报告摘要:

In this presentation, after an overview of second ion batteries, I will present our most recent research on the synthesis of various promising cathode materials for divalent ions including both magnesium and zinc, with controlled or tuned interlayer distance, bulk defects and surface chemistry to attain desired storage capacity and transport properties. The cathode materials investigated include vanadium oxides, vanadates, manganese oxides, and Figure 1 shows the zinc-ion charge-discharge curves and rate performance of vanadate cathode. In addition, we will discuss the introduction of surface passivation layer on magnesium anode by the formation of an ionic conductive but electronic insulating.
