Abstract

A lithium-ion battery module includes a housing having a plurality of partitions configured to define a plurality of compartments within the housing. The battery module also includes a lithium-ion cell element provided in each of the compartments of the housing. The battery module further includes a cover coupled to the housing and configured to route electrolyte into each of the compartments. The cover is also configured to seal the compartments of the housing.

Claims

1. A lithium-ion battery module comprising:

a plastic housing having a plurality of compartments within the housing;

a plurality of lithium-ion cell elements, one of the lithium-ion cell elements being provided in each of the compartments of the housing; and

a cover coupled to the housing, wherein the cover is configured to seal each of the compartments of the housing; and

a permeability barrier configured to block water from reaching the plurality of lithium-ion cell elements, wherein the permeability barrier comprises a plurality of metal foil pouches, wherein each metal foil pouch is disposed about a respective lithium-ion cell element, and wherein each metal foil pouch comprises an open end.

2. The battery module of claim 1, wherein the cover is configured to route electrolyte into each of the compartments, and the open end of each metal foil pouch is configured to receive the electrolyte routed into the corresponding compartment.

3. The battery module of claim 2, wherein the cover comprises a channel having a plurality of apertures in fluid communication with each of the compartments to facilitate routing of the electrolyte into each of the compartments through the plurality of apertures.

4. The battery module of claim 1, wherein the housing further comprises solid tubes disposed along a perimeter of the housing and configured for thermal management of one or more of the cell elements, and the battery module further comprises a thermal conduction plate conductively coupled to the solid tubes.

5. The battery module of claim 3, wherein the channel is defined by an upper surface of the cover.

6. The battery module of claim 1, wherein each metal foil pouch comprises:

a top side proximate to one or more terminals of the corresponding lithium-ion cell element; and

a bottom side disposed opposite to the top side, wherein the bottom side is closed.

7. The battery module of claim 6, wherein the top side of each metal foil pouch comprises the corresponding open end.

8. The battery module of claim 1, wherein each metal foil pouch is flexible and electrolyte is disposed inside each metal foil pouch.

9. The battery module of claim 1, wherein the housing does not comprise a metal permeability barrier.

10. The battery module of claim 1, wherein each lithium-ion cell element comprises a first electrode and a second electrode, and each lithium-ion cell element does not comprise a housing separate from the corresponding metal foil pouch.

11. A lithium-ion battery module comprising:

a plastic housing having a plurality of lithium-ion cell compartments within the housing;

a plurality of lithium-ion cell elements, one of the lithium-ion cell elements of the plurality of lithium-ion cell elements being provided in each of the lithium-ion cell compartments of the housing;

a cover coupled to the housing, wherein the cover is configured to seal each of the plurality of lithium-ion cell compartments of the housing; and

a permeability barrier configured to block water from reaching the plurality of lithium-ion cell elements, wherein the permeability barrier comprises a plurality of metal foil pouches and each metal foil pouch is disposed about a respective lithium-ion cell element, and wherein each metal foil pouch acts as a terminal of the respective lithium-ion cell element.

12. The battery module of claim 11, wherein a top side of each metal foil pouch is closed, and wherein the top side acts as the terminal of the respective lithium-ion cell element.

13. The battery module of claim 11, wherein each metal foil pouch is in electrical contact with at least one electrode of the respective lithium-ion cell element.
