Summary: To improve the energy density of lithium-ion batteries, researchers have explored alternative alloy-based anode materials to replace graphite. However, these alloys face challenges due to volume expansion, leading to poor electrochemical performance. To overcome this, various strategies including nanostructuring and introducing conductive phases have been investigated. In this study, a pomegranate-like NiSb/C composite was fabricated and showed stable reversible capacity and rate performance. The performance mechanisms were analyzed using electrochemical impedance spectroscopy and distribution of relaxation times analysis.

Summary: This article presents a method to enhance the moisture resistance of fragile metal-organic frameworks (MOFs) by constructing a customized hydrophobic porous shell, NTU-COF, on MOF-5 using the Plug-Socket Anchoring strategy. It was found that the pore structure of MOF-5 was well preserved and could achieve complete CO2/N-2 separation even under humid conditions. Atomic resolution inspection of the interface between MOF-5 and NTU-COF revealed insights into the assembly mechanism of the core-shell structure.

Summary: The assembly of 3D structured materials from 2D units allows for the construction of thick and dense electrodes, which are highly desirable for practical energy-storage devices. The use of MXene, a 2D transitional metal carbide, shows promise in this field due to its solution-based assembly capabilities and high density. However, the lack of porous ion-transport paths poses a significant challenge in achieving high areal capacitance electrodes. In this study, a gelation-densification process initiated by hydroiodide acids (HI) is proposed, where the protons break the electrostatic balance of MXene nanosheets to trigger gelation, while HI serves as a spacer to prevent restacking of nanosheets during capillary shrinkage. The controlled evaporation of reductive HI results in a shrinking yet porous network for ion transport, leading to monoliths with a high density of 2.74 g cm(-3) and an unprecedented areal capacitance of 18.6 F cm(-2).

Summary: In this study, molecular dynamics and grand canonical Monte Carlo simulations were used to investigate the adsorption and energy storage properties of R32, R134a, and R1234yf in MOF-5 and MOF-177. The results showed that smaller molecular-sized working fluids were easier to absorb and desorb in the MOF structures. Additionally, MOFs with larger specific surface areas and pore sizes could absorb more organic working fluids, resulting in greater enhancement of energy storage.
