Published: Jan. 31, 2022

Aqueous aluminum batteries are promising post-lithium battery technologies for large-scale energy storage applications because of the raw materials abundance, low costs, safety and high theoretical capacity. However, their development is hindered by unsatisfactory electrochemical behaviour Al metal electrode due to presence an oxide layer hydrogen side reaction. To circumvent these issues, we report aluminum-copper alloy lamellar heterostructures as anode active materials. These alloys improve Al-ion reversibility (e.g., achieving dendrite-free deposition during stripping/plating cycles) using periodic galvanic couplings alternating anodic α-aluminum cathodic intermetallic Al2Cu nanometric lamellas. In symmetric cell configuration with a oxygen concentration (i.e., 0.13 mg L-1) aqueous electrolyte solution, lamella-nanostructured eutectic Al82Cu18 allows 2000 h overpotential lower than ±53 mV. When tested in combination AlxMnO2 cathode material, full delivers specific ~670 Wh kg-1 at 100 mA g-1 initial discharge capacity ~400 mAh 500 retention 83% after 400 cycles.
