Batteries and Fuel Cells

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...

Electrolyte and Nonelectrolyte Solutions

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.

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...

Electrolysis

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: Effects on Chemical Equilibria

The addition of an inert ionic compound increases the solubility of a sparingly soluble salt. For example, adding potassium nitrate to a saturated solution of calcium sulfate significantly enhances the solubility of calcium sulfate. Le Châtelier's principle cannot predict this shift in the equilibrium. Instead, this could be explained in terms of changes in the effective concentration of the ions in solution in the presence of added inert salt.
In this solution, the primary...

Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

41.6K
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:

  • Traditional lithium-ion batteries face limitations in energy density.
  • Lithium-sulfur batteries (LSBs) offer higher theoretical specific capacities but suffer from severe capacity decay, especially at high currents.
  • Improving the stability and cycle life of LSBs is crucial for their practical application.

Purpose of the Study:

  • To investigate the effect of an ionic liquid (IL) electrolyte additive, TDA+TFSI, on the performance of lithium-sulfur batteries.
  • To evaluate the cycling stability, capacity retention, and high-current performance of LSBs with and without the TDA+TFSI additive.
  • To understand the mechanism behind the performance improvement.

Main Methods:

  • Incorporation of 5% TDA+TFSI ionic liquid additive into a traditional ether-based organic electrolyte for LSBs.
  • Electrochemical testing of LSBs, including cycling performance at 0.5 C and 1.0 C rates.
  • Analysis of discharge specific capacity, residual capacity, capacity decay rate, and Coulombic efficiency.
  • Investigation of the solid electrolyte interface (SEI) film formation.

Main Results:

  • LSBs with 5% TDA+TFSI additive exhibited significantly improved cycling performance compared to pure electrolyte.
  • At 0.5 C, residual capacities after 100 and 300 cycles were 579 mAh g⁻¹ and 523 mAh g⁻¹, with an average decay rate of 0.18% per cycle.
  • At 1.0 C, LSBs with the additive showed 13% higher residual capacities after 100 and 250 cycles, along with more stable Coulombic efficiencies.
  • The TDA+TFSI additive promoted the formation of a denser and more uniform SEI film.

Conclusions:

  • The TDA+TFSI ionic liquid additive effectively enhances the cycling performance and stability of lithium-sulfur batteries.
  • The improved performance is attributed to the formation of a stable solid electrolyte interface (SEI) film.
  • TDA+TFSI is a promising additive for developing high-energy-density and long-lasting lithium-sulfur batteries.
