Abstract
Lithium ion batteries have achieved pervasive applications in many aspects in current technologies and played an indispensable role in our mobile life. Many active research efforts on innovative materials and device architecture are certainly to advance the lithium ion battery further towards higher energy and power density as well as long cycling life. However, the further spread applications of lithium ion batteries are humbled by the limited resources and consequent rising prices of lithium and cobalt metals; search for new battery materials and device design becomes imperative and has attracted increasing attention in the materials and battery communities. 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 layer.
