Summary: Aluminum-ion batteries (AIBs) are a promising candidate for large-scale energy storage due to their abundant reserves, low cost, good safety, and high theoretical capacity. However, AIBs with inorganic positive electrodes still face challenges such as slow kinetics and structural collapse. In this study, a novel p-type poly(vinylbenzyl-N-phenoxazine) (PVBPX) positive electrode is proposed for AIBs. PVBPX demonstrates a high capacity and an amazing ultra-long lifetime of 50000 cycles due to its dual active sites, expanded pi-conjugated construction, insolubility, and anionic redox chemistry without bond rearrangement. The charge storage mechanism involves the reversible coordination/dissociation of AlCl4- ions with the N and O sites in PVBPX.

Summary: In this study, the interaction mechanism between bismuth (Bi) and alkali metal ions (Li+, Na+ and K+) in aqueous alkali-metal ion batteries (ARABs) was investigated using various experimental and theoretical methods. It was found that Bi exhibited high specific capacity for Na+ and K+ storage, but lower capacity for Li+ storage. The irreversibility of Li+ dealloying from Bi matrix due to large adsorption energy resulted in poor rate performance and cycling stability. The large volume expansion caused by the largest radius of K+ contributed to the poor cycling stability for K+ storage. Bi showed superior performance for Na+ storage due to the appropriate interaction strength between Bi and Na+.

Summary: A recent theoretical study has found that a two-dimensional CuCl3 monolayer behaves as a ferromagnetic semiconductor. Using density functional theory, the researchers investigated the geometrical structure, magnetic, and electronic properties of the CuCl3 monolayer under biaxial strain. It was discovered that the monolayer exhibits ferromagnetic ordering at its ground state and the Curie temperature increases with increasing biaxial strain, reaching about 100 K at 10% tensile strain. However, a transition from ferromagnetic to antiferromagnetic state occurs under compressive strain of about 6.8%. The results of this study provide insights into the tunable magnetic and electronic properties of the CuCl3 monolayer, which are important for the design of spintronic devices based on ferromagnetic semiconductors.
