Abstract: 

Renewable energy technologies and the energy storage technologies for both mobile and stationary applications are of paramount importance to lower the demand on fossil fuels and to mitigate the adverse effects of global warming associated with the excessive usage of fossil fuels. As the worldwide energy generation portfolio involves more renewable energy based technologies, there will be more urgent need for the efficient and cost effective energy storage technologies for both mobile and stationary applications. Moreover, carbon capture and sequestration (CCS) technologies will become more and more widespread as the fight for global warming becomes more fierce. Therefore, in mid future energy storage related research will continue to be a hot topic worldwide. In this seminar, current state of research on materials for energy storage technologies, specifically hydrogen storage and Li-ion batteries, will be discussed.

In this part of this seminar, spillover enhancement in hypercrosslinked polystyrene (HPS), ammonia suppression in LiNH2-MgH2 complex hydride (Li-Mg-N-H) by Ru doped SWCNT, nitrogen rich porous aromatic frameworks and the guidelines for accurate volumetric hydrogen storage measurements will be discussed. Also in-situ atomic force microscopy (AFM) of LiFePO4 cathode to understand the morphological changes (i.e., particle size changes and agglomeration) as well as mechanical degradation of the LiFePO4 cathode by aging will be discussed.
