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
exact text as granted — not AI-modified1 . 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.Cited by (0)
