Electrical energy storage is a rapid developing field with significant impact in decarbonising our energy sector. Current energy storage technologies are mainly relied on Li-ion batteries (LIBs), which are facing severe challenges in safety, energy density and price.
Aqueous metal-air batteries use oxygen from the air as one of the battery’s main reactants. They have attracted much attentions for next generation battery technologies, due to remarkably high energy density. Magnesium-air (Mg-air) battery as a type of metal-air batteries, has a high theoretical voltage (3.1 V) and theoretical energy density. However, application of Mg-air batteries is limited due to the challenges of low utilization efficiency of anode and sluggish kinetics of air cathode.
The objective of this research is to develop high performance aqueous magnesium-air batteries. Produce aquesous metal-air battery with selected anode materials, electrolyte and air cathode. Conduct electrochemical measurements and materials characterisation to understand the battery performance.
