Abstract
Disclosed herein are a lithium ion battery fire suppressant capable of effectively suppressing a fire of a lithium ion battery and a lithium ion battery fire suppression sheet including the same. The lithium ion battery fire suppressant includes an extinguishing powder and an organic binder mixed with the extinguishing powder.
Claims5
A lithium ion battery fire suppressant for suppressing a fire of a lithium-ion battery, comprising:
- a fire-extinguishing powder;
- and
- an organic binder mixed with the fire-extinguishing powder,
- wherein the fire-extinguishing powder comprises a mixture of an alkali metal inorganic carbonate powder, an alkaline earth metal inorganic carbonate powder, and an ammonium-based inorganic carbonate powder;
- wherein the organic binder comprises at least one of an organic adhesive and an elastomer, and the alkali metal inorganic carbonate powder comprises at least one selected from the group consisting of sodium carbonate (Na2CO3), sodium bicarbonate (NaHCO3), and potassium bicarbonate (KHCO3);
- wherein the alkaline earth metal inorganic carbonate powder comprises at least one selected from the group consisting of magnesium carbonate (MgCO3), calcium carbonate (CaCO3), and calcium bicarbonate (Ca(HCO3)2);
- wherein the ammonium-based inorganic carbonate powder comprises at least one selected from the group consisting of ammonium carbonate ((NH4)2CO3) and ammonium bicarbonate (NH4HCO3);
- wherein a first fire suppression process occurs at a first temperature due to the ammonium-based inorganic carbonate powder, a second fire suppression process occurs at a second temperature higher than the first temperature due to the alkali metal inorganic carbonate powder, and a third fire suppression process occurs at a third temperature higher than the second temperature due to the alkaline earth metal inorganic carbonate powder, thereby delaying fire spread in conjunction with the fire suppression processes.
5 more elements
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:
- a fire-extinguishing powder;
- and
- an organic binder mixed with the fire-extinguishing powder,
- wherein the fire-extinguishing powder comprises a mixture of an alkali metal inorganic carbonate powder, an alkaline earth metal inorganic carbonate powder, and an ammonium-based inorganic carbonate powder;
- wherein the organic binder comprises at least one of an organic adhesive and an elastomer, and the alkali metal inorganic carbonate powder comprises at least one selected from the group consisting of sodium carbonate (Na2CO3), sodium bicarbonate (NaHCO3), and potassium bicarbonate (KHCO3);
- wherein the alkaline earth metal inorganic carbonate powder comprises at least one selected from the group consisting of magnesium carbonate (MgCO3), calcium carbonate (CaCO3), and calcium bicarbonate (Ca(HCO3)2);
- wherein the ammonium-based inorganic carbonate powder comprises at least one selected from the group consisting of ammonium carbonate ((NH4)2CO3) and ammonium bicarbonate (NH4HCO3);
- wherein a first fire suppression process occurs at a first temperature due to the ammonium-based inorganic carbonate powder, a second fire suppression process occurs at a second temperature higher than the first temperature due to the alkali metal inorganic carbonate powder, and a third fire suppression process occurs at a third temperature higher than the second temperature due to the alkaline earth metal inorganic carbonate powder, thereby delaying fire spread in conjunction with the fire suppression processes.
