and mechanical properties of the materials, as well as the intrinsic electro-chemo-mechanical coupling mechanisms in these materials. In this talk, I will present a combined experimental and computational investigation of deformation and failure in high-capacity electrode materials such as silicon, germanium, carbon nanotube, and graphene for their use in advanced rechargeable batteries. The strong coupling between electrochemical charging/discharging kinetics and mechanical stress in these high-capacity electrode materials will be uncovered, which will shed light on the design of new generation failure-resistant electrodes. | |
