Area of Science:

  • Materials Science
  • Chemical Engineering
  • Fire Safety Engineering

Background:

  • Fire incidents in energy storage systems, particularly lithium-ion batteries, pose significant risks.
  • Current fire suppression methods using fluorine-based agents are limited by leakage from microcapsule shells, reducing effectiveness.
  • Degradation of microcapsule integrity compromises the stability and performance of fire suppressants.

Purpose of the Study:

  • To develop durable, stable microcapsules for enhanced fire suppression in energy storage systems.
  • To improve the containment of volatile, non-flammable agents within microcapsules.
  • To enhance the thermal stability and fire extinguishing performance of microencapsulated agents.

Main Methods:

  • Utilized complex coacervation for low-temperature microencapsulation.
  • Coated microcapsules with urea-formaldehyde (UF) resin to create a denser, more robust outer shell.
  • Investigated the structural integrity and performance of double-layered microcapsules compared to single-walled counterparts.

Main Results:

  • Developed double-layered microcapsules with an average diameter of 309 μm.
  • Achieved a stable outer shell with minimal mass loss (0.005%) over 100 days of storage.
  • Demonstrated significantly improved thermal stability, reduced core material loss, and enhanced fire suppression capabilities compared to single-walled microcapsules.

Conclusions:

  • The double-layered microcapsule structure effectively enhances durability and prevents core material leakage.
  • The urea-formaldehyde resin coating provides superior shell density and thermal stability.
  • These microcapsules are highly suitable for initial fire suppression in energy storage systems, especially with low-boiling-point agents.
