Formation of Complex Ions03:45

Formation of Complex Ions

24.8K
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...

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...

Electrodeposition

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.

Ionic Crystal Structures02:42

Ionic Crystal Structures

16.1K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Electrolysis

28.8K
In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...

Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

46.6K
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
  • Energy Storage

Background:

  • Aqueous zinc batteries face challenges from water decomposition and dendrite growth.
  • A dense, ion-conductive solid electrolyte interphase (SEI) is crucial for inhibiting the hydrogen evolution reaction (HER).

Purpose of the Study:

  • To design a low-concentration electrolyte for in situ formation of a robust bilayer SEI.
  • To enhance Zn-ion diffusion and suppress water penetration in aqueous zinc batteries.

Main Methods:

  • Utilized a mixed aqueous electrolyte of Zn(OTF)2 and Zn(NO3)2.
  • Investigated the in situ formation mechanism of the inorganic-organic bilayer SEI on the Zn anode.
  • Evaluated battery performance using Ti∥Zn and Zn∥MnO2 cells.

Main Results:

  • Successfully formed a bilayer SEI composed of ZnF2-Zn5(CO3)2(OH)6 (inorganic inner layer) and an organic outer layer.
  • Achieved a high Coulombic efficiency of 99.8% for 200 hours in Ti∥Zn cells.
  • Demonstrated high energy density (168 Wh/kg) with 96.5% retention over 700 cycles in Zn∥MnO2 cells.

Conclusions:

  • The in situ formed bilayer SEI effectively promotes Zn-ion diffusion and suppresses water decomposition.
  • The developed electrolyte system significantly improves the stability and performance of aqueous zinc batteries.
