Ionic Crystal Structures

14.0K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

40.1K
Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Layered oxide cathodes offer cost-effective, high-capacity energy storage.
  • Challenges include capacity decay and slow kinetics due to phase transitions and ion diffusion barriers.

Purpose of the Study:

  • To enhance the electrochemical performance of layered oxide cathodes.
  • To investigate the effect of Al3+ substitution on crystal structure and Na+ diffusion.

Main Methods:

  • Crystal structure modulation via Fe3+ site replacement with Al3+ in layered oxide cathodes.
  • Electrochemical testing including high-rate cycling and capacity retention analysis.

Main Results:

  • Al3+ substitution strengthened transition metal layers and enlarged Na+ diffusion pathways.
  • Modified cathodes showed improved high-rate performance (111 mA h g-1 at 5.0C) and cycling stability (73.88% retention after 500 cycles).
  • Bare cathodes exhibited lower performance (97.3 mA h g-1 at 5.0C, 48.42% retention).

Conclusions:

  • Al3+ substitution effectively restrains detrimental phase transitions and improves electrochemical kinetics.
  • Tuning crystal structure via ion substitution is a viable strategy for designing stable and fast-charging O3-type cathodes.
