Abstract: A fire suppression composition and method of encapsulation, thermal runaway prevention is provided. The fire suppression composition includes exfoliated vermiculite mixed with a liquid propellant, wherein the composition is chemical free, non-toxic, and biodegradable. Performance additives may be optionally added to improve the performance of the fire suppression composition. The fire suppression composition is intended for a variety of uses, and fire fighting systems. Although it may be used to fight a variety of fires, it is particularly useful for lithium ion battery fires. The exfoliated vermiculite is configured to encapsulate the object or substrate on fire, preventing thermal runaway and escalating fire situations.
