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...

Spontaneous Chemical Reactions
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Electrodeposition01:08

Electrodeposition

549
Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Zinc-ion hybrid supercapacitors (ZHSs) offer high energy and power density but suffer from unstable zinc anodes.
  • Poor electrochemical stability and slow kinetics of zinc anodes limit the practical application of ZHSs.

Purpose of the Study:

  • To develop a highly stable and fast-kinetics zinc anode interface for ZHSs.
  • To enhance the electrochemical performance and cycle life of ZHSs.

Main Methods:

  • Utilized sulfobutyl groups-grafted β-cyclodextrin (SC) supramolecules as a trace electrolyte additive.
  • Investigated the self-assembly of SC molecules on the zinc anode to form an interconnecting molecular interface.
  • Analyzed the interface's effect on Zn2+ transference, deposition kinetics, and parasitic reactions.

Main Results:

  • The SC-assembled interface improved Zn2+ transference number and homogenized deposition.
  • Achieved superior zinc anode reversibility with 99.7% Coulombic efficiency and a 30-fold increase in lifetime.
  • Developed ZHSs with a 20,000-cycle life and optimized rate capability.

Conclusions:

  • The electrolyte additive-assembled interface effectively stabilizes zinc anodes for ZHSs.
  • This strategy significantly enhances the electrochemical stability and kinetics of zinc anodes.
  • Provides a promising approach for advancing the development of high-performance ZHSs.
