Crystal Growth: Principles of Crystallization

4.6K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Area of Science:

  • Electrochemistry
  • Materials Science
  • Energy Storage

Background:

  • Aqueous zinc-ion batteries (AZIBs) face challenges due to uncontrolled zinc (Zn) dendrite growth during anode plating, impacting safety and lifespan.
  • Current Zn plating typically follows a 2D growth pattern along prismatic directions, leading to hexagonal platelets that facilitate dendrite formation.

Purpose of the Study:

  • To develop an electrolyte engineering strategy using rare-earth ions to regulate Zn plating and suppress dendrite growth in AZIBs.
  • To investigate the mechanism of Zn plating regulation by rare-earth ions and its effect on anode morphology and battery performance.

Main Methods:

  • Electrolyte engineering with rare-earth ions.
  • Multiscale experimental analyses (e.g., microscopy, spectroscopy).
  • Computational modeling (e.g., density functional theory).

Main Results:

  • Rare-earth ions preferentially adsorb onto prismatic {10-10} facets of Zn, suppressing lateral growth.
  • Zn plating is redirected towards screw dislocation-driven growth along the [0001] axis.
  • Dendrite-free, dense, and uniform Zn layers are achieved, improving cycling stability and depth-of-discharge.

Conclusions:

  • The study challenges the assumption that dendrite suppression requires (0002)-oriented growth.
  • A scalable strategy for stable, dendrite-free Zn anodes in AZIBs is established.
  • New mechanistic insights into Zn plating dynamics are provided.
