Abstract:
In this work, nanoflower-like Na0.5VOPO4·2H2O with a large interlayer distance of 6.5295 Å is synthesized via a simple chemical precipitation method at room temperature. It is the first time that the potential of the Na0.5VOPO4·2H2O electrode as a cathode material for SIBs has been investigated, and it exhibits a high specific capacity (127 mA h g-1 at 0.2C), outstanding long-term cycling stability and superior reaction kinetics.

Anionic Chain-Growth Polymerization: Overview
Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
Opposing Charges Hold Ions Together in Ionic Compounds
Ionic bonds are reversible electrostatic interactions between ions...
