Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. It is one of the main bonds along with Covalent bond and Metallic bonding. Ions are atoms that have either gained or lost one or more electrons. Ions that have gained an electron are negatively charged. They are anions. Ions that have lost an electron are positively charged. They are cations. This transfer of electrons is known as electrovalence in contrast to covalence. In the simplest case, the cation is a metal atom and the anion is a nonmetal atom, but these ions can be of a more complex nature, e.g. molecular ions like NH⁺₄ or SO²⁻₄. In simpler words, an ionic bond is the transfer of electrons from a metal to a non-metal in order to obtain a full valence shell for both atoms.
An Al-doped two-dimensional MnO2 adsorption structure for SO2 immobilization and its application
The application discloses an Al-doped two-dimensional MnO2 adsorption structure for SO2 immobilized adsorption and application thereof. The Al-doped two-dimensional MnO2 adsorption structure for SO2 immobilized adsorption comprises a two-dimensional MnO2 monolayer as a substrate, and Al modified atoms on H sites on the surface of the substrate, wherein the doping concentration of the Al modified atoms is 2% to 4%. A stable Al-O interaction interface is formed between the Al modified atoms and O atoms in SO2 molecules, so that a strong chemical adsorption interface dominated by ionic bond interaction is formed between SO2 and the adsorption structure; in a preferred configuration, the adsorption energy of the adsorption structure for SO2 is -2.154 eV, the interface charge transfer amount is -0.49 e, and the Al-O interaction distance is 1.737 Å. The adsorption structure can be used for irreversible capture, enrichment and immobilized adsorption of SO2, and industrial waste gas desulfurization and capture of toxic gas containing sulfur.

Sorbent for lithium extraction from brines
Disclosed herein are compositions for extracting lithium from a brine, methods for utilizing compositions for extracting lithium from a brine, and / or methods for preparing a composition for extracting lithium from a brine. For example, a composition may include lithium aluminum hydroxide crystals having a crystal structure of a plurality of hexagonal sheets. In some instances, each of the plurality of hexagonal sheets includes one or more vacant sites. Moreover, the composition may include a plurality of reinforcing ions bonded to an outside edge of one or more of the plurality of hexagonal sheets. In some instances, the plurality of reinforcing ions supports the crystal structure of the plurality of hexagonal sheets when the composition is washed with a stripping fluid and maintains a separation distance between one or more of the plurality of hexagonal sheets.

Flexible high strength insulation cable material, method of manufacture and power cable
The application relates to the technical field of cables, and discloses a flexible high-strength insulated cable material, a preparation method and a power cable. The material formula comprises ethylene-propylene rubber, ethylene-octene copolymer, magnesium hydroxide, solid maleic anhydride, zinc methacrylate, alpha-methyl styrene dimer, dicumyl peroxide and compound antioxidants. During the processing, maleic anhydride is heated to open a ring and in-situ consumes free water on the surface of magnesium hydroxide, thereby improving powder dispersion; the alpha-methyl styrene dimer acts as a chain transfer agent to inhibit long-chain homopolymerization of zinc methacrylate and avoid the formation of hard and brittle crosslinking points in the matrix; and the polar grafting end and the hydroxyl group on the surface of magnesium hydroxide construct a reversible coordination network containing metal ion bonds. The application solves the problems of dehydration difficulty and crosslinking brittleness of high-filled flame-retardant materials, so that the material can dissipate strain energy through ion node slipping when being stretched or bent, and has high flame retardancy, high tensile strength and excellent flexibility.

ActiveCN121812710BPositive electrodesSecondary cells servicing/maintenanceChemical physicsElectrical battery
The application provides a halide electrolyte, a positive electrode sheet and a solid-state battery. The halide electrolyte comprises a core LiNbOX4 and a modified layer Li y+2w‑3x A x M w X y ; X is one or more of fluorine, chlorine, bromine and iodine, A is at least one of Al and Ga, M is at least one of O and S, 0.5<=x<=3, 0.5<=w<=2, and y>=1. The modified layer material has an A-X ionic bond which is easily polarized. Under stress, plastic deformation is more likely to occur through the slippage and recombination of the ionic bond, the solid-solid interface contact impedance is reduced, and the rate performance is improved. The modified layer with a low reduction potential forms a potential barrier on the surface of the core, isolates the electron transmission path between the LiNbOX4 electrolyte and the electrode, avoids the reduction reaction of Nb 5+ , reduces the reduction potential of the halide electrolyte, widens the electrochemical window, and improves the cycle performance of the battery.
