Trends in Lattice Energy: Ion Size and Charge

23.8K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

Ionic Bonding and Electron Transfer

41.3K
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
  • Solid-State Chemistry

Background:

  • Lithium iron phosphate (LiFePO4) is a widely commercialized cathode material for lithium-ion batteries.
  • Its rigid one-dimensional lithium-ion diffusion channels limit fast charge and discharge capabilities.
  • Improving ion mobility in LiFePO4 is crucial for high-power battery applications.

Purpose of the Study:

  • To enhance the rate performance and cycle stability of LiFePO4 cathodes.
  • To engineer lattice flexibility and broaden lithium-ion diffusion pathways.
  • To investigate the effect of borate substitution on LiFePO4 electrochemical properties.

Main Methods:

  • Lattice engineering via substitution of tetrahedral PO4(3-) with planar triangular BO3(3-) groups.
  • Synthesis and characterization of LiFe(PO4)(0.98)(BO3)(0.02) material.
  • Electrochemical testing, including high-rate capacity measurements and long-term cycle stability analysis at various temperatures.

Main Results:

  • The modified LiFe(PO4)(0.98)(BO3)(0.02) exhibited significantly improved Li-ion diffusion channels.
  • Achieved high-rate capacity of 66.8 mAh g(-1) at 50 C and ultra-low capacity loss (0.003% per cycle) at 10 C at 25 °C.
  • Demonstrated excellent performance at -20 °C, with 34.0 mAh g(-1) at 40 C and no capacity loss after 2500 cycles at 10 C.

Conclusions:

  • Planar borate substitution effectively enhances LiFePO4 cathode performance by increasing channel flexibility and introducing additional diffusion paths.
  • The modified material shows superior high-rate capability and long-term cycling stability, even at sub-zero temperatures.
  • This approach offers a promising strategy for developing advanced lithium-ion batteries with improved power density and durability.
