Summary
This study introduces a novel ceramifiable silicone foam composite to prevent thermal runaway propagation in energy storage systems. The material forms a ceramic barrier, enhancing safety and durability.
Area of Science:
- Materials Science
- Chemical Engineering
- Energy Storage
Background:
- Thermal runaway propagation (TRP) poses significant safety risks in energy storage systems.
- Existing materials struggle to balance thermal insulation with impact toughness.
Purpose of the Study:
- To develop a gradient-laminated ceramifiable silicone foam composite.
- To address the trade-off between thermal insulation and dynamic impact toughness.
- To enhance safety in energy storage systems.
Main Methods:
- Integrating a polydimethylsiloxane foam matrix with a glass fiber fabric skeleton.
- Utilizing silane coupling agents for interfacial adhesion.
- Incorporating multiscale fillers for synergistic ceramicization.
Main Results:
- The composite exhibits robust mechanical durability and elasticity from -40 to 300 °C.
- It retains 93% residual stress after 1,000 compression cycles.
- The material transforms into a ceramic barrier, reducing heat release by 54.4% and providing 30+ min of thermal protection.
- Successfully confined thermal runaway to a single cell in battery module tests.
Conclusions:
- The developed composite effectively prevents thermal runaway propagation.
- It offers a scalable solution for intrinsically safe energy storage systems.
- The material demonstrates superior thermal insulation and impact resistance.
