報告摘要：

Lithium-ion batteries (LIBs) have been extensively applied in many fields such as consumer electronics, electric vehicles and renewable energy storage due to high energy density and long cycle life. However, next-generation high-capacity LIBs are accompanied by strong electro-chemomechanical coupling behaviors, and mechanical degradation is one of the main limitations for the commercial application of the high-capacity LIBs. For the high-capacity LIBs,in this presentation, we focus on the understanding of deformation and failure behaviors from the levels of electrode particle and electrode around the electrochemo-mechanical coupling mechanisms of electrode materials, and the design of electrode structures. The aims of these studies are to achieve the durability, capacity, and safety of LIBs.
