Abstract

The disclosure provides a battery cell casing for holding a plurality of cell elements, each electrode structure in its own compartment. The disclosed casing eliminates the need for some individual cell walls and replaces them with shared wall partitions.

First claim

We claim:

1 . A multi-cell rechargeable battery, comprising:
a case containing one or more partitions dividing the interior of said case into a plurality of cell compartments; a rechargeable cell element disposed within each of the compartments of the case; and a plurality of electrical terminals.

2 . The multi-cell rechargeable battery of claim 1 , wherein the rechargeable cell element is selected from the group consisting of: a lithium-ion cell element, a nickel-cadmium cell element, and a nickel-metal hydride cell element.

3 . The multi-cell rechargeable battery of claim 2 , wherein the partitions are composed of a metallic material or a metalized material.

4 . The multi-cell rechargeable battery of claim 3 , wherein the metallic material or metalized material is selected from the group consisting of: aluminum, aluminum alloy, stainless steel, carbon steel, alloy steel, magnesium, magnesium alloy, titanium, titanium alloy, and metalized carbon-fiber.

5 . The multi-cell rechargeable battery of claim 3 , wherein the metallic material has a thermal conductivity of at least 10 W/(m K).

6 . The multi-cell rechargeable battery of claim 3 , wherein the metallic material is aluminum or aluminum alloy, and wherein each partition has a thickness of at least 0.53 mm, but not more than 0.75 mm.

7 . The multi-cell rechargeable battery of claim 3 , wherein the rechargeable cell element is a lithium-ion cell element.

8 . The multi-cell rechargeable battery of claim 2 , wherein the partitions are configured within the case to prevent transfer of an electrolyte between the compartments.

9 . The multi-cell rechargeable battery of claim 2 , wherein the case comprises an upper layer and a lower layer, and wherein the upper layer comprises at least two cell compartments and the lower layer comprises at least two cell compartments.

10 . An electric vehicle, the electric vehicle comprising the multi-cell rechargeable battery of claim 1 .

11 . A multi-cell rechargeable battery, comprising:
a case containing one or more partitions dividing the interior of said case into a plurality of cell compartments; a rechargeable cell element disposed within each of the compartments of the case; and a plurality of electrical terminals, wherein the case comprises an upper layer and a lower layer, and wherein the upper layer comprises at least two cell compartments and the lower layer comprises at least two cell compartments.

12 . The multi-cell rechargeable battery of claim 11 , wherein the rechargeable cell element is selected from the group consisting of: a lithium-ion cell element, a nickel-cadmium cell element, and a nickel-metal hydride cell element.

13 . The multi-cell rechargeable battery of claim 12 , wherein the upper layer comprises at least three cell compartments and the lower layer comprises at least three cell compartments.

14 . The multi-cell rechargeable battery of claim 12 , wherein the partitions are composed of a metallic material or a metalized material.

15 . The multi-cell rechargeable battery of claim 14 , wherein the metallic material or metalized material is selected from the group consisting of: aluminum, aluminum alloy, stainless steel, carbon steel, alloy steel, magnesium, magnesium alloy, titanium, titanium alloy, and metalized carbon-fiber.

16 . The multi-cell rechargeable battery of claim 14 , wherein the metallic material has a thermal conductivity of at least 10 W/(m K).

17 . The multi-cell rechargeable battery of claim 12 , wherein the rechargeable cell element is a lithium-ion cell element.

18 . A multi-cell lithium-ion battery, comprising:
a case containing one or more partitions dividing the interior of said case into a plurality of cell compartments; a lithium-ion cell element disposed within each of the compartments of the case; and a plurality of electrical terminals, wherein the partitions are composed of a metallic material or a metalized material.

19 . The multi-cell lithium-ion battery of claim 18 , wherein the metallic material or metalized material is selected from the group consisting of: aluminum, aluminum alloy, stainless steel, carbon steel, alloy steel, magnesium, magnesium alloy, titanium, titanium alloy, and metalized carbon-fiber.

20 . The multi-cell rechargeable battery of claim 18 , wherein the case comprises an upper layer and a lower layer, and wherein the upper layer comprises at least two cell compartments and the lower layer comprises at least two cell compartments.
