Ionic Bonds00:42

Ionic Bonds

118.0K
Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Electrolyte and Nonelectrolyte Solutions

62.3K
Substances that undergo either a physical or a chemical change in solution to yield ions that can conduct electricity are called electrolytes. If a substance yields ions in solution, that is, if the compound undergoes 100% dissociation, then the substance is a strong electrolyte. Complete dissociation is indicated by a single forward arrow. For example, water-soluble ionic compounds like sodium chloride dissociate into sodium cations and chloride anions in aqueous solution.

Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

41.2K
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.

Electrolysis

26.0K
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 Strength: Overview01:12

Ionic Strength: Overview

1.3K
The ionic strength of a solution is a quantitative way of expressing the total electrolyte concentration of a solution. This concept was first introduced in 1921 by two American physical chemists, Gilbert N. Lewis and Merle Randall, while describing the activity coefficient of strong electrolytes. During the calculation of ionic strength (I or μ), all the cations and anions are considered. However, the concentration (c) of an ion with a greater charge number (z) has a greater contribution...

Extraction: Advanced Methods

425
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Unstable interphases in lithium metal batteries (LMBs) limit the use of high-capacity nickel-rich layered oxides (NCM811) at varying temperatures.
  • Conventional carbonate electrolytes struggle to maintain interfacial stability and ion transport kinetics.

Purpose of the Study:

  • To develop a bifunctional electrolyte additive (EAFP) that enhances interfacial stability and ion transport in LMBs over a wide temperature range.
  • To create a stable electrode/electrolyte interphase for improved NCM811 cathode performance.

Main Methods:

  • Incorporation of 1,3-propanesultone as an additive to create a tailored bifunctional electrolyte (EAFP).
  • Characterization of the cathode-electrolyte interphase structure and properties.
  • Electrochemical testing of Li||Li, Li||NCM811, and graphite||NCM811 cells across a wide temperature spectrum (-40°C to 60°C).

Main Results:

  • The EAFP additive formed a robust cathode-electrolyte interphase with an inorganic inner layer and organic outer layer, enhancing mechanical stability and flexibility.
  • The optimized interphase facilitated fast Li+ transport and suppressed electrolyte side reactions, leading to low overpotentials and stable cycling.
  • Li||Li cells demonstrated a lifespan of 1000 hours at 30°C, and Li||NCM811 pouch cells operated stably from -40°C to 60°C.
  • EAFP showed compatibility with LiFePO4 and LiCO2 cathodes, maintaining 67% retention after 1000 cycles.

Conclusions:

  • The developed bifunctional electrolyte (EAFP) effectively regulates the electrode/electrolyte interphase, enabling stable and high-performance operation of lithium metal batteries under wide temperature conditions.
  • This approach provides a pathway for developing all-weather lithium metal batteries for diverse applications.
  • The electrolyte's broad compatibility with different cathode materials highlights its potential for next-generation energy storage solutions.
