Structures of Solids

17.6K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Balancing Redox Equations

61.7K
Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

Standard Electrode Potentials

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Recrystallization: Solid–Solution Equilibria

2.8K
Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

Redox Reactions

58.5K
Oxidation-reduction or redox reactions involve the transfer of electrons from one molecule or atom to another. When an atom gains an electron, another atom must lose an electron, meaning oxidation and reduction must occur together. Since the redox occurs in pairs, the atom that gets oxidized is also called the reducing agent or reductant, and the atom that is reduced is also called the oxidizing agent or oxidant. A straightforward way to remember the definitions of oxidation and reduction is...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Solid-state Chemistry

Background:

  • Solid-solution cathode materials offer improved structural stability and cyclability in lithium-ion batteries due to single-phase reaction mechanisms.
  • Understanding the transition between two-phase and single-phase reactions is crucial for optimizing cathode performance.

Purpose of the Study:

  • To investigate the Li+-extraction/insertion mechanism in LiFe1-xVxPO4F solid-solution cathodes by tuning the Fe/V stoichiometry.
  • To determine how altering cation composition influences the chemical reactivity and phase behavior.

Main Methods:

  • Synthesis of LiFe1-xVxPO4F solid-solution powders (x = 0–1) using a one-step solid-state method.
  • Characterization of electrochemical behavior using cyclic voltammetry (CV), charge/discharge profiles, and open-circuit voltage (OCV) measurements.

Main Results:

  • Observed single-phase behavior (broad CV peaks, sloping profiles) for LiFe1-xVxPO4F cathodes when 0 < x < 1, contrasting with the two-phase behavior of end-members.
  • Identified that cation electronegativity (for Fe2+/3+) and M-O4F2 bond length (for V3+/4+) are dominant factors in redox potential and V couple behavior, respectively.

Conclusions:

  • The stoichiometry of Fe/V cations in LiFe1-xVxPO4F effectively controls the transition from two-phase to single-phase reaction mechanisms.
  • This control over reaction pathways leads to enhanced structural stability and cyclability, crucial for advanced lithium-ion battery applications.
