F20MRS Meeting: Rechargeable Aluminum Batteries Based on 2D Transition Metal Carbide (MXene) Cathodes
The great shift of the energy industry to renewable and sustainable energy resources has attracted a lot of attention to the battery industry. The fast-growing market of EVs is expected to soon be comparable to gas-powered vehicles with the help of new environmental policies and government regulations. But what is the bottle-neck in developing Li-ion batteries?
The safety concerns, limited resources, and high cost of Li-batteries alert the industry to look for alternatives. Aluminum has been introduced as a substitute to replace Li in battery technology. Rechargeable aluminum batteries with aluminum metal anode are considered as one of the most promising alternative energy storage systems to current Li-ion batteries. Aluminum is the most abundant metal in Earthís crust, and it can potentially offer three-electron redox reactions resulting in the highest theoretical volumetric capacity of 8040 mAh cm-3 among all metals.
Dr. VahidMohammadi and his co-workers at Auburn University developed novel rechargeable aluminum batteries using two-dimensional (2D) V2CTx MXene as an intercalation-type cathode that has shown exceptional capacities and rate-capabilities. They show valuable insights about the possible reasons for the capacity loss, thermodynamics, and kinetics of Al3+ intercalation into V2CTx MXene cathode.
Dr. VahidMohammadi further talks about how designing new electrode architectures and modifying electrolyte composition, different 2D MXenes can deliver stable cyclic performance in the aluminum battery system.
