As advanced energy systems are being developed to meet global energy needs, mechanics has emerged as a key aspect that affects the performance of energy materials and plays a crucial role in their design. For example, thermal stresses and mechanical defects affect the performance and reliability of thermoelectric energy conversion and photovoltaic materials. Intercalation and reaction induced stresses and strains can influence the capacity, cyclic stability, and kinetics of chemical reactions in energy storage devices such as batteries. In particular, the performance of next-generation conversion reaction materials for energy storage is tightly coupled to mechanics. Mechanics of materials issues are universal in all aspects of energy conversion, storage, and harvesting, and play a critical role in the performance of advanced energy materials and systems.

The aim of this symposium is to bring together engineers, scientists, and leading experts in the field; to provide a platform to discuss current research developments; and to promote idea sharing to advance understanding of the mechanics and electrochemistry of advanced energy materials.

Topics addressed in this symposium will include (but are not limited to):

i)    Theoretical studies: DFT, Molecular Dynamics, and continuum models of electro-chemical-mechanical systems

ii)    Experimental studies: Characterization of basic mechanical properties, degradation mechanisms, and measurement of evolution of mechanical properties

iii)    Studies which combine theory and experiments, as to explore how electrochemistry and mechanics phenomena couple together and how they affect the performance of energy systems

iv)    Studies on mechanics-guided material design and optimization and innovative designs for improved performance of energy systems.
