Symposium Technical Description
As advanced energy systems with enhanced conversion efficiencies, improved storage capacities and better reliabilities are being developed to meet the global energy needs of the world’s growing population, mechanics has emerged as one of the key factors that affect the performance of energy materials. In thermoelectric energy conversion to harvest sunlight and recover waste heats, thermal stress is a big concern for reliabilities, and the efficiency and reliability of photovoltaic materials are similarly affected by both strain and the presence of mechanical defects. In electric energy storage, the capacity and cyclic stability of lithium-ion batteries are often limited by stress and strain induced during ion intercalation and extraction, despite much higher capacity promised by thermodynamics, and mechanical deformation has been found to be a key factor that directly impacts the functionality of capacitors including the so-called quantum nanocapacitance. The importance of mechanical properties of materials for renewable energies, such as wind and tide energies, is also widely recognized, and the very nature of vibration energy harvesting is mechanical. It is evident that mechanical issues are universal in all aspects of energy conversion, storage, and harvesting, and mechanics plays a critical role in the performances of advanced energy materials and systems.
This symposium is intended to bring together experts from materials sciences, mechanics, chemistry and engineering communities interested in energy conversion, storage, and harvesting to review the current state of the art and formulate the outstanding research needs and grand challenges in mechanics of advanced energy materials. Interdisciplinary topics will be connected by invited talks in order to accelerate the fundamental understanding of these materials toward applications. The topic of the symposium includes all mechanics-related problems of materials in energy storage and conversion, including but not limited to batteries, fuel cells, photovoltaics, catalysis, power electronics, etc. Potential topics include:
