Rechargeable batteries play a critical role in transmitting and distributing electrical energy. Commercial Li-ion battery (LIB) based on intercalation chemistry are approaching its performance limits in terms of energy density 100-265Wh/kg. LIBs are also facing severe challenges in safety, energy density and price. Magnesium rechargeable battery (MRB) is one of the most promising post-lithium ion battery system due to its low cost and high volumetric capacity. However, a passivating layer of oxides/hydroxides forms and remains on the surface of magnesium anode, which affects electrochemical charge and discharge properties.
This exploratory research projects aims to develop novel anode materials for magnesium rechargeable batteries. New alloys will be designed and fabricated as anodes for MRBs. Assemble MRB cells using the newly developed electrode materials, test cell performance, and conduct failure analysis of batteries. Conduct materials characterization and electrochemical measurements for understanding the battery charge/discharge reaction mechanisms.
