Summary: Magnesium rechargeable batteries (MRBs) are attracting attention due to their low cost, high safety, and high theoretical volumetric capacity. The use of eutectic and hypereutectic Mg-Sn alloys as anodes for MRBs was explored. The alloys exhibited unique microstructures and the dissolution processes were studied in an all-phenyl-complex (APC) electrolyte. Hypereutectic alloys showed better battery performance due to their superior mechanical properties.

Summary: Magnesium-air battery with a novel Mg64Zn36 alloy anode has achieved a high discharge specific capacity and outstanding efficiency, breaking efficiency records among reported Mg anodes. The high efficiency is attributed to inhibiting hydrogen evolution by Zn alloying, passivating the Mg matrix, and converting intermediate ion Mg+ electrochemically. Uniform discharging products due to the homogeneous microstructure of Mg64Zn36 also contribute to the high efficiency. This design may open a new avenue for the development of Mg-air batteries.

Summary: This study presents a novel design of passivation-free magnesium alloy anode for high-energy-density magnesium/sulfur batteries. By utilizing an alloy with lithium that undergoes a substitution reaction with magnesium ions in the electrolyte, the passivation reaction on the anode is hindered, resulting in improved interfacial reaction kinetics and reduced impedance. The magnesium/sulfur battery with this passivation-free Mg-Li alloy anode achieves an enhanced discharge voltage platform and higher energy density.

Summary: This study focuses on enhancing the antibacterial properties, mechanical properties, and corrosion resistance of Mg-5Zn-0.5Zr-0.7Cu alloy through alloying and thermomechanical processing. The results showed that forging led to significant grain refinement and texture strengthening, resulting in a 1.2 times increase in strength and a 2.3 times reduction in in vitro degradation rate. Both alloys demonstrated complete inhibition of E.Coli bacteria within 32 hours of culture, attributed to the addition of Cu. The non-toxic nature of the alloys was confirmed through cell viability studies, suggesting the potential use of Mg-5Zn-0.5Zr-0.7Cu alloy as internal fracture-fixation material.

Summary: This study investigates the effects of aging treatment on the corrosion resistance and discharge performance of AZ63-1.5 rare earth mischmetals alloy in low-power dissolved oxygen seawater batteries. The study finds that aging treatment leads to a change in crystalline orientation and an increase in Mg phases proportion. Solutionizing and aging also reduce the self-corrosion of the alloys and shift their discharge potentials to more negative values. The favorable corrosion performance is attributed to grain refinement, increased contribution of corrosion-resistant phase, low contribution of layered phase, and formation of dense discharge products.

Summary: This study investigates the effects of electrolyte exposure time on phase composition, biodegradation, and biocompatibility during micro-arc oxidation of the Mg-Ca-Zn alloy. The results show that micro-arc oxidation can form a dense coating with a gradient structure, and the amorphous component of the coating increases with exposure time. The coated Mg-Ca-Zn samples exhibit reduced weight loss in vitro and high biocompatibility in animal experiments.

Summary: This study demonstrates the potential of extrusion-based additive manufacturing (AM) Mg-Zn scaffolds as biodegradable bone-substituting biomaterials. Through pre-alloying of Mg-Zn powder, the corrosion resistance and mechanical properties of the scaffolds were significantly enhanced. The in vitro biodegradation rate and corrosion rate of the Mg-Zn scaffolds were reduced compared to pure Mg scaffolds. The scaffolds also showed favorable cytocompatibility with preosteoblast cells.
