Ionic Bonding and Electron Transfer

41.9K
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.

Interfacial Electrochemical Methods: Overview

323
Interfacial electrochemical methods focus on the phenomena occurring at the boundary between an electrode and a solution, as opposed to bulk methods that concentrate on the solution's overall properties. These interfacial methods are classified as either static or dynamic based on the presence of a nonzero current in the electrochemical cell and the consistency of analyte concentrations. Static methods, such as potentiometry, measure the cell's potential without any significant current...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Increasing the upper cut-off voltage of lithium cobalt oxide (LCO) is crucial for high-energy density lithium-ion batteries.
  • High-voltage operation exacerbates surface instability and safety concerns due to LCO's reactivity with electrolytes.

Purpose of the Study:

  • To construct a stable phosphate-rich cathode-electrolyte interface (CEI) on LCO particles.
  • To mitigate safety concerns and improve cycling stability in high-voltage LCO batteries.

Main Methods:

  • Electrochemical activation using fluoroethylene carbonate and 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether as solvents.
  • Formation of a phosphate-rich CEI layer on LCO particles.

Main Results:

  • The phosphate-rich CEI enhances physical and chemical stability.
  • The novel electrolyte solvents demonstrate high thermal stability, reducing flammability.
  • LCO cathodes achieved 76.1% capacity retention after 200 cycles at 4.6V.

Conclusions:

  • The developed CEI effectively blocks direct contact between LCO and electrolytes, improving surface structure and cycling stability.
  • The flame-retardant electrolyte contributes to safer high-voltage battery operation.
  • This study offers a new approach for designing high-voltage, safe battery systems.
