Metal-organic frameworks (MOFs)-based nanomaterials have great potential in the field of electrochemical energy storage due to their abundant pore size, high specific surface area, controllable structure and porosity, and homogeneous metal center. MOFs complexes and derivatives not only inherit the original morphology characteristics of MOFs but also provide excellent electrochemical performance. Batteries operating in aqueous electrolytes are cheaper, safer, and have higher ionic conductivity than those operating in conventional organic electrolytes.

Lithium argyrodites LiPS ( = Cl, Br, I) are a promising class of solid-state electrolytes with the potential to achieve high conductivities (>10 mS·cm) necessary for use in solid-state batteries. Previous research has shown that structural factors, in particular, site disorder between the sulfide and halide anions, can impact the ionic conductivity of lithium argyrodites. One current hypothesis for this correlation between anion site disorder and ionic transport is a connection to the lithium-ion substructure.

Defect chemistry is the classical approach to evaluate point-defect concentrations in solids depending on the chemical activity of the ( - 1) of constituents by evaluating the mass action laws of a number of defect reactions conserving species, lattice sites, and charge. In an alternative approach, formation energies of individual defects can be calculated to determine the dependence on the Fermi level and on the chemical potentials of the reservoirs. This contribution provides the quantitative relationship between the two approaches, offering the opportunity to compare calculated defect formation energies with experimentally determined quantities.

In recent years, halide perovskite materials have been extensively studied by researchers due to their excellent optoelectronic characteristics. Unlike traditional semiconductors, halide perovskites possess unique ionic crystal structures, which makes it easier to perform facile composition engineering to tailor their physical and chemical properties. Ion exchange is a popular post-treatment strategy to achieve composition engineering in perovskites, and various ion exchange processes have been used to modify the structural and functional features of prefabricated perovskites to meet the requirements of desired applications.

The integration of two-dimensional (2D) nanomaterials into polymer-based packaging presents a promising avenue for sustainable, high-performance materials. This perspective explores the roles of colloidal interactions in the assembly of 2D materials into thin films for packaging applications. We begin by analyzing the types of colloidal forces present in 2D nanomaterials and their impact on dispersion and stability.
