The lithium ion battery fire suppressant includes an extinguishing powder and an organic binder mixed with the extinguishing powder.
Claims6
A lithium ion battery fire suppressant for suppressing a fire of a lithium ion battery, comprising:
- an extinguishing powder for delaying fire propagation in association with fire extinguishing operations, the extinguishing powder comprising:
- an ammonium-based inorganic carbonate powder configured to perform a primary extinguishing operation at a first temperature and comprising one selected from ammonium carbonate ((NH4)2CO3) and ammonium bicarbonate (NH4HCO3),
- an alkali metal inorganic carbonate powder configured to perform a secondary extinguishing operation at a second temperature higher than the first temperature and comprising one selected from the group consisting of sodium carbonate (Na2CO3), sodium bicarbonate (NaHCO3), and potassium bicarbonate (KHCO3), and
- an alkaline earth metal inorganic carbonate powder configured to perform a tertiary extinguishing operation at a third temperature higher than the second temperature and comprising one selected from the group consisting of magnesium carbonate (MgCO3), calcium carbonate (CaCO3), and calcium bicarbonate (Ca(HCO3)2);
- and
- an organic binder mixed with the extinguishing powder, the organic binder includes one or more selected from organic adhesives and elastomers.

A lithium ion battery fire suppression sheet comprising:
- a pair of fiber sheets;
- and
- a lithium ion battery fire suppressant for suppressing a fire of a lithium ion battery, the lithium ion battery fire suppressant being disposed between the pair of fiber sheets and comprising:
- an extinguishing powder for delaying fire propagation in association with fire extinguishing operations, the extinguishing powder comprising:
- an ammonium-based inorganic carbonate powder configured to perform a primary extinguishing operation at a first temperature and comprising one selected from ammonium carbonate ((NH4)2CO3) and ammonium bicarbonate (NH4HCO3),
- an alkali metal inorganic carbonate powder configured to perform a secondary extinguishing operation at a second temperature higher than the first temperature and comprising one selected from the group consisting of sodium carbonate (Na2CO3), sodium bicarbonate (NaHCO3), and potassium bicarbonate (KHCO3), and
- an alkaline earth metal inorganic carbonate powder configured to perform a tertiary extinguishing operation at a third temperature higher than the second temperature and comprising one selected from the group consisting of magnesium carbonate (MgCO3), calcium carbonate (CaCO3), and calcium bicarbonate (Ca(HCO3)2), and
- an organic binder mixed with the extinguishing powder, the organic binder includes one or more selected from organic adhesives and elastomers.
