Batteries fundamental considerations in search for better intercalation electrodes for lithium-ion

讲座内容：Lithium ion batteries are playing indispensible role in our modern life full of portable electronics and in constant move. However, the advancement of lithium ion batteries has lagged way behind electronics, in spite of extensive research efforts across research venues and industries. In this presentation,Prof. Caowill first present an overview what to be considered for an effective electrodes for lithium ion batteries and then present some of their research results to illustrate how the impacts of defects such as dopants and vacancies, particularly the surface defects, nanostructures, and low crystallinity or amorphous nature of electreodes on the lithium-ion intercalation capacity and voltage, as well as energy efficiency when such materials are used as electrodes in lithium ion batteries.
