Abstract

Coating a battery cell, or at least one battery cell in an assembly of battery cells or in a battery, or coating an assembly of battery cells or a battery which contains a battery cell or such an assembly with a fire-resistant coating is effective for protecting the cell, assembly, and battery and for retarding fire propagation.

Claims (28)

1 . A battery cell, in which at least a portion of the exterior of said battery cell is coated with a fire-resistant coating.

2 . A battery cell according to claim 1 , wherein said fire-resistant coating is an ablative coating.

3 . A battery cell according to claim 1 , wherein said fire-resistant coating is an intumescent coating.

4 . A battery cell according to claim 1 , wherein said fire-resistant coating is an endothermic coating.

5 . An assembly of battery cells, which comprises at least one battery cell according to claim 1 .

6 . A battery, which comprises at least one battery cell according to claim 1 .

7 . A battery, which comprises at least one assembly of battery cells according to claim 5 .

8 . A method of preparing a battery cell, said method comprising:

coating at least a portion of the exterior of said battery cell with a fire-resistant coating.

9 . A method according to claim 8 , wherein said fire-resistant coating is an ablative coating.

10 . A method according to claim 8 , wherein said fire-resistant coating is an intumescent coating.

11 . A method according to claim 8 , wherein said fire-resistant coating is an endothermic coating.

12 . A method of preparing an assembly of battery cells, said method comprising:

coating at least a portion of the exterior of said assembly with a fire-resistant coating.

13 . A method according to claim 12 , wherein said fire-resistant coating is an ablative coating.

14 . A method according to claim 12 , wherein said fire-resistant coating is an intumescent coating.

15 . A method according to claim 12 , wherein said fire-resistant coating is an endothermic coating.

16 . A method of preparing a battery which contains at least one battery cell or at least one assembly of battery cells, said method comprising:

coating at least a portion of the exterior of said battery with a fire-resistant coating.

17 . A method according to claim 16 , wherein said fire-resistant coating is an ablative coating.

18 . A method according to claim 16 , wherein said fire-resistant coating is an intumescent coating.

19 . A method according to claim 16 , wherein said fire-resistant coating is an endothermic coating.

20 . A method according to claim 8 , wherein said battery cell is a secondary, rechargeable battery cell.

21 . A method according to claim 8 , wherein said battery cell is a primary, single use battery cell.

22 . A method according to claim 8 , wherein said coating serves to retard fire propagation.

23 . A method according to claim 8 , wherein said coating serves to direct an incendiary event.

24 . A battery cell according to claim 1 , which is a lithium-based battery cell.

25 . A method according to claim 8 , wherein said battery cell is a lithium-based battery cell.
