Ameliorating strength-ductility efficiency of graphene nanoplatelet-reinforced aluminum composites via deformation-driven metallurgy

Yuming Xie et al.

Summary: 1.5 wt% graphene nanoplatelet-reinforced aluminum matrix composites were prepared using deformation-driven metallurgy to enhance the strength-ductility efficiency. The study focused on the strengthening-toughening behaviors related to the dispersion of graphene nanoplatelets, interfacial bonding, and grain refinement. Severe plastic deformation and dynamic recrystallization resulted in the uniform dispersion of graphene nanoplatelets and ultra-fine microstructures. The composites showed high-efficiency interfacial bonding and achieved self-compensating spatial continuity through the automatic flow of Al2O3 nanodots.

Aluminum-air batteries: A review of alloys, electrolytes and design

Robert Buckingham et al.

Summary: Research on high theoretical energy density metal battery anode materials, such as aluminum in Al-air batteries, has been ongoing for several decades. Despite the attractive properties of aluminum such as light weight and low cost, commercialization has been impeded by challenges such as aluminum hydroxide surface barrier formation, high corrosion rate, and self-discharge susceptibility. Many studies have explored the use of alloying elements to address these issues in aqueous electrolytes.
