Molecular and Ionic Solids02:54

Molecular and Ionic Solids

17.4K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Colloidal precipitates01:09

Colloidal precipitates

708
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

Polymer Classification: Crystallinity

2.9K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Ion Exchange01:17

Ion Exchange

632
Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...

Cationic Chain-Growth Polymerization: Mechanism00:57

Cationic Chain-Growth Polymerization: Mechanism

2.4K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

Anionic Chain-Growth Polymerization: Overview01:20

Anionic Chain-Growth Polymerization: Overview

2.1K
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Polymer Science

Background:

  • Amorphous lithium aluminum titanium phosphate (LATP) nanoparticles are investigated for their potential in solid-state electrolytes.
  • Poly(ethylene oxide) (PEO) is a common polymer matrix for solid-state lithium-ion batteries.
  • Achieving uniform nanoparticle dispersion is crucial for maximizing interfacial benefits.

Purpose of the Study:

  • To investigate the development and impact of an interfacial region around LATP nanoparticles within a PEO matrix.
  • To optimize the dispersion of LATP nanoparticles in PEO for enhanced ionic conductivity.
  • To understand the mechanisms governing ion transport in the LATP-PEO composite.

Main Methods:

  • Water-based in situ precipitation method for nanoparticle synthesis and dispersion.
  • Controlled temperature scheduling during composite processing.
  • Ionic conductivity measurements at various temperatures and particle loadings.
  • Fourier-transform infrared spectroscopy (FTIR) to analyze polymer structure.
  • Transition state theory analysis of ionic conductivity temperature dependence.

Main Results:

  • An interfacial region with 30x higher Li+ mobility than the PEO matrix was observed around LATP nanoparticles.
  • A maximum conductivity of 3.80 × 10^-4 S cm^-1 at 20 °C was achieved at 25 wt% LATP loading.
  • FTIR analysis indicated increased polymer backbone disorder, facilitating cation migration.
  • Analysis revealed that activation entropy, rather than enthalpy, predominantly benefits thermally activated processes in the interphase.

Conclusions:

  • Uniform dispersion of LATP nanoparticles via in situ precipitation significantly enhances ionic conductivity in PEO-based solid electrolytes.
  • The enhanced conductivity is attributed to the formation of a highly conductive interfacial region around the nanoparticles.
  • The findings provide insights into designing high-performance solid-state electrolytes by controlling nanoparticle-polymer interfaces.
