Mechanics of Flexible and Wearable Electronic Energy Systems

The role of mechanics in various advanced energy systems is crucial since the device's efficacy mainly depends on the mechanical integrity of the system. For instance, the working of energy storage systems including Lithium-on batteries (LIB) consists of a complex chemo-mechano-electro process. This work will cover how the electrodes of LIBs respond to the diffusion of Li-ions. The diffusion-induced-stresses (DIS) play a critical role in the cyclic life as well as the high energy density of the battery. The extensive FEM analysis revealing fracture conditions, DIS, and volumetric expansion, followed by experimental investigations will be discussed. Our study shows how DIS stresses evolve and what methods can be utilized to mitigate these stresses, which in turn enhances the performance of LIBs. Brief details of current recent research trends i.e., 2D materials-based LIBs will also be discussed.
