Controlled-Potential Coulometry: Electrolytic Methods

663
Controlled-potential coulometry, also known as potentiostatic coulometry, employs a three-electrode system in which the working electrode's potential is precisely regulated using a potentiostat. Platinum working electrodes are utilized for positive potentials, while mercury pool electrodes are favored for extremely negative potentials. The platinum counter electrode is separated from the analyte using a membrane or salt bridge to avoid interference in the analysis.
The chosen potential...

Potentiometry: Membrane Electrodes

1.6K
Membrane electrodes, also known as p-ion electrodes, use membranes that selectively interact with free analyte ions, generating a potential difference across the membrane. The resulting membrane potential, known as the asymmetry potential, is not zero even when analyte concentrations on both sides of the membrane are equal. The membrane's response is typically not selective to a single analyte but proportional to the concentration of all ions in the sample solution capable of interacting at...

Potentiometry: Overview

Potentiometry is an analytical technique that measures the potential difference between two electrodes in an electrochemical cell without drawing any significant current that could alter the solution's composition. This method employs an indicator electrode, which exchanges electrons with the analyte solution, and a reference electrode with a constant potential. Each electrode is immersed in a solution comprised of two half-cells. In a conventional setup, the reference electrode serves as...

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...

Reference electrodes serve as a stable reference point for potentiometric measurements, while indicator and working electrodes react to variations in the composition of a solution.
The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Polymer Science

Background:

  • Solid-state polymer electrolytes (SPEs) improve lithium-metal battery safety but struggle with dendrite formation due to anode volume changes.
  • Lithium dendrites are a major safety and performance concern in next-generation batteries.

Purpose of the Study:

  • To develop a novel strategy for inhibiting lithium dendrite growth in solid-state batteries.
  • To investigate the role of directional electric fields generated by piezoelectric polymers in controlling lithium deposition.

Main Methods:

  • Fabrication of piezoelectric poly(vinylidene-co-trifluoroethylene) [P(VDF-TrFE)] nanofiber interphases with aligned dipoles.
  • Characterization of the generated electric fields and their effect on Li+ migration and deposition.
  • Testing of symmetric Li cells and LiNi0.8Co0.1Mn0.1O2 (NCM811)//Li full cells for stability and cycling performance.

Main Results:

  • The piezoelectric P(VDF-TrFE) interphase generated a directional electric field that steered Li+ deposition from dendrite tips to planar regions.
  • Achieved high ionic conductivity (5.0 × 10-4 S cm-1) and Li+ transference number (0.40).
  • Symmetric Li cells demonstrated 3000 h stability, and full cells retained 96% capacity after 400 cycles. Reversing the field direction negated these improvements.

Conclusions:

  • Directionally engineered piezoelectric fields in polymer interphases are crucial for effective dendrite inhibition.
  • This approach offers a new pathway for enhancing the safety and performance of lithium-metal solid-state batteries.
  • The study highlights the importance of controlling the orientation of piezoelectric fields for battery applications.
